Mokon's Dual Zone Duratherm circulating water temperature control system provides two independent zones of control from one location in a sleek, vertical design without increasing the amount of floor space required for operation.

The Dual Zone Duratherm is built with an advanced heating canister design and nonferrous materials of construction which provide unsurpassed corrosion resistance, including a stainless steel pump, housing, impeller, and shaft. The number of piping connections is reduced to ensure leak-free operation.

All Duratherm systems meet NFPA 79 (National Fire Protection Association) electrical safety standards and come standard with a UL 508A labeled electrical sub-panel. All of these features and more, combined with our extended warranty, make the Duratherm an easy choice for delivering precise and accurate temperature control.

Additional Features:
  • NFPA 79 electrical safety standards
  • UL 508A labeled electrical sub-panel
  • Sleek, vertical space-saving design
  • Extended warranty:
    • 3 years on system
    • 5 years on microprocessor controller and safeties
    • Lifetime on seals, piping and canister
  • Unique stainless steel heating canister design: (shown below)

The Duratherm design features an advanced heating canister with stainless steel diverter, which generates a forced flow path over the heating elements for higher velocity and maximum turbulence - increasing heat transfer to improve efficiency and reduce scale build-up that can cause heater burn-out. This unique design provides customers unmatched control efficiency and accuracy, less down time and lower operating costs.

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.
