Request Information
For higher rated pressure systems, the HAT/RA-HP thermal relief valve is used to continuously sense fluid temperature and modulate open to discharge fluid when it is above the valve's set point. Once outlet temperature cools below the set point, the valve modulates toward its closed position to reduce flow.

 N/A Thermal Relief for Pumps

Thermal relief is needed to regulate the flow of glycol, water, or any other media that flows through high-pressure pumps to remove heat from equipment or a process, essentially protecting the pump and pump seals from over-temperature damage and scalding incidents.

The Need

Pumps are typically used for a variety of applications, from residential homes and commercial buildings to industrial appliances or equipment to provide water pressure. For example, buildings with several floors sometimes struggle with inadequate water flow reaching the higher levels, therefore, a booster pump is installed to supply water at an elevated pressure to distribute flow to those levels. However, if the water demand in the building is less than the maximum demand, the pump will continue to run on an inefficient portion of its performance curve and this excess pump energy goes into heating the water inside the pump.

When high temperature water inside the pump is released through faucets, showers, or any other water supply, users can be at risk of scalding. For this reason, temperature in pumps need to be monitored and controlled constantly to avoid high-temperature damage.

The Solution

ThermOmegaTech® offers 100% mechanically operated thermal relief valves for booster pumps, fire pumps, and other high-pressure pumps to keep them cool during idling.

Thermal relief valves continuously monitor and control water temperature flowing through pumps, while discharging over-temperature water that can be collected, re-used, or re-purposed to eliminate waste.

All of ThermOmegaTech®’s valves are completely mechanical and require no electricity to operate. Our valves rely on automatic temperature monitoring to solve temperature problems ultimately saving time, water, and energy.
