4 | Areas of application
ATTENTION Compressor operation is possible within the operating limits.
These can be found in GEA Bock compressor selection tool (VAP)
under vap.gea.com. Observe the information given there.
- Permissible ambient temperature (-20°C) - (+60°C)
- Max. permissible discharge end temperature 140°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.
- Additional fans (accessories) can be used for additional cooling.
For operation with capacity regulator:
- Continuous operation, when the capacity regulator is activated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in the
system can not under certain circumstances ensure that suffi-
cient oil is transported back to the compressor.
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. Max. 60 Hz.
When operating in the vacuum range, there is a danger of air
entering on the suction side. This can cause chemical reactions,
a pressure rise in the condenser and an elevated compressed-gas
temperature. Prevent the ingress of air at all costs!
4.3 Limits of application
The compressors are filled at the factory with the following oil type:
- für R134a, R404A/R507, R407C, R407F FUCHS Reniso Triton SE 55
- für R22 FUCHS Reniso SP 46
Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an X in the type
designation (e.g. HG
X
66e/2070-4).
4.1 Refrigerants
• HFKW / HFC: R134a, R404A/R507, R407C, R407F • (H)FCKW / (H)CFC: R22

INFO
For refilling, we recommend the above oil types.
