3.2 Oil charge

The compressors are filled at the factory with the following oil type:
- for R134a, R404A/R507, R407C
- for R22
Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an X in the type
designation (e.g. HGX34e/380-4).

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 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 supplementary cooling:
- Use only oils with high thermal stability.
- Avoid continuous operation near the threshold.
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.
