Mokon's Minitherm circulating water temperature control system is designed to surpass today's safety standards, while providing accurate control of your process temperature. The Minitherm's compact package fits into tight spaces reducing floor space requirements and is ideal for small tonnage molding machine and lab applications.

The Minitherm is available in 10 GPM pumping capacity and heating capacities of 2 or 4 kW, for operation up to 250°F (121°C). Each Mokon Minitherm is equipped with a non-proprietary microprocessor-based PID controller to ensure accurate control, a horizontally mounted inline cast brass heater manifold for faster heat up and cool down providing high energy efficiency, and non-ferrous piping and components that do not rust or contaminate water.

All Minitherm systems come standard with a UL 508A labeled electrical sub-panel. All of these features and more, combined with our extended warranty, make the Minitherm 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

Eurotherm 3216

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.
