Winterize Your Passenger Cars
& Locomotives

Winterizing your fleet is crucial—if your water tanks are not adequately protected, freezing temperatures can lead to thousands in repair costs. When the water in a diesel-electric locomotive's cooling system or a passenger car’s potable water system freezes, it can result in burst pipes, damaged equipment, and costly delays.

For over 40 years, ThermOmegaTech^® has been a leader in designing and manufacturing thermostatic valves and actuators, protecting critical rail systems from freezing temperatures. Since 1983, we have set the standard with our GURU^® Plug, a self-actuating valve that protects locomotives from freeze damage. Today, we are the North American Market Leader in Railroad Freeze Protection.

The GURU^® DL2.1 Plug protects the diesel locomotives’ water-cooling systems from freezing when the engine is off. This self-actuating valve continuously monitors the cooling system's temperature and snaps open to rapidly drain the system when the water temperature reaches the valve's set point. Resetting the GURU® Plug is easy — reheat the cartridge and reinsert it into the hex nut.

For passenger cars, the GURU PC^® valve protects water systems that supply toilets and galleys from freezing when the car heat is turned off during a layover or locomotive switch. This valve responds to ambient temperatures, automatically modulating open to drain the water tanks if the external temperature drops to the valve's set point. Once power and heat are restored to the rail car, the valve closes, allowing the tanks to be refilled before the car returns to service.

ThermOmegaTech^® valves are completely mechanical and require no electricity, making them ideal for any situation, even during power outages.
