Download Datasheet

Mokon's HTF ST Series heat transfer fluid system maximizes performance with temperatures from 125°F to 700°F (52°C to 371°C). The ST Series is a stationary system providing greater performance with higher flow and heating capacities. Mokon oil systems offer many advantages when using heat transfer fluids over steam including cost savings, lower operating pressures, greater energy efficiency, and safer operation.

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.
