4.7 Cooling of the machine
4.7.1 Continuous flow cooling (standard)
With fresh water cooling, water flows continuously through the cavity of the double walled compressor
housing.
For safety reasons, the cooling system is fitted with a solenoid valve, a temperature control and a safety
valve.
A special control unit and a thermostatic water valve are available optionally.
Temperature control
Monitors the temperature of the cooling water. Default mode: T
max
= 60 °C
Liquid level monitor
Monitors the filling level of the cooling water.
Safety valve
Protects from an incorrect operating pressure of the cooling water of > 6 bar.
Solenoid valve
It controls the cooling system. Control voltage: 24 V DC, normally closed
Dirt trap
Protects fittings and the cooling circuit from impurities in the incoming cooling water.
For connection of sensors see chapter 5.6.2 on page 23.
The operating instructions for the monitoring elements are enclosed with the machine.
