ThermOmegaTech® Freeze Protection for Locomotives and Passenger Coaches

ThermOmegaTech® is an industry leader in freeze protection valves for passenger coaches and locomotives.

We design and manufacture advanced, reliable, and compact self-actuating valves for the railway industry.

Our high-quality control valve and freeze protection solutions are designed to protect critical rail equipment in adverse conditions.

Self-actuated temperature control valves

We demonstrate our leadership and commitment to producing high-quality temperature control solutions by:

  • Ensuring superior quality
  • Solving problems for our customers through innovative engineering and design
  • Bringing responsiveness, flexibility, and reliability to everything we do

We are industry leaders in innovative temperature control valve technology, and our decades of experience and knowledge are evident in our full suite of products and custom engineered solutions.

Freeze protection for locomotives

The GURU® Plug line of valves (GURU® DL2.1 CH & CHS, Magnum GURU®, and GURU® DL 2.1) are water-sensing, self-operating, thermostatic drain valves that respond to engine coolant temperature.

When the locomotive is shutdown and cooling water reaches the temperature set point of the valve (35°F or 40°F / 1.7°C or 4.5°C), the plug will snap open and drain the locomotive cooling system before any freeze damage occurs.

The Magnum GURU® Plug is a higher discharge capacity version of the standard GURU® Plug, providing a full 1.2in (30.48mm) bore to rapidly drain a locomotive.

Freeze protection for rail passenger coaches

The GURU PC® is a self-operating, thermostatic valve that automatically drains passenger coach water-bearing systems, typically for on-board restrooms and toilets, before freeze damage can occur.

Operating with no outside power, this self-modulating valve is designed to rapidly drain the system once an ambient temperature of 35°F (1.7°C) is detected. The valves are NSF 61/372 certified and shock and vibration tested by a third-party.

An optional heater assembly is available to rapidly heat and close the valve after it has drained the system, allowing the water to be refilled and for the passenger coach to get back into service promptly.

Only a standard 120VAC / 74VDC or 230VAC three-prong, grounded plug or wiring is needed, and no air connections are required.

Accessories for locomotive control valves

Additional tools are available to optimise the GURU® Plug’s performance.

The GURU® Flag and Clip tool prevents the GURU® Plug from dumping while refilling the locomotive’s cooling system after activation.

The magnetic GURU® Flag attaches to the outer wall of the locomotive to serve as a visible indicator that the valve is disarmed.

We recommend servicing the GURU® Plug every 18 to 24 months using the GURU® Rebuild Program in order to maintain optimal performance.
