Oil Systems

Full Range

Mokon's heat transfer fluid (oil) based Full Range temperature control system maximizes performance with temperatures up to 650°F (343°C). The Full Range system offers a combination heating and cooling system all in one package. A Mokon oil system, combined with an Iceman chiller, integrates the benefits and features of both products into one compact, self-support unit.

The Full Range system is ideal for jacketed vessels, mixers and reactors; multi-zone processes; installations where rapid cooling is required; and laboratory, sanitary and chemical process applications.

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 set point and retransmission and serial communication. A five-year warranty comes standard with the controller.
