Wisconsin Cheese Group Increased Uptime with STVM Washdown Stations

Wisconsin Cheese Group, LLC., is a manufacturer and distributor of Hispanic cheeses located in Monroe, Wisconsin. Operated by more than 30 employees, the facility identified a need for process sanitizing washdown stations.

For production facilities everywhere, time is money. Lines need to keep moving, batches completed, and deadlines met. The brief pause in the choreographed movements of people, parts, and products to sanitize equipment must be minimized to stay on track. Employees cannot be waiting around for water to warm up or for routine maintenance to be completed.

Wisconsin Cheese Group chose ThermOmegaTech’s STVM® Steam & Water Washdown StationWashdown Station to satisfy the plant’s need for consistent availability of high-temperature water. The STVM® Washdown Station delivers a high-temperature wash at a user-defined temperature using ThermOmegaTech’s proprietary mixing valve to combine steam and water. The mixing valve’s design is self-scouring, preventing mineral buildup in tight spaces and reducing maintenance frequency.

To minimize downtime during routine maintenance, the STVM® Washdown Station has a simple cartridge design and is in-line serviceable. The operator can simply switch out the cartridge with a spare, and the unit will be operating again in minutes.

The facility installed 12 STVM® Washdown Stations and has reported positive feedback. “We needed consistent hot water for sanitation, and we really liked the cartridge technology,” Dave Treuthardt of Wisconsin Cheese Group commented. “The washdown stations were easy to install and run effectively, leading to increased production time.”

Railroad Freeze Protection Winter Survival Guide

Here are a few freeze protection tips for surviving this winter with no frozen equipment, stranded cars, interrupted schedules, or schedule delays.

1. Monitor Weather Forecasts

According to a Railway Age article, the railroad industry suffers hundreds of millions of dollars in damages and lost profits every year due to weather-related incidents. Many of these occur from December through March due to winter storms bringing snow and ice that freeze pipes and blanket rails.

Freeze Protection

Consider implementing an intelligent weather monitoring platform that provides updated weather data and insights across various locations so that you can be prepared for unexpected weather extremes, no matter where your locomotives and passenger cars are.

2. Be Prepared to Clear The Rails

Implementing a snow & ice removal system throughout the winter will ensure safe and on-time rail service.

Here are some of the basics for using a system:

  • Inspect your grounds early on – clean switches, derails, frogs, and flangeways
  • Clear switch handles of any debris or snow build-up
  • Clear blockages from drains and gutters
  • Ensure railroad ties are visible
  • Keep a minimum depth of 1.5-inch clearance under flangeways

There are several different methods for keeping your tracks clear, including switch heaters, hot air blowers, and glycerin-based anti-freeze. Talk to a professional to determine the right one for your specific needs.

3. Winterize Locomotives & Passenger Cars with Freeze Protection Valves

Railroad tracks aren’t the only thing that needs to be winterized. Locomotives & passenger trains are at high risk of freezing during the winter months if left unprotected.

ThermOmegaTech recommends preventing fleet freeze-ups with the GURU line of thermostatic drain valves for locomotives and passenger cars.

Winterize Your Fleet

4 Benefits of Thermostatic Control in Lube Oil Systems

Thermostatic Control

Lubrication oil systems are designed to reduce wear, improve performance, and extend component and overall system life in many industrial applications. However, these systems can become compromised without a proper thermostatic control solution if temperatures are not adequately controlled.

Temperatures too hot = lower viscosity

  • Poor lubrication
  • Increased emissions
  • Higher internal leakage
  • Increased wear on bearings and seals
  • Thermal degradation of seals and other components

Temperatures too cold = higher viscosity

  • Poor lubrication
  • Increased wear
  • Pool fuel economy
  • High stress on pumps, valves, fittings, seals, etc

How to Maintain Optimal Temperature with TBV

ThermOmegaTech’s Thermal Bypass Valves (TBVs) use self-actuating thermostatic technology to constantly monitor inlet temperatures and automatically divert fluid to one of two outlet ports. The purpose is to ensure proper temperature control in lube oil systems by keeping the fluid temperature within a narrow and pre-defined range.

How TBV Thermostatic Control Valves Work

Cooler fluid will be directed through the bypass to the reservoir & recirculated through the system. Hotter fluid will be sent through the system cooler.

Thermostatic Control Valves

4 Benefits of Thermal Control

4 Ways Steam Water Mixing Valve Technology Reduces Downtime

The STVM® Steam and Water Mixing Valve Washdown Station is designed to provide a high-temperature washdown in food processing, dairy, breweries, wineries, chemical, petrochemical, and pharmaceutical facilities.

steam water mixing valve

Conventional washdown stations have multiple moving parts that generate loud and disruptive noise and have complicated maintenance procedures that slow down production.

ThermOmegaTech’s® STVM® Washdown Station remedies these pain points with 5 remarkable design features that reduce downtime, simplify maintenance, and keep operators safe.


1. Silent Type Venturi Steam Water Mixing Valve Technology (STVM®)

Incorporating our unique Venturi mixing technology, the STVM® Washdown Station delivers flow at a user-defined temperature quietly and on-demand.


    1. Cold water enters the mixing valve upper chamber
    2. Steam enters the lower mixing valve chamber
    3. The two vortices collide & mix through the Venturi diffuser
    4. Heated water is delivered with minimal noise and vibration

2. In-line Serviceable

To simplify maintenance and minimize downtime, the STVM® Washdown Station is in-line serviceable, with a cartridge design that is quick and easy to replace and doesn’t require any special tools.

Streamline Maintenance: Simply remove the STVM® cartridge with a wrench at the point of the installation and either replace it with a spare or clean the original using a descaling solution.

3. Interlocking Handles

To keep workers safe around steam, the STVM® Washdown Station features interlocking handles to decrease the likelihood of steam-only operation while still allowing for cold water only operation.

4. Automatic Over-Temp Shut-Off

To prevent over-temperature operation, the STVM® Washdown Station is designed to reduce the flow of steam should the output temperature exceed the unit’s factory set-point (150°F/185°F) and will completely shut off 15°F above that. The valve will restore steam flow once the temperature falls below the shut-off temperature.

The station will also stop flow should cold water supply be interrupted to prevent steam-only operation.

Alleviate Your Winter Worries With ThermOmegaTech’s Freeze Protection Valve

Freeze Protection Valve

We often talk about winter and the detrimental effects it can have on your locomotives and passenger cars if left unprotected against the season’s unrelenting wrath. ThermOmegaTech urges railroad operators to protect their rolling stock with the GURU freeze protection valve. However, there are many other freeze protection factors to consider during your winter prep.

Here are some pro tips on making it through winter while avoiding frozen equipment, malfunctioning cars, and interrupted schedules and delays.

1. Monitor Weather

Cold water can descend suddenly and unexpectedly, which is why it is often advantageous to include weather forecasting in your winter operations. According to a Railway Age article, the industry suffers from hundreds of millions of dollars due to weather-related damages each year, many of which occur throughout December – March due to snow and ice.


Railroad operators should consider implementing a weather intelligence platform that provides weather data and insights across various locations to be prepared for unexpected weather extremes.

2. Winterize Your Railroad Tracks

Just like frozen roads can be a hazard to cars, busses, and trucks, railroad tracks can have the same dangerous effect on rail cars. Implementing a snow and ice removal system is crucial for safe and on-time rail service throughout the winter season. Here are the basics for implementing a system:

  • Inspect your grounds early on – clean switches, derails, frogs, and flangeways
  • Clear switch handles of any debris or potential snow build-up
  • Clear drains and gutters from any blockage
  • Ensure railroad ties are visible
  • Keep a minimum depth of 1.5-inch clearance under flangeways


Many different methods can be implemented to keep your tracks winterized throughout the season, including switch heaters, hot air blowers, and glycerin-based anti-freeze. Keeping your tracks free of snow and ice will ensure timely switches and safe operation.

3. Implement Freeze Protection Valves on Your Locomotives and Passenger Trains

ThermOmegaTech recommends preventing fleet freeze-ups with the thermostatic GURU freeze protection valve.

Self-operating and compact, the GURU valve for locomotives and the GURU PC valve for passenger cars are designed to continuously monitor water or air temperatures to automatically drain cold water before it can freeze and cause damage.

100% mechanically operated, these valves require no source of electricity to operate and are trusted by all the Class 1’s in North American and other major railroad operators to protect their equipment each winter season.

Locomotive Freeze protection Valve

Implementing ThermOmegaTech’s reliable thermostatic freeze protection valve technology into your annual winter prep procedures will ensure your equipment is protected from freeze damage, lengthy repairs, and interrupted schedules all winter long.

4. Have a Plan: Act Fast 

Winter can be a challenging time for railroad operators; however, with a well-structured, comprehensive winterization plan, you can have a stress-free season knowing your equipment is protected from freezing.

Dana Logue, Rail Division Product Manager at ThermOmegaTech, suggests starting winter prep early before cold winds start blowing, as temperatures often dip sooner than people anticipate, leaving their equipment unprotected and open to freeze damage. Having a plan already in place while it’s still beach weather will mitigate the winter risks often seen in the railroad industry.

Heavy Duty Water Heater Guarantees On-Demand Tepid Water

Federal regulations require that any facility where workers may be exposed to hazardous or corrosive materials must have immediate access to a tepid water emergency drench or flushing system to protect the eyes and body in the event of accidental exposure.

As a guide, the ANSI Z358.1-2014 standard establishes a universal minimum performance and use requirements for all Eyewash and Drench Shower equipment.


ESS Tepid Water Delivery

ThermOmegaTech®’s Emergency Safety Shower (ESS) Water Heater is a factory-packaged tepid water delivery system specifically designed to comply with OSHA and ANSI standards.

This heavy-duty water heater is constructed of a carbon steel tank with an internal 1/2″ thick Hydrastone cement lining. It is fully insulated with 3″ thick polyurethane foam to minimize standby heat loss.


Factory-packaged with ThermOmegaTech’s Therm-O-Mix®/WWM mixing valve, the ESS combines cold and tank-heated hot water to deliver a constant 85°F tepid water outlet temperature at the point of use.

When an emergency safety shower/drench system is activated:

Tepid Water Delivery

Hot water from the water heater enters one port of the WWM mixing valve, as cold water from the facility supply enters the other. The water is mixed proportionately to achieve an OSHA-compliant 85°F supply to the station.

The ESS system will deliver tepid water for the recommended 15-20 minutes at 23 GPM for safety showers and 3 GPM for a face/eyewash station, even if the power goes out.

Designed to ensure employee safety, the unit incorporates a thermostatic over-temp shutoff that will prohibit overheated water from being released through the fixture and potentially scalding the user.

EcoFlow Double Mechanical Seal Support Valves Save Major U.S. Sugar Producer Money

The below case study features the EcoFlow thermostatic double mechanical seal support valve, a major U.S. sugar producer, and a substantial amount of savings.

Install Location Profile

A major U.S. sugar producer had several hundred pumps throughout their plant. Their pumps were either using packing, which required constant maintenance or using mechanical seals, which required a water supply to cool and flush it.

In the latter instance, the water is usually either returned to a seal water tank or dumped to drain. Any water that ends up on the floor or in a drain finds its way back to process and must be evaporated (large cost) or sent to wastewater (even larger cost). Both setups resulted in unnecessary costly water usage.

Prior to the adoption of ThermOmegaTech’s EcoFlow Mechanical Seal Support Valve, the plant faced several challenges:

  1. The plant could not use mechanical seals on their pumps due to the large water demand and up-front expense of a closed recirculation system.
  2. Packing was used in all pumps instead of double mechanical seals, which required leakage and constant maintenance.
  3. Expensive seals were damaged every year due to accidental dry running.

How The EcoFlow Helped

EcoFlow valves were placed on the seal water outlet of their pumps’ double mechanical seals to control the seal water temperature. The EcoFlow valve senses the seal water temperature and will modulate open to discharge the water if the temperature is too high, then modulate closed again once the flow cools to below the valves’ set-point.

EcoFlow Thermostatic Control Double Mechanical Seal Support Installation

More than 20 EcoFlow valves were initially installed at the plant. With great success and zero valve failures after two years, the plant is now planning to double its usage to a total of over 40 valves by the end of summer 2017.

Since installing EcoFlow thermostatic control valves, the plant has reduced dry running damages from four seals annually to zero. The implementation of EcoFlow valves has also reduced maintenance expenses, and provided an opportunity to use double mechanical seals in a situation which otherwise would not have been possible:

“EcoFlow allowed us to install double mechanical seals in places that we couldn’t have done so without an expensive closed loop seal water system. Now we run water to the seal and let the small amount of water the valve lets pass go to drain. We do not spec pumps with anything other than mechanical seal any longer. 100% of our replacements are now either a single or double seal, and each double gets the EcoFlow.”


By installing EcoFlow valves the plant was able to drastically decrease maintenance costs and reduce the amount of water that was sent to the drain.

“The seal manufacturer recommends 2.6 Gallons Per Minute to keep the seal below 180°F,  though the 135°F,  EcoFlow is putting out about 3 Gallons Per Hour.”

Assuming the seals operate 8 hours per day, 5 days per week, this equates to 2,080 hours of operation annually.

Seal Manufacturer Recommendation: 2,080 hours x 2.6GPM x 60 minutes
= 324,480 gallons per year


EcoFlow: 2,080 hours x 3.0GPH = 6,240 gallons per year


This equates to a savings of roughly 318,000 gallons of water annually for every seal equipped with EcoFlow.

EcoFlow Thermostatic Control Double Mechanical Seal Support Valves

The EcoFlow drastically decreases seal water consumption, only establishing flow when necessary to maintain consistent seal water temperature. This increases water treatment efficiency decreases operating costs and extends overall seal life by avoid dry running and maintain the optimum seal operating environment.

Get The Most Out Of Your GURU’s

Cold Water Refill Accessories

Over 95% of North American railroad operators rely on the GURU plug to protect their locomotives from freezing every winter. The tried-and-true GURU Plug monitors engine coolant water and will automatically drain the system should the water temperature  drop to 35°F or 40°F, depending on the valve’s set-point. This prevents the system from freezing and causing serious damage.

After the GURU Plug has “popped” and drained the system, the water storage tank must be refilled before the locomotive can be returned to service.  To shorten refill time and get your locomotives back up and running faster, ThermOmegaTech offers cold water refill accessories!

Cold Water Refill Tools

GURU Flag and Clip

Flag and Clip Cold Water Refill Tool for Locomotives

The clip at the end of the cable is inserted into the slot of the GURU plug’s resetting stem after warming the nose of the cartridge to keep the plug from “popping” as cold water is being added into the locomotive’s cooling system.

GURU Flag and Key

Flag and Key Cold Water Refill Tool for Locomotives

Used in conjunction with the anti-tamper domed cap, the key is inserted into the cartridge after warming its nose to keep it from “popping”. The plug’s resetting stem is not accessible, eliminating the ability to leave a penny or washer inserted.


The magnetic GURU flag with flashing light can be mounted to the side of the locomotive to serve as a visual reminder to remove the clip/key after refill.

By using one of these tools you prevent personnel from using a penny, washer or zip tie to keep the GURU Plug from “popping” and then forgetting to remove it before returning the locomotive to service thus rendering the valve ineffective in preventing freeze damage.

7 Reasons to Choose Thermostatic Control

7 Benefits of Thermostatic Control

When it comes to system performance in mission-critical aerospace and defense applications, thermal control is a leading factor in successful operation. Having an effective flow control device to balance temperature within the system ensures a more efficient and stress-reduced operation.

There are two commonly implemented types of flow control valves for A&D applications, solenoid valves and thermostatic valves.

Thermostatic Control

Thermostatic Vs. Solenoid

Solenoid valves require a complex set-up with multiple components external to the valve, as well as a source of DC power to operate which tends to increase installation expenses, space requirements, and the risk of operation failure in the case of a power outage or component failure.

ThermOmegaTech recommends thermostatic valves as the #1 thermally controlled flow solution for A&D applications. Precise, compact, and reliable, thermostatic valves are entirely self-powered and respond to narrow temperature variations to precisely control system flow, without the need for an external power source.

7 Benefits of Thermostatic Valves

Thermostatic control valves can be used for heating or cooling to effectively control temperature in various applications. Simplistically designed with paraffin wax actuator technology, these temperature control valves are versatile with a number of advantages that solenoid valves simply can not beat.

  1. Self-actuating
  2. Highly-repeatable
  3. Long service life
  4. Maintenance-free
  5. few moving parts
  6. Compact
  7. Unaffected by extremes – ideal for hazardous environments

Safety Shower & Eyewash Station Recommendations

Safety Shower & Eyewash Station ANSI Recommendations

Safety Shower in Use at Industrial Plant

Does your facility comply with industry standard safety recommendations for emergency safety shower and face/eyewash stations?

Any industrial facility that handles hazardous chemicals, debris, or other corrosive material must take the necessary precautions to ensure the safety of their employees. Installing a face/eyewash station that meets the appropriate flow requirements recommended by the ANSI is the first step to a safe working environment.

ANSI Z358.1-2014 Standard Flow & Temperature Recommendations:

  • Flow requirement for safety showers min. of 20 GPM at 30 PSI
  • Flow requirement for eyewash min. of 0.4 GPM at 30 PSI
  • Flow requirement for safety shower/eyewash station combination min. of 3.0 GPM at 30 PSI
  • Temperature requirement for all emergency station outputs uninterrupted tepid water (60-100°F [16-38°C]) flow for at least 15 minutes.

Failing to meet these flow and temperature recommendations can result in serious long-term damage to the users eyes, skin, limbs or other body parts due to scalding or insufficient removal of hazardous material.

To ensure an emergency fixture is able to meet the minimum-flow requirements as detailed by ANSI’s Z358.1-2014 standard, it’s important to consider plumbing line size, water quality and the tepid water delivery system being used. Click here to see what ANSI z358.1-2014 recommends.

Thermostatic Steam Valves Can Save You Thousands

Steam Valves: Improve Your Winterization Process & Your Savings

Steam tracing emptying your wallet each winter? It may be because you are using a manually controlled steam tracing system.

While manually controlled steam tracing is an effective method to eliminate the chance of freeze damage, these systems can have two common risks:

  1. Forgetting to turn the system on due to human error – resulting in freeze damage
  2. Not turning them off during non-freezing periods – wasting steam when unnecessary and ballooning costs

To significantly reduce steam costs over the freeze season, ThermOmegaTech recommends using a thermostatically controlled steam tracing solution. In these systems, steam is controlled by a thermostatic valve that continuously monitors temperatures, turning steam supply on only when the temperature falls towards freezing, and automatically turning it off to conserve supplies on warmer days.

Thermostatic steam valves eliminate the risks associated with human error, while ensuring the heating media is effectively used, resulting in a significant cost savings over a single freeze season.

Steam Valves - Save Thousands

What Your Facility Could Be Saving

A winterizing steam tracing system in a plant located in Philadelphia, PA consumes about 500 lbs. per hour of steam. This system was manually turned on in the beginning of the freeze season (mid-September) and was not turned off until the dangers of freezing temperatures passed (mid-April). Total operating hours are an estimated 5,088:

Cost of Manual Operation
When using a manually controlled system where steam is constantly on from September to April:

500 lbs. per hour x 5,088 hours x $8.00/thousand lbs. = $20,352.00 per winter season.

Cost of Thermostatic Operation
When using thermostatic control valves that turn off steam when temperature rises above 45°F:

500 lbs. per hour x 2,895 hours x $8.00/thousand lbs. = $11,580.00
per winter season.

*Based on U.S. Weather Bureau data for Philadelphia, steam will be on for only 2,895 hours each winter.

ESTIMATED SAVINGS = $8,772.00 per year

Save Money With The GURU Rebuild Program

Are You Due For a GURU Rebuild?

Cold weather is quickly approaching, and most locomotive operators have already begun their annual winter prep. In anticipation of freezing temperatures, we recommend evaluating your currently installed GURU Plugs and rebuilding those that have been in service for more than 18-24 months via the GURU Rebuild Program

Why Rebuild Your GURU Plugs?

As your GURU ages, there is an inherent tendency for its internal thermal actuator to lose a small amount of stroke. While this would never compromise your freeze protection, this tendency results in an upwards release temperature creed, which can cause nuisance dumping above the valve’s set-point.

To prevent this upward creep in nuisance dumping, ThermOmegaTech offers the GURU Rebuild Program, an easy and economical way to restore used GURU plugs to full functionality.

GURU Rebuild Program

How It Works

To participate in the Rebuild Program, used GURU Plugs must first be returned to our production facility with a purchase order. We then disassemble the valve, clean the cartridge body and hex nut, and replace its interior components. After reassembly, the refurbished GURU Plug is thoroughly tested to ensure full functionality before being returned to the field.

How To Know You Are Due For A Rebuild

Each GURU’s Plug has a yearly-rotated color cap which is also laser marked with its month and year of manufacture.

GURU Rebuild Color Chart

If it has been at least 18-24 months since a valve’s manufacture date, you should consider a rebuild.
