COOLING SySTEM
In order to avoid a moisture condensation the following possibilities can be done. The
application of both methods is recommended.
Supply of temper coolant
This is possible by using heatings in the cooling circuit for the control of the coolant tem-
perature. The following dew point table is available for this:
Coolant inlet temperature is depending on ambient temperature and air humidity:

Table 19: Supply of temper coolant
Temperature control
The cooling system can be connected by means of pneumatic or magnetic valves. A re-
lay is frontend. In order to avoid pressure surges, the valves for the temperature control
must be inserted in the flow line of the cooling circuit. All usual valves can be used. Pay
attention that the valves are faultless and do not clamp.
Emptying the cooling circuit
If a system shall be switched off for a longer period, the cooling circuit must be drained
completely. In the case of temperatures below 0°C, the cooling circuit must be blown out
additionally with compressed air.
