3.3.3 Environmental Issues

Environmentally concious and anticipatory behaviour of staff avoids environmentally hazardous impacts.
The following principles apply for environmentally conscious behaviour:
 Environmentally hazardous substances must not get into the soil or into the drains. They should be
kept in appropriate containers.

3.4.1 Safety and Signalling Equipment included in the Unit

The unit is equipped with safety equipment at critical spots:
 The filling level of the coolant container is indicated in an inspection glass.
 The circulated oil amount is controlled by a flow control device (flow switch) that must be integrated in
the potential-free safety circuit of the device that is to be cooled.
 The oil temperature is controlled by a thermostat. When the oil temperature exceeds the maximum
setpoint this is indicated by the potential-free safety circuit.
 The maximum pump pressure is limited by an angle-type safety valve that bypasses the oil stream
when the pressure pre-set is exceeded.
