3| Areas of application

3.1 Refrigerants

• HFKW / HFC: R134a

3.2 Oil charge

The compressors are filled at the factory 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. HGX6/1410-4 R134a).

INFO!
For refilling, we recommend the above oil types.
Alternatives: see lubricants table, Chapter 7.5.
ATTENTION! The oil level must be in the visible
part of the sight glass; damage
to the compressor is possible if
overfilled 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
- M ax. permissible switching frequency 12x /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:
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
F or 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.
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!
