Duratherm HTP

Mokon's Duratherm HTP circulating water temperature control system maximizes performance with temperatures up to 300°F (149°C) with a required water pressure of 60 PSI. Designed for restrictive processes or those requiring higher fluid temperature or pressure, the HTP system adds a stainless steel pump to the Duratherm design, resulting in high temperature and pressure capabilities.

All Duratherm systems come standard with a cULus 508A labeled electrical sub-panel. All these features and more, combined with our extended warranty, make the Duratherm an easy choice for delivering precise and accurate temperature control.

Features of Standard and Optional Controls

A variety of controls are available from Mokon to enhance the high performance of our systems. From solid state to microprocessor based, with communication capabilities to PLC type controls, Mokon can provide the type of control package right for your process.


Eurotherm 3216 Series

The Eurotherm 1/16 DIN (3216) microprocessor controller is operator friendly and easy-to-use. Standard features include a microprocessor PID controller for the highest accuracy in temperature control, a dual LCD display that shows set point and actual fluid temperature, and scrolling text messages that deliver plain language messages to let users know exactly what is happening to the process. There are optional 1/8 or 1/4 DIN controllers available, with high/low deviation alarm, remote set point and retransmission and serial communication. A five-year warranty comes standard with the controller.
