3|Areas of application
The compressors are factory-lled with the following oil type:
- FUCHS Reniso Triton SE 55
Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an X in the type
designation (e.g. HGX34P/380-2 A).
3.1 Refrigerants
• HFKW / HFC: R134a, R407C
3.2 Oil charge
INFO For refilling, we recommend the above oil types.
Alternatives: see lubricants table, Chapter 7.5.
ATTENTION Compressor operation is possible within the operating limits
showninthediagrams.Pleasenotethesignicance
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.permissibleswitchingfrequency8x/h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
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
systemcannotundercertaincircumstancesensurethatsufci-
ent oil is transported back to the compressor.
Foroperationwithfrequencyconverter:
- Control range of the compressor 15 - 50 Hz
(K Design 15 - 60 Hz).
- The maximum current and power consumption must not be
exceeded.Inthecaseofoperationabovethemainsfrequency,
the application limit can therefore be limited
- Use a heat protection thermostat.
- Oilreturnatlowfrequencymustbesupplied.
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!
3.3 Limits of application
ATTENTION The oil level must be in the
visible part of the sight glass;
damage to the compressor is
possible if overfilled or under-
filled!
