Download Datasheet

Mokon's HTF 600 Series heat transfer oil systems are designed to meet the high temperature demands of controlling process temperatures up to 600°F (315°C) with an option to go to 650°F (343°C) . Offered with a pumping capacity of 20 GPM; single, dual, or triple zone configurations; and varying heating capacities, Mokon can match a system to meet your temperature control processing requirements. These systems feature the latest control technology, unique design philosophies, and unmatched electrical/safety standards to ensure precise process fluid temperature control.

Unique Heating Design Maximizes Energy Efficiency

  • Smaller hold-up volume of fluid results in faster heat up and cool down
  • Longer heater and fluid life - unique flow pattern design and low watt density elements

Cool Oil Reservoir Design

  • Separate cool oil reservoir isolates heating loop from cooling loop
  • Continuous flow direct immersion heat exchanger eliminates thermal shock
  • Reduces oxidation rate or breakdown of fluid in cool oil reservoir
  • Only system designed to hold fluid in lower reservoir so fluid does not spill onto floor in event of a leak

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.
