GURU^® Plug Rebuild Program
Return. Refurbish. Reuse.

ThermOmegaTech^®, an industry leader in thermostatic self-actuating valves for over 35 years, designs and manufactures the GURU^® Plug. A reliable and compact freeze protection valve for locomotives and passenger cars, the GURU^® Plug protects critical rail equipment from cold weather.

The GURU^® Plug is a water-sensing, self-operating, thermostatic drain valve that responds to engine coolant temperature. When a locomotive is shut down and cooling water reaches the set point of the valve (35^°F or 40^°F/1.7^°C or 4.5^°C), the plug opens and drains the locomotive's cooling system before any freeze damage occurs.

To keep the GURU^® Plug functioning at peak performance, ThermOmegaTech^® recommends replacing them every 18-24 months to avoid nuisance dumping above the valve’s setpoint as the valve ages.

An innovator in freeze protection, ThermOmegaTech^®'s GURU^®s are the North American Railroad standard for protecting locomotives. Each year, GURU^® technology protects billions of dollars in rail equipment from costly freeze damage and lengthy repairs. The rebuild program is designed to clean, refurbish, test, and return used GURU^® plugs to full operation.

During the rebuild process, the plug is completely disassembled and checked. Interior components are replaced, and the refurbished valve goes through three tests to ensure full functionality before being returned to the customer: cartridge test, leak test, and pop test.

The program will be operated out of ThermOmegaTech^®'s company headquarters and manufacturing facility in Warminster, PA USA where the valves were originally assembled, tested, and distributed to their end users. GURU PC^® valves, used to protect passenger cars from freeze damage, are also eligible for the GURU^® Rebuild Program.
