STVM® Steam & Water Washdown Station

Operation

ThermOmegaTech’s STVM® Steam & Water Washdown Station incorporates unique Venturi mixing technology to deliver water at the required temperature quickly, quietly, and on-demand. Cold water enters the upper chamber of the mixing valve, while incoming steam enters the lower chamber. Mixing occurs as the two vortices collide, thoroughly mixing and heating the water through a Venturi diffuser with minimal noise and vibration.

STVM® Steam & Water Washdown Station - Venturi Flow Animation

Conventional washdown stations, utilizing old spool and diaphragm technology that rely on multiple moving parts are prone to premature failure due to mineral deposits and scaling. The necessary regular maintenance of these units to keep them running safely is very time-consuming and costly. The rugged STVM® Washdown Station is unique in that it has only one moving part, a thermal actuator within the mixing valve cartridge.

The patented mixing design ensures long uninterrupted use even if there is high mineral content in the water. As the opposing vortices of steam and water enter the mixing valve, a scouring action occurs that minimizes the buildup of minerals and scale.

Venturi Mixing Diagram

 

An additional benefit of this design is what you don’t hear: the banging, popping, and crackling noises associated with cavitation that are prevalent in ordinary mixing stations. This smooth quiet operation increases safety and reduces stress on the operator.

Safety is our priority, so every STVM® Washdown Station 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.

STVM® Steam & Water Mixing Valve

Operation

During operation, cold water enters the mixing valve and moves from the inside out, while incoming steam moves from the outside in. Mixing occurs as the two flows collide, thoroughly mixing and heating the water to the desired temperature with minimal noise and vibration. Because of the unique mixing characteristics inside the STVM® valve, it is capable of mixing steam and water without the usual noise and vibration associated with other types of mixers, eliminating operator stress, and making it ideal for workplace environments.

The unique flow characteristics of the vortices inside the valve create a scouring action that minimizes the effects of mineral deposits on valve operation, assuring increased service life even under adverse conditions. As a safety feature, the thermal actuator in the valve outlet is designed to turn off the steam flow into the valve if the cold water flow into the valve is interrupted.

The entire internal operating mechanism (cartridge) of the STVM® valve can be quickly and easily removed as a single assembly by simply unscrewing the valve cap. This allows easy cleaning and service without removing the valve from the line.

See the STVM® Washdown Station for information on our complete station.

Typical Applications

EcoFlow® Water Conserving Seal Support System

Operation

The EcoFlow® mechanical seal support system contains a highly reliable and repeatable thermal actuator that continuously senses the seal water temperature. If the seal water should exceed the specified factory set-point the valve will modulate open discharging the hot water, displacing it with cool water. This cooler water will cause the EcoFlow® to modulate closed. This cycle will continue to occur as long as excessive heat is being transferred to the seal water causing the water temperature to exceed the valve’s factory set-point.

Typical Applications

The EcoFlow® valve is installed on the seal water outlet of a mechanical seal to continuously maintain a constant seal water outlet temperature. This increases seal life by ensuring an optimum seal environment while drastically reducing water consumption and significantly increasing cost savings.

  • Self-operating – no external power source required
  • Drastically decreases seal water consumption
  • Increases water treatment efficiency
  • Eliminates dry runs due to operator error
  • Increases seal life
  • Expands mechanical seal use to more applications
  • Decreases operating cost
  • Quick and easy installation

Seal Water Savings Example

To illustrate the water savings from the case study below that can be realized with EcoFlow®’s mechanical seal support system, we’ve used a typical seal manufacturer’s recommendation of 2.6 GPM to be used to flush the seals versus EcoFlow’s 0.05 GPM, operating 8 hours a day, 5 days a week (2080 hours per year).

Recommended: 2080 hours x 2.6 gallons per minute x 60 minutes = 324,480 gallons of water per year.
W/ EcoFlow: 2080 hours x 0.05 gallons per minute x 60 minutes = 6,240 gallons of water per year.

In our calculation, EcoFlow® can save ~318,000 gallons of water per year.

3/4″ GURU PC® Passenger Rail Car Freeze Protection

Operation

The ¾” thermostatic GURU PC®  valve is installed at the lowest point within the potable water-bearing system on a passenger train car to prevent the water from freezing when the car heat is turned off.

This self-operating freeze protection valve monitors ambient temperatures. It will automatically drain the passenger train car’s water tanks if the outside air temperature falls to the valve’s set-point, 35°F (1.7°C), ultimately preventing a system freeze up and thousands of dollars in damage.

Once power and heat are restored to the rail car, the valve will warm up and modulate closed, allowing the water tanks to be refilled before returning to service. Since the valve is completely mechanical, no electrical or air connections are required to operate.

We recommend using our electric heater assembly to avoid delays in refilling the potable water system and getting the car back into service after a valve activation. The heater attaches to the thermal actuator on the valve and will warm it up quickly once power is restored. This allows the valve to close instantly and the system to be refilled as quickly as possible after a drain occurrence.

To help prevent nuisance dumping, we recommend replacing the cartridge assembly approximately every 2 years if sluggish or marginal closing performance from testing is witnessed. We offer a replacement cartridge kit to assist ease of replacement without removal of the Tee Body.

The GURU PC® is NSF 61 Certified for use in potable water systems and shock and vibration tested to withstand harsh conditions. Compact, reliable, and in-line serviceable for ease of maintenance, the GURU PC® is the ideal solution to protect your passenger train toilet modules and galleys from freeze damage.

Therm-O-Mix® Tepid Water Delivery Station

Operation

The Therm-O-Mix® is designed to supply tepid water delivery for one shower/eyewash combo at a time. This water heating system should be installed near the shower and piped into a facility’s steam and cold water supply lines.

When an emergency shower or eyewash is activated, the pressure drop on a diaphragm opens the steam control valve (V-3). Water and steam flow are established, instantly heating the water and condensing the steam. After exiting the heat exchanger, the hot water enters the tempering valve (V-5) and then the mixing valve (V-1), where it is blended with cold water to produce an outlet of 80°F water. The steam valve remains closed should the water supply be interrupted.

Typical Applications

OSHA and ANSI require all your emergency fixtures to provide tepid water for a minimum & continuous 15-minute cycle. Tepid is defined to be between 60°F (16°C) and 100°F (38°C). The Therm-O-Mix® Tepid Water Delivery System can ensure your emergency equipment will meet these code requirements by providing 80°F water to protect personnel from scalding or freezing temperature. Since the station does not require any electric power, it is suitable for explosion-proof environments and outdoor installations.

Design Features

  • Exclusive self-actuating Thermoloid® wax blend thermal actuator
  • Plant steam and water never mix – uses a compact heat exchanger
  • Standard pressure unit available for 45-60 PSIG steam pressure
  • Low-pressure unit available for 15-30 PSIG steam pressure
