Areas of application
ATTENTION! Compressor operation is possible within the operating limits
shown in the diagrams. Please note the significance
of the shaded areas. Thresholds should not be selected as design
or continuous operation points.
- Max. permissible discharge end temperature 140 °C
- Max. permissible switching frequency 8x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with frequency converter:
- The maximum current and power consumption must not be
exceeded. In the case of operation above the mains frequency,
the application limit can therefore be limited.
The compressors are filled at the factory with the following oil type:
Bock C 85 E (only this oil may be used)
