As the North American Market Leader in Railroad Freeze Protection, ThermOmegaTech® has developed a variety of products for both locomotive and passenger cars.

The GURU® Plugs for locomotives have water sensing properties that causes it to snap open after the engine shuts down and the whole system begins to cool. This allows for the system to drain before freeze damage can occur.

ThermOmegaTech® offers additional tools to be used with the GURU® plugs on locomotives.
The GURU® Flag and Clip and GURU® Flag and Key tools allow the refilling of the locomotive cooling system with cold water without tripping the GURU® valves.
The Compressor head cleaning tool is used to flush dirt and other foreign matter from the water-cooled compressor heads. If left un-cleaned, the cooling jacket in the head can become completely blocked by foreign matter.

The GURU PC® valve is self-contained and drains water-bearing systems in passenger cars automatically by monitoring ambient temperatures. The valve is completely mechanical and requires no power connection of any kind. It is NSF 61/372 certified by a third party and shock & vibration tested by a third party.

The optional heater assembly is connected to available electric power to prevent draining when car heat is functioning normally. The heater quickly closes the valve for refilling after a drain and restoration of car power.
