Water is mainly used as coolant in injection molding. It is required as cold and hot water.
If a cooling device is not connected to an external water supply, but creates cold water through an internal module, the device is called autarkic temperature control.
In this case of self-sufficient temperature control, both the water replenishment and the cooling take place independently of an on-site cooling network.
Mostly mobile, the cooling and temperature control unit can be matched in its performance to the production process and stands next to the machine(s).
