With a Built-In Water Tank (Closed Loop)
The built-in circulation pump pumps liquid from the water tank and then through the cooling unit (heat exchanger). There, the liquid is cooled and then returns to the tank. This cycle is repeated and the liquid is continuously cooled until it reaches the desired set temperature, at which time the cooling unit temperature regulator shuts off the cooler. If the liquid temperature rises above the set control value, then the cooler is automatically started again. In this way, the temperature of the liquid is maintained and is pumped out via the discharge pump.
※ In addition to the discharge pump, models with built-in circulation pumps are also available. Please refer to the specifications of individual models for further details.
