Why is Tepid Water Important for Emergency Showers? 

Emergency showers, facewash stations, and eyewash stations are essential for prompt decontamination in workplaces prone to chemical spills or exposure to hazardous materials.

These stations, strategically located in areas like power plants, industrial facilities, and labs, allow individuals to rinse off harmful substances in case of emergencies.

The Importance of Tepid Water in Emergencies

The importance of tepid water -safety shower in use

Tepid showers are critical in protecting personnel and complying with regulatory requirements. If a person’s body and eyes are exposed to a corrosive and dangerous substance at work, they need instant access to a water supply to saturate their bodies and flush their eyes.

A consistent flow of tepid water from emergency showers and eyewash stations prevents thermal shock or burns and ensures effective flushing without discomfort.

Many facilities have emergency fixtures, including laboratories, chemical, petrochemical, pharmaceutical, manufacturing plants, agriculture and mining facilities, oil refineries, and educational facilities.

Let’s explore the importance of using tepid water in emergency showers and how it affects workplace safety.

What is Tepid Water?

Tepid degree water is defined as having a temperature between 60-100ºF (15.6-37.8ºC). This temperature range is considered suitable for providing comfort and preventing further injury when using an emergency shower, facewash, or eyewash station after bodily exposure to hazardous materials.

The ANSI Z358.1-2014 standard is a guideline for selecting, installing, operating, and maintaining safety showers, facewash stations, and eyewash stations.

The standard states where emergency fixtures need to be located, the required spray patterns, minimum flow rates, water temperature requirements, and the time the water needs to be supplied.

Why Do Emergency Showers Need Tepid Water? 

Having tepid water readily available from emergency showers is essential to operator safety. Temperatures too high could burn the employee or open their pores, allowing dangerous substances to sink into their skin. Too cold water can lead to hypothermia or shock. Here’s why tepid showers are crucial:

Effective Decontamination: Tepid water is optimal for flushing chemicals or contaminants from the eyes, face, and body in case of chemical spills, splashes, or exposure. It helps dilute and remove hazardous substances more effectively than water that is too hot or too cold, aiding in rapidly removing contaminants to minimize potential injuries.

Compliance with Regulations: Many safety regulations and standards, such as ANSI/ISEA Z358.1, require tepid water in emergency eyewash and safety shower systems. Compliance with these regulations ensures facilities provide appropriate emergency response measures to protect workers’ health and safety.

Extended Flushing Duration: Tepid water encourages longer flushing durations, as individuals are more likely to endure the discomfort of flushing contaminants from their eyes or skin with water that is neither too hot nor too cold. Longer flushing times enhance the effectiveness of decontamination and reduce the risk of injury. The tepid water temperature ensures the injured person can endure the recommended 15 minutes of continuous flushing.

Prevention of Further Injury: In cases of chemical exposure, using tepid water for decontamination helps to prevent thermal shock, which can exacerbate injuries and increase tissue damage. Tepid water promotes gentle yet thorough flushing to minimize the risk of further injury to affected individuals.

Types of Tepid Water Systems

Various tepid water systems for safety showers, facewash, and eyewash stations are available. These include mixing valves for hot and cold-water supply lines, turnkey systems with pre-packaged, self-contained heating and mixing valves, instantaneous electric heaters, and steam-fired heaters.

ThermOmegaTech’s Therm-O-Mix® steam-fired tepid water delivery system uses existing plant steam and water to supply face/eyewash stations and safety showers with tepid water.

The unit functions 100% mechanically, needing no external power source, making it ideal for explosive-proof environments. It’s self-purging, so no elaborate drainage or expensive recirculation systems are required.

If your facility does not have a steam supply, ThermOmegaTech also offers the heavy-duty ESS Emergency Safety Shower Water Heater, bundled with the Therm-O-Mix Station/Water-Water Mixing Valve (WWM).

What is a Mixing Valve?

A mixing valve is a mechanical device that controls fluid temperature, commonly water, lube oil, or hydraulic fluid, by blending hot and cold fluids to provide a consistent output temperature. They are crucial in various industrial, aerospace, and defense systems where precise fluid temperature control is necessary.

This article provides an overview of mixing valves: types of valves, how they work, and applications for use.

Types of Mixing Valves

Two primary categories are motorized and thermostatic mixing valves.

Motorized mixing valves, also known as motorized or electronically controlled valves, use an electric actuator or motor to adjust the position of the valve’s internal components. This motorized adjustment allows precise control over the hot and cold fluid ratio, which regulates the outlet temperature.

Motorized mixing valves are often controlled electronically through a dedicated controller and are commonly used in commercial and industrial settings where accuracy is paramount. They are frequently used in applications requiring integration with automation systems, such as large-scale HVAC (heating, ventilation, and air conditioning) systems.

Thermostatic mixing valves use a thermal element, such as a wax-based cartridge, to adjust the mixing valve automatically based on fluid temperature. The thermal element expands or contracts in response to temperature fluctuations, which regulates the flow to maintain a consistent output temperature.

Thermostatic mixing valves are self-actuating and do not require external power to operate. They are commonly used in engines, compressors, lubrication oil cooling systems, hydrostatic drive circuits, radiators, and hydraulic power units (HPUs).

The primary difference between these types of mixing valves is the control method. Motorized valves use electric actuators and electronic control systems, while thermostatic valves rely on self-operating thermal elements.

How Does a Mixing Valve Work?

A mixing valve usually has three inlet connections: one for hot flow, one for cold flow, and one for the mixed fluid outlet. The 3-way control valve modulates between the hot and cold inlet feeds (ports “B” and “C”) to mix your fluid to the desired specified temperature exiting the “A” port.

The mixing valve would ensure the fluid remains within the optimal temperature range, preventing overheating or excessive cooling. Such temperature extremes could result in system malfunctions or damage.

When temperatures surpass recommended limits, fluid viscosity decreases, leading to issues like poor lubrication, seal degradation due to thermal stress, and even occurrences of pump cavitation or failure, conversely, fluid viscosity increases when temperatures fall below the recommended range, causing undue stress on internal components due to insufficient lubrication.

Mixing hot and cold fluids in controlled proportions helps maintain consistent temperatures, ensuring efficient operation and longevity of components.

Do I Need a Mixing Valve?

Mixing valves ensure uniform temperatures, prevent overheating, and enhance process efficiency, making them indispensable components in various applications in manufacturing plants, chemical processing facilities, and other industrial facilities.

Without the intervention of mixing valves, fluctuations in temperature could lead to detrimental outcomes such as component degradation, equipment malfunction, and even safety hazards.

Diverting Valve vs. Mixing Valve: What is the Difference?

A Diverting Valve controls flow between multiple outlets or pathways and directs it to different system components.

A Mixing Valve controls fluid temperature by blending hot and cold fluids to achieve a consistent and safe output temperature.

Mixing valve

The primary distinction between mixing and diverting valves lies in their purpose: fluid temperature control vs. fluid routing. ThermOmegaTech offers a valve that can be used for mixing and diverting based on your application.

The flow direction of a port determines what makes it either a Mixing valve or a Diverting valve. For mixing applications, the valve will have two flow inlets and one outlet; in diverting applications, there is one inlet and two outlets.


In conclusion, mixing valves play a critical role in various industrial applications. They offer precise control over fluid temperatures and thereby enhance overall process efficiency.

Mixing valves’ versatility allows them to be applied in multiple settings, from large-scale industrial plants to smaller commercial systems. Whether regulating the temperature of water in a heating system, controlling the flow of coolant in an engine, or managing the temperature of hydraulic fluid in an HPU, mixing valves are essential in optimizing performance and ensuring reliability.

Freeze Protection Case Study: Bridge Over Frozen Waters

Ware Shoals, South Carolina, has been plagued in recent winters by expensive repairs caused by freezing pipes. One particular application, a two-inch line mounted on the Marion P. Carnell Bridge over the Saluta River, was especially troublesome. As a result, pipes were constantly being repaired, and water flow was interrupted to hydrants and a hydroelectric station.

The Opportunity

Eastern Industrial Supplies, Inc. had the solution. Jack Sullivan, Eastern’s senior product manager for steam products, recommended ThermOmegaTech freeze protection valves.

“Ware Shoals is my hometown,” said Mr. Sullivan. “Helping the city is much more than a business relationship. So, I was thrilled to introduce a technology to help them solve a problem. ThermOmegaTech freeze protection valves were the perfect answer to lower costs and improve city infrastructure operations.

The Installation of Freeze Protection Valves

freeze protection valve

Three HAT/FP valves were installed on the bridge to automate purging water from pipes before they could freeze.

The valves are set at 35°F to open reliably and without electricity or human interaction when water reaches a freezing point, which is critical to city operations and residents.

“We were very interested when Eastern Industrial Supplies suggested they have a solution, especially one made with stainless steel and didn’t require electricity or batteries,” said John Lake, owner of L&L Environmental, which manages maintenance operations for Ware Shoals.

“The water line on the Marion P. Carnell Bridge used to be compromised every time we had a cold snap,” said Jordan Gambrell, wastewater supervisor at L&L Environmental.

“The freeze protection valves held up, with no issues, the entire winter. When you are on call 365 days a year, it is reassuring to know I can sleep at night knowing those lines won’t blow when it gets cold,” he said.

The damage caused by freezing pipes isn’t just water under the bridge.

Eastern Industrial Supplies and L&L Environmental can use ThermOmegaTech freeze protection valves to ensure water reliably flows under a bridge to equipment critical to the city’s operations.

The Importance of Industrial Washdown Stations in Food Processing Facilities

Industrial washdown stations are often used in manufacturing, chemical or petrochemical, and food processing facilities as part of cleaning and sanitation procedures where maintaining hygiene is crucial. A bucket of water with a mop and a cleaning agent does not effectively sanitize a plant the way food processing cleaning equipment can.

Cleaning and Sanitation Procedures in the Food Industry

Food assembly workers on Plant Line

Using industrial washdown systems for food processing is important because they help to keep the facility clean and sanitary. They also help to prevent the spread of bacteria and viruses.

Authoritative agencies like the FDA have defined sanitation requirements that each facility must adhere to such as identifying hazards that could impact a production facility.

Food production and detergent residue, liquid, and airborne contamination, transient soil, and microorganisms often are present in food production facilities, which is why washdown stations are recommended in these corporations.

While the hazards present on a production line vary from facility to facility and depend primarily on the specific products produced, they all must be effectively and routinely removed to preserve sanitation and product quality.

Using food processing cleaning equipment can help to reduce costs, too. Regular maintenance and repair of equipment can help to reduce downtime, saving your facility time and money. Regular cleaning and disinfecting of surface areas can also help to reduce labor costs while following a daily process.

Food Processing Cleaning Equipment Limits Downtime

Industrial washdown stations can be used in both commercial and industrial production facilities and are described as stationary equipment that produces a high-pressure and high-temperature stream of water to remove debris while cleaning. However, when used in production facilities such as food processing for meat and dairy, this cleaning equipment offers a fast and efficient cleanup while maintaining sanitation standards.

Food processing cleaning equipment for food processing typically utilizes stations that produce water temperatures at 150°F (65.5°C) or above to quickly cleanse and sanitize surfaces like processing equipment, walls, floors, and other surfaces.

To properly follow cleaning and sanitation procedures for food processing, a washdown system frequently includes a mixing valve that combines hot and cold water along with an industrial-use cleaning agent, if needed.

Using Food Processing Cleaning Equipment Sanitize

Having efficient cleaning equipment in a food processing facility can provide several benefits. By keeping the facility clean, the risk of food contamination is minimized. Food allergies and foodborne illnesses caused by bacteria and viruses can be avoided.

ThermOmegaTech created several washdown systems that offer high-temperature sanitation and maintenance equipment necessary for industrial and food facilities, including steam and water washdown stations with hot water mixing unit hose stations.

To be even more effective, ThermOmegaTech created a specific mixing valve that combines steam and cold water to create a steam water mixing station that lowers the decibel sound in facilities while producing a flow of user-defined stream of water to efficiently sanitize, clean, and kill bacteria.

Choosing The Right Equipment for Food Plant Sanitation

Choosing the right washdown station for your facility can be a challenge. There are a few key factors that should be considered when choosing the equipment for food plant sanitation. Staff should receive proper training on the washdown station when using such as donning the correct clothing and protective gear as well as regularly inspecting and cleaning your equipment.

The ThermOmegaTech® STVM® Washdown Station is used in many processing facilities where a high-temperature washdown is required. The STVM® industrial washdown station combines steam and cold water at a user-set temperature using its proprietary mixing valve.

ThermOmegaTech Launches New Talking with TOTs Video Featuring STVM® Washdown Station

Video Focuses on High-Temperature Washdown Equipment For Industrial Sanitation

ThermOmegaTech is excited to introduce their newest Talking With TOTs video, featuring Senior Product Specialist Glenn Quinty on ThermOmegaTech’s STVM® Washdown Station.

“We know how critical it is to maintain a clean environment in food processing, dairy, beverage, chemical, petrochemical, and pharmaceutical facilities,” Quinty says. “High-temperature washdown equipment is used to quickly and efficiently clean and sanitize equipment in place to keep production running on time.”

Washdown stations are recommended in food production facilities where transient soil, food production residue, and microorganisms can be present. Not every facility encounters these hazards depending on the specific product it produces, but removing debris, cleaning, and sanitizing is essential to preserving sanitation and product quality.

Steam Water Mixing Valve for Sanitization

Simply put: sanitizing kills bacteria.

Industrial Sanitation comprises several sequences created to protect workers’ health and safety in industrial environments and designed to protect the environment from pollution and industrial waste.

With high temperature washdown equipment, industrial sanitation is achievable. In the Talking with TOTS video, Quinty takes viewers through the washdown process, demonstrating how ThermOmegaTech’s proprietary Silent Venturi Mixing Valve (STVM®) combines steam and water to a user-defined temperature.

STVM Steam and Water Washdown Station for Talking With TOTS for Industrial Sanitation

STVM® Steam & Water Washdown Station

“The steam and water mixing valve’s design is self-scouring, which prevents mineral buildup in tight spaces and reduces maintenance frequency. Maintaining competitor steam and water mixing stations can be time-consuming due to complex disassembly, special tooling requirements, and non-reusable components,” Quinty says.

The compact, reliable, and entirely mechanically operated STVM® Washdown Station is beneficial to any industrial processing plant’s sanitation procedures.

It is more durable and at least 8-15 decibels quieter when compared to competitor units, as found in recent testing.

How to Choose the Right High Temperature Washdown Equipment for Your Facility

Choosing the right washdown equipment can be a challenge, taking into account your facility’s needs and government regulations.

To minimize maintenance downtime and get production lines moving again, the STVM® station is in-line serviceable. The operator simply switches out the STVM® mixing valve cartridge with a spare using a standard wrench, and the unit is operational again in minutes. In contrast, competitor stations must be removed from the wall and completely disassembled to repair, which takes hours and results in more extended downtime.

Operator’s safety is another crucial element that positions the STVM® Station above the competition. Employees should wear the correct PPE (personal protective equipment — including gloves, masks, smocks, etc.) when operating any washdown equipment and have the proper training on the unit. In addition to these safety guidelines, our station has two safety features to help keep your employees safe.

“The mixing valve is designed to reduce flow if the output temperature exceeds the factory set-point and will completely stop flow 15°F above that,” Quinty notes in the video. “The station also has interlocking steam and water shut-off ball valves, so both inlets shut off at the same time to prevent accidental steam-only operation.”

Using food processing cleaning equipment can help to reduce costs, too. Regular maintenance and repair of equipment can help to minimize downtime, saving your facility time and money. Regular cleaning and disinfecting of surface areas can also help to reduce labor costs while following a daily process.

How an East Coast Rail Company Prevents Their Locomotives From Freezing

The GURU® Plug – The #1 Freeze Protection Valve

Freeze protection is essential for locomotives during winter months to prevent catastrophic damage to equipment. A diesel locomotive’s cooling system is at risk of freezing when the locomotive is turned off. If the cooling water freezes, it can cause the piping and tanks to crack, resulting in extensive damage, lengthy repairs, and interrupted schedules.

GURU PLUGOperators could keep their locomotives running at all hours to prevent a freeze-up, but that can contribute to air pollution and fuel waste. Another more cost-effective and efficient way is to install ThermOmegaTech’s GURU® Plug.

The Opportunity

The GURU® DL2.1  thermostatic drain valve is installed at the lowest point within the cooling system and automatically responds to engine coolant temperature.

The Plug will snap open and drain the system if the water temperature reaches the Plug’s set point, typically 35°F. This provides almost a full one-inch bore to rapidly drain a typical locomotive’s coolant system before freeze damage can occur. The Plug can be reset when the operator is ready to refill the locomotive and return it to service.

SMS Locomotive using GURU Plug

SMS Rail Lines, a one-stop provider of rail distribution services to businesses along the Washington, D.C. to Boston corridor, is based in Bridgeport, New Jersey, and has been using ThermOmegaTech’s GURU® Plugs for over a decade on their locomotive cooling systems and compressors.

SMS Rail Lines operates over 6 miles of track throughout Pureland Industrial Park in Bridgeport, New Jersey, providing service daily, including on-demand rail switching and daily interchange with Class I railways CSX Transportation and Norfolk Southern Corporation.

SMS Rail Lines also offers rail-to-truck and truck-to-rail transloading, warehousing, distribution services, and rail car storage at this location, with 12 locomotives in service at any given time. Additionally, the company restores, maintains, and operates historic Baldwin diesel locomotives.

Utilizing the GURU® Plug

“We normally have 12 to 14 locomotives in service at any given time,” General Manager Brian Murray explains. “Some of our locomotives have only a single GURU if they are plumbed in a way where everything can drain to a central location. We have a couple with a second GURU to handle additional low points in the cooling system. Our GE locomotives have 4 GURUs. They have 2 GURUs to handle low-point general draining and 2 on the low-pressure heads of the water-cooled air compressor.”

SMS operators have previously used other freeze protection devices on their locomotives. “We initially used ‘that other name brand.’ It would occasionally open while the engine was hot and running,” said GM Murray. Because of this, he looked for another solution and was introduced to ThermOmegaTech’s GURU® Plugs over ten years ago by then-product manager Dana Logue.

The GURU® Plug Rebuild Program

The GURU® Plug satisfied their needs and came with an additional perk – the GURU® Rebuild Program. ThermOmegaTech® offers a rebuild program for the self-actuating GURU® Plug, which protect thousands of locomotives from freeze damage annually. The program allows customers to return their old GURU® Plugs to be cleaned, refurbished, retested, and returned, so customers get back an almost brand new valve.

“We are very happy with ThermOmegaTech® and think the GURU® Plug is terrific. We have never had a GURU fail to open when necessary. As the end user, we should probably do a better job at keeping track of which GURU plug is in which locomotive and how old they are,” stated GM Murray.

Brian with Guru Plug

Luckily for SMS Rail Lines, there’s an easy way to track that!

Each GURU® Plug has a yearly-rotated color cap which is also laser marked with its month and year of manufacture. ThermOmegaTech® recommends changing the GURU® Plugs every 18-24 months, as the GURU® Plug’s actuator loses a small amount of stroke as it ages beyond one year. This stroke loss causes the release temperature and the manual reset temperature to creep upward. While this is a “safe” tendency for freeze protection, the upward creep can eventually cause nuisance dumping.

The colored caps rotate through 5 colors over 5 years and visually indicate the year it was built. Maintenance personnel can compare the cap’s color against our chart to determine when it needs to be sent back for rebuild. SMS has taken advantage of this perk and utilizes the rebuild program yearly.

“We send in about 4 or 5 valves per year for rebuilding to have them on hand. Our cost savings are significant as we have a lot of older GURUs around, so it makes sense to rebuild them,” says GM Murray.

And when they come back, rebuilt, and refurbished, GM Murray says they are good as new, and they’ve never had any issues.

The Result of the GURU® Plug

GURU Plug on locomotive

“In my experience, all the folks at ThermOmegaTech® are genuinely interested in providing to the railroad industry effective, reliable solutions. The staff is always accessible and willing to work cooperatively with the customer to examine the need and suggest the appropriate product,” says James Pfeiffer – Superintendent of Operating Practices.

“Customer feedback is welcomed, technical questions are quickly answered, and the engineering department is seemingly always working on something new and improved. And they do all this while maintaining first-class customer service.”

Full Steam Ahead: Sanitizing with Steam and Water Mixing Stations Whitepaper

Washdown stations ensure cleanliness in food processing, dairy, breweries, wineries, chemical, petrochemical, pharmaceutical, and other industrial facilities where a high-temperature washdown is required.

Traditional cleaning methods include soap, hot water, and sometimes chemical disinfectants. These procedures may require breaking down equipment to ensure all components are efficiently cleaned and sanitized. If chemicals are used to sanitize a processing plant, especially in food and beverage, labor costs, the possibility of safety hazards, and the overall sanitization time increase.

Utilizing a Steam and Water Mixing Valve to Sanitize Processing Plants

Sanitizing your facility or plant using a steam and water mixing valve is one of the most efficient ways. Using steam to heat the water is more beneficial than chemical cleansing because it avoids chemical agents and can reduce labor times and water consumption.

Steam and water mixing valve stations provide instantaneous high-temperature steam-heated water with pressure behind it, which can kill bacteria, sterilize, and break down greases and other residues in processing plants. The World Health Organization states that bacteria are rapidly killed at temperatures between 149°F and 185°F degrees.

There’s also less downtime for dismantling and reassembly when utilizing steam-heated water to sanitize manufacturing equipment. Steam is sterile as well as being an excellent carrier of heat. Harmful chemicals are also used less or not at all, allowing for more uptime and a safer environment for personnel; while they are doing their jobs.

Not just anyone can utilize high-temperature steam and water mixing washdown stations. Plant personnel must be trained on proper use to ensure safety because the goal is to sanitize, and the goal of the plant is safety.

STVM® Steam & Water Washdown Station

STVM Steam and Water Mixing Valve Washdown Station

ThermOmegaTech’s STVM® Steam & Water Washdown Station has been designed to put the safety of maintenance operators first. Every STVM® Washdown Station is built-to-last and has two built-in safety features – interlocking ball valves to prevent steam-only operation and an automatic shut-off when output is 15°F over the unit’s temperature set-point (either 150°F or 185°F) or when cold water flow is interrupted.

This Washdown Station also incorporates unique Venturi mixing technology to deliver water at the required temperature quickly, quietly, and on demand.

The ‘ST’ in STVM stands for ‘Silent Type,’ meaning it is quieter than other washdown mixing stations. The Venturi effect mixes water in smoother than other steam-to-water mixing stations on the market, which can cause cavitation downstream of the mixing valve.

The steam-supplied station is a self-contained mechanical control unit, so it doesn’t require external hookups for electrical, instrumentation controls, or compressed air.

Protect Your Employees From Freezing with Thermostatic Valves

Thermostatic Freeze Protection: Winter is the time to protect your pipes and personnel.

Water-bearing piping must be appropriately winterized to keep temperature-sensitive processes and equipment functioning optimally throughout the freeze season. When water lines to cooling and condensate systems, safety showers, and eyewash or facewash stations are left exposed to the elements, or their heat tracing fails, freezing temperatures can cause frozen or burst piping. This can lead to overheated equipment and severely dangerous working conditions for your employees, which can interrupt systems, burst piping, and cause lengthy and costly repairs.

If safety shower, eyewash, or facewash station water lines freeze, personnel could be at significant risk of being unable to cleanse after contamination exposure. Condensate drain lines are also in danger of freezing even if it is electrically heat traced and the tracing malfunctions or the facility loses power.

ThermOmegaTech’s self-actuating temperature control valves are the ideal water line freeze protection solution.

HAT/FP Freeze Protection Valve

The HAT/FP valve is designed to sense the water temperature in the pipe or ambient temperature, depending on installation. The valve will gradually open to bleed off the cold water when temperatures approach the valve’s set point, typically 35°F (1.6°C).

Once the flow is initiated, the valve will remain open until the discharge water temperature is 5 degrees above that, typically 40°F (4.4°C). Once the freeze danger passes, the valve will modulate closed again to conserve water and reduce wastewater disposal costs.

These 100% mechanical valves require no power source to operate, eliminating the human errors associated with manual valves. They can also save you thousands on your water or energy bills.

Result: Guaranteed freeze protection and water savings because of the reliable and automatic HAT/FP thermostatic valves.

Best Practices for Effective Safety Showers

Best Practices for Effective Safety ShowersRecently, an employee at a chemical plant was accidentally exposed to a caustic solution that the plant was processing. He ran to the nearest safety shower in order to rinse the caustic off. Unfortunately, the safety shower was malfunctioning.

Instead of tepid water in the 85°F (29° C) range, he was doused in water under 60° F (15.5° C). His initial reaction was to jump out, but his fellow employees held him under the cold water to rinse off the chemical. As a result, he ended up with hypothermia from the cold water.

In brief:

  • Federal regulations require you to flush supply lines to emergency showers and eyewash stations weekly.
  • The water passing through these devices must be at a temperature between 60°F and 100°F.
  • The showers/eyewashes must be placed strategically, depending on the plant’s physical layout.

Regulations and standards are intended to help keep employees and processes safe. Water temperature can mean the difference between whether an employee incurs permanent injury in an accident, whether outdoor processing facilities avoid expensive freeze damage, and whether a plant can keep operating without extensive maintenance. These matters are critical to operating a safe, compliant, and efficient plant. Continue reading

Winter is Coming – Use Freeze Protection Valves to Keep Lines Flowing

Winter is Coming - Use Freeze Protection Valves to Keep Lines Flowing - HAT/FP Freeze Protection ValveFreeze protection valves are effective in preventing freeze damage in process lines. Unlike steam or electric tracing, which require power and can cause water to overheat, freeze protection valves operate by simply draining or bleeding water as the temperature approaches freezing.

This prevents the formation of ice that can clog lines, shut off the flow, and cause pressure within the line to build, cracking pipes, valves, and fittings and damaging equipment. Damage due to ice formation can incur costs for replacement parts and labor and reduce productivity due to shutdowns.

Nonetheless, freeze protection valves do not necessarily completely prevent the formation of ice. In some cases, ice may still form as a layer on the inside of a pipe. This acts as a good insulator, reducing further heat loss to the cold outside air. Also, no damage will occur if the ice does not completely block the pipe or equipment flow area.

Damage due to freezing is caused when a pipe or flow passage in equipment is completely blocked. Then, as additional ice forms, the expansion associated with the ice formation compresses the water and causes a dramatic increase in the internal pressure in the line. When the pressure exceeds the pipe’s or housing’s strength, these will break.

Valves vs. Tracing

When to Use Tracing

Tracing is required when the temperature to be maintained is above the resupply water temperature; that is when additional heat input is required. Use tracing if the complexity of the equipment layout makes it difficult or impossible to bleed or drain the system properly. Also, tracing should be used if the discharge from bleeder or drain valves presents a handling problem. This may be the case in plant areas where all discharges must be controlled or reported or where discharge treatment problems and expenses outweigh the benefits of bleeder/drain valves.

When to Use Valves

Valves are generally more economical to install and operate than tracing. Use valves in remote plant areas where steam or electricity are not available and the cost to provide them is high. Also, use valves when potential overheating from tracing is a problem. In critical applications, where power failures will cut off electric or steam tracing, select self-operating valves as the primary or backup freeze protection system.

Circuit Solver Valve

Circuit Solver from ThermOmegaTech, Inc.

Circuit Solver is a self-actuating thermostatic recirculation valve which automatically and continuously maintains the end of each domestic hot water supply line at the specified water temperature. This simple inline valve completely eliminates the need for time consuming and expensive manual balancing procedures and equipment. By allowing only water that actually cools below the setpoint to flow to the return, the Circuit Solver also eliminates the need for oversized recirculation pumps which cause pipeline erosion and waste energy.

The Problem:
1. Water flows to the path of least resistance.
2. Many buildings require multiple branches off the hot water supply line.
3. Hot water use is hyper-dynamic, so the path of least resistance constantly changes.
4. Manual flow control valves cannot properly resolve these issues.

The Solution:
Install a Circuit Solver on each hot water supply branch line immediately downstream of the last run out to a hot tap.

Frost Valve for Solar Thermal

Frost Valve for Solar ThermalAustralia has the highest average amount of solar radiation of any continent, making it the perfect place for generating power or heating water with energy from the sun. Not surprisingly, the combination of generous rebates and sunny weather has given rise to solar thermal installations across the continent. Generally these installations are quite straightforward, but in the southern part of the continent, temperatures can drop below zero (Celsius), causing freezing problems for some thermal systems.
