Troublesome cooling circuit leaks in processes can result in serious production losses. The leaks may be due to small stress cracks, which leak under pressure. Our Positive/Negative Pressure TCU uses a liquid venturi to draw cooling water through the mold under negative pressure.

Precise temperature control is provided by the operation of a solid state or microprocessor controller, which activates a heater or a cooling water solenoid as required.
