Water Systems


Mokon's Hydrotherm circulating water temperature control system is engineered to improve accuracy, reliability of operation and increase output. The Hydrotherm has the highest quality components and construction materials in the industry with non-ferrous and stainless steel piping and connections, which do not rust or contaminate water.

The Hydrotherm surpasses all competitive systems by providing stainless steel as the main component for wetted surfaces. Where many of our competitors supply carbon steel and cast iron systems, only Mokon provides the Hydrotherm with stainless steel components including a stainless steel pump, housing, impeller, heater canister and pump suction manifold.

All Hydrotherm systems come standard with a cULus 508A labeled electrical sub-panel. All of these features and more, combined with our extended warranty, make the Hydrotherm an easy choice for delivering precise and accurate temperature control.

Additional Features:
  • 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 Hydrotherm 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

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.
