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. HGX22e/190-4 A).

filled 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 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 limits.
For operation with frequency converter:
- The potential control range of the compressor is 30-70 Hz.
- Max. permissible current consumption must not be exceeded.
At max. rotation speed therefore, the application limit can
be reduced.
- Use a thermal protection thermostat.
- Do not operate an additional capacity controller.
- Oil return at low frequency must be guaranteed.
- Consultation with GEA.
W hen operating in the vacuum range, there is a danger of air
e ntering 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!
