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.
These can be found in Bock compressor selection tool (VAP) under
vap.bock.de. Observe the information given there.
- 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!
