■ Application

It is mainly applicable to long time cooling or heating of moulds, also suitable for patterns in which mould long heating shifts to cooling and vice versa.

Working Principle

When the system needs to be heated up, solenoid valve 2 and 3 close and solenoid valve 3 opens, heaters quickly heat up the system to required temperature. Then P.I.D. controller maintains the water tempera¬ture by controlling solenoid valve 2. And when the system needs to be cooled, solenoid valve 2 and 3 opens, the temperature drops to the required temperature with the effects of chilled water in water tank. Quick heating and cooling can be achieved through solenoid valve controlling.
