Download Datasheet

Mokon's Duratherm HTP circulating water temperature control system maximizes performance with temperatures up to 300°F (149°C) and pressures up to 70 PSI. Designed for restrictive processes or those requiring higher fluid temperature or pressure, the HTP system adds a cast iron pump to the Duratherm design, resulting in high temperature and pressure capabilities.

All Duratherm systems meet NFPA 79 (National Fire Protection Association) electrical safety standards and come standard with a UL 508A labeled electrical sub-panel. All of these features and more, combined with our extended warranty, make the Duratherm an easy choice for delivering precise and accurate temperature control.
