ThermOmegaTech’s line of GURU PC® freeze protection valves are self-operating, thermostatic drain valves that protect potable water-bearing systems on passenger cars from freezing which in turn protects your investment and keeps your equipment safe.

During normal operation, a passenger car’s heating warms the water system, typically supplying on board toilets and kitchens. However, when the heat is turned off for switching locomotives, during layovers or a power outage the temperature inside of the cabin can quickly fall towards freezing. If the water in the system is not heated or drained it will eventually freeze and potentially cause a lot of damage.

The GURU PC® ¾” and 1″ valves monitor ambient temperatures and will automatically drain the water tanks if the air temperature falls to the valve’s set-point, 35°F, preventing burst piping and frozen tanks. Completely mechanical, with no outside power required, its high flow design allows for rapid draining, eliminating costly freeze damage.

Once power has been restored to the train, ThermOmegaTech® recommends using their electric heater assembly to quickly refill the water system and get the car back into service as soon as possible.

The advanced, reliable GURU PC® valves increase uptime on passenger cars by preventing water lines from freezing before any damage can occur.
