Water Systems

Duratherm MAX

Mokon's Duratherm MAX circulating water temperature control system maximizes performance with temperatures up to 380°F (193°C) and system pressures up to 300 PSI (20.7 BAR). The Duratherm MAX is ideal for restrictive processes and high temperature water applications.

This Duratherm design features a stainless steel heater vessel that is designed and tested to ASME standards. The system utilizes nonferrous and stainless steel materials of construction and a seal-less magnetic drive turbine pump fitted with a stainless steel impeller (D4 Series) or an end suction centrifugal pump (D3 Series). The Duratherm MAX utilizes an inline heat exchanger that provides safe and dependable cooling of the process fluid and eliminates thermal shock, flashing to steam, mineral buildup and expansion noise.
