Cooling Circuit
In the cooling circuit the coolant is driven by the pump to the device that is to be cooled and back via
the return flow. The heat is dissipated into the ambient air by an air-cooled heat exchanger.
Exceedance of the maximum pump pressure is prevented by a by-pass circuit.
The water temperature is controlled by an electric thermostat, whereas water throughput is controlled
by a flow control device. Both indications are made potential-free and must be integrated into the
safety circuit of the device to be cooled.
