ThermOmegaTech: Passenger Car Freeze Protection - Guru PC Valves

The GURU PC® valve is installed at the lowest point in a passenger rail car's potable water-bearing system to prevent freezing when the cabin heat is turned off. This thermostatic valve monitors ambient temperatures and automatically opens and drains the system if the air temperature falls to the valve's 35°F(1.6°C) set-point, preventing frozen tanks and pipes.To avoid a delay in getting the car back into service after a valve activation, ThermOmegaTech® recommends using our electric heater assembly in conjunction with the valve. The heater assembly attaches to the thermal actuator to quickly heat up and close the valve once power is restored. This allows for the water system to be refilled and the car returned to service promptly.
