Supply of temper coolant
This is possible by using heatings in the cooling circuit for the control of the coolant temper-
ature. The following dew point table is available for this:
Coolant inlet temperature [°C] is depending on ambient temperature and air humidity

Temperature control
The cooling system can be connected by means of pneumatic or magnetic valves. A relay is
frontend. In order to avoid pressure surges, the valves for the temperature control must be
insertedintheowlineofthecoolingcircuit.Allusualvalvescanbeused.Payattentionthat
thevalvesarefaultlessanddonotclamp.Monitoringofthesystemispossiblewithaow
monitor.
