STVM Washdown Station FAQs

The ThermOmegaTech® STVM® Washdown Station utilizes a silent type venture mixing valve to combine steam and water together to produce a user-defined temperature. This ingeniously designed product is efficient, easy to maintain, and most importantly safe – a necessary addition to any facility that uses washdown stations.

Designed to have a quick startup time and an even shorter downtime, the STVM® features an interchangeable cartridge for ease of maintenance. Unlike other manufacturers’ washdown stations that require a specialized tool and the user to take the unit off the wall to perform regular maintenance, ThermOmegaTech® STVM® Washdown Station requires only a standard wrench and doesn’t need to be moved from its point of installation. Simply unscrew the cartridge from the top of the unit, put in a new cartridge, and the unit is up and running within moments.

As the STVM unit uses steam to heat water, personnel safety is a top priority. If the cold-water supply to the unit is interrupted the thermostatic mixing valve will sense the over-temperature flow and close off, preventing operation. The valve will remain closed until the cold water supply is restored, after which it will automatically open and re-establish flow, protecting both personnel and equipment.

Q: What is the difference between a 150°F unit and a 185°F unit?
A: These numbers indicate the unit’s over-temperature shutoff point, typically due to a sudden lack of a cold-water supply. Once the unit’s thermostatic actuator senses its set shut-off temperature (either 150°F or 185°F, depending on the model) the internal mixing valve will modulate closed and stop the flow. Only after the cold-water supply has been restored to the unit will the valve modulate open and re-establish flow. The unit’s over-temperature shutoff point is not field adjustable.

Q: How can we make the unit’s downtime for maintenance even shorter?
A: Keep a spare cartridge on hand! Don’t wait for the STVM® Washdown Station to require maintenance to order a new cartridge as the lead time will result in the unit being out of service until the new cartridge is received. By keeping a spare cartridge on hand the station’s downtime is minimized, allowing personnel to get back to work sooner.

A Washdown Station For Every Application

It is critical to have a washdown station in food processing, dairy, breweries, wineries, chemical, petrochemical, and pharmaceutical facilities to maintain a clean environment. Washdown stations are used to quickly and efficiently clean and sanitize equipment in place between production runs or shift changes.

ThermOmegaTech® offers three different washdown station options:

STVM® Steam & Water Station

The STVM® Washdown Station provides an effective high temperature wash in an easy-to-maintain package. Utilizing our patented Silent Venturi Mixing Valve (STVM®) technology, this washdown station mixes together steam and water to produce a high-powered wash at a user-defined temperature.

Designed to be self-scouring, the mixing valve prevents mineral buildup in tight spaces, decreasing maintenance frequency. To further reduce time spent on required regular maintenance, the unit is in-line serviceable. The user simply switches out the STVM® cartridge with another and the unit is back up and running in minutes.

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.

HCX Water & Water Station

For facilities without an available steam supply, the HCX Station is an ideal solution. This unit utilizes individual globe valves to mix hot and cold water to a user-defined temperature, clearly displayed on the integrated temperature display gauge.

To prevent accidental scalding, the unit is offered with our unique SmartFlow feature. This in-line, over-temperature safety valve automatically stops flow should the unit’s output exceed a factory specified set-point.

HCS Single-Channel Station

The HCS Station simplifies washdown applications even further, providing a high-powered single stream of either cold water or pre-heated hot water at the turn of a ball valve. The unit employs an integrated temperature gauge to confirm output temperature.
