Keeps Production Up and Running
Even a minor circuit leak from stress cracks or bad O-rings can stop operations, but with the Mokon HTF NPS Series positive and negative pressure temperature control system, you can finish the production run without the nuisance of a leak or the costly interruption of a repair.

Whether your process requires positive pressure (no leaks present) or negative pressure (to stop a leak), HTF NPS Series provides the most efficient means of temperature control. By incorporationg a venturi jet pump and a uniquely designed reservoir, you are provided with a self-supporting means of accurate temperature control up to 400°F (204°C) in a positive or negative pressure condition.

Easy to Use
Designed to be used in the same manner as our Duratherm NPS water system, the system requires no special piping, hoses or utilities. By simply moving a three-way flow control valve on the back of the cabinet, the system is changed from a positive pressure to a negative pressure system in an instant. The system's reservoir acts as a fluid supply source and air separation device, making the venting of the system automatic.

Easily removable cabinet panels provide access to internal components, making routine maintenance and adjustments simple and fast.

"Negative" Benefits

Being negative isn't always a bad thing.

With Mokon's HTF NPS Series, negative pressure creates a vacuum, essentially pulling air and oil out of the mold instead of pushing it through the system. There are many benefits with this method, including:

  • Repairs can be deferred until a more convenient time.
  • The risk of hot fluid spray is reduced, improving worker safety.
  • Less downtime means manpower and equipment are maximized, increasing productivity.

* Please consult factory for more information.

  • 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.
