Download Datasheet

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. The Duratherm MAX incorporates a unique fan-cooled heat exchanger that provides safe and dependable cooling of the process fluid and eliminates thermal shock, flashing to steam, mineral buildup and expansion noise.

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 3200 Series

The Eurotherm 1/8 DIN 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 controllers available with high/low deviation alarm, remote setpoint and retransmission, and serial communciation. A three-year warranty comes standard with the controller.
