3| Areas of application
The compressors are factory-filled 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. HG
X34P/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
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 capacity regulator:
- The suction gas superheat temperature may need to be reduced
circumstances, individual setting required.
- Oil return must be supplied.
For operation with frequency converter:
- Control range of the compressor 15 - 50 Hz
(K Design 15 - 60 Hz).
- 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
- Use a heat protection thermostat.
- Operate no additional capacity controllers.
- Oil return at low frequency must be supplied.
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!
