About Us

For over 35 years, ThermOmegaTech® has been a leader in the design and manufacture of self-actuating thermostatic temperature control technology. ThermOmegaTech serves a multitude of industries and, as a result, creates solutions for a wide-range of applications.

As the developers of highly-reliable and cost effective freeze valves for the railroad industry in 1983, ThermOmegaTech now provides the standard in freeze protection valves for this industry and now takes pride in protecting billions of dollars of equipment every year.

In addition to solutions for the railroad industry, ThermOmegaTech’s valve technology is used in Commercial PlumbingAerospace & Defense, and Industrial applications where temperature control is critical.

These include freeze protection, scald protection, steam traps, steam tracing, thermal relief, mixing & diverting, cooling fluid control, thermal bypass, balancing, drain tempering, tepid water delivery, and many other applications where ambient, fluid, or surface temperatures affect a system.

Our mixing valves designs for both hot/cold water and steam/water applications have been incorporated into Washdown Stations for industrial cleaning and Instantaneous Hot Water Heaters and Tepid Water Delivery Systems for safety showers and combination face/eyewash stations.

ThermOmegaTech is vertically integrated – designing, machining, assembling and testing/inspecting over 95% of our products on-site which allows us to communicate quickly and efficiently through every step of the product development cycle.

ThermOmegaTech-Machine-ShopOur state-of-the-art product facility is equipped with a dozen CNC turning and milling centers, 3 environmental chambers, 18 aqueous & hi-temp oil test baths, and a CMM machine to meet our customers’ time, cost, quality and technical performance requirements.


We offer custom design and manufacturing of self-actuated temperature control solutions, customized engineering and fabrication services to meet your projects specific needs while ensuring rapid-responses and an individualized customer service experience.


ThermOmegaTech is a privately held company with 40,000 square feet of manufacturing and office facility, located about an hour outside of Philadelphia in Warminster, PA. We want our facility to be a great place for our people and for the environment which is why it’s 75% powered by rooftop solar panels to help in reducing greenhouse gas (GHG) emissions.
