Areas of application
The compressors are filled at the factory with the following oil type:
GEA Bock C 85 E (only this oil may be used).
3.1 Refrigerants
•
CO

3.2 Oil charge
ATTENTION Property damage possible.
The oil level must be in the
visible part of the sight glass;
damage to the compressor
is possible if overfilled or
underfilled!

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.
- Permissible ambient temperature (-20°C) - (+60°C).
- Max. permissible discharge end temperature 160°C.
- Min. oil temperature
≥
30°C.
- Min. pressure gas temperature
≥
50°C.
- Max. permissible switching frequency 12x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with supplementary cooling
:
- Use only oils with high thermal stability.
- Avoid continuous operation near the threshold.
For operation with frequency converter:
- Frequency range 30-60 Hz.
- 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.
