Supply of temper coolant
This is possible by using heatings in the cooling circuit for the control of the coolant tempera-
ture. The following dew point table is available for this:

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 flow line of the cooling circuit. All usual valves can be used. Pay attention that
the valves are faultless and do not clamp.
