Areas of application
The compressors are filled at the factory with the following oil type:
- für R404A/R507, R410A, R448A/R449A
FUCHS Reniso Triton SE 55
- für R22
FUCHS Reniso SP 46
Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an
X
in the type
designation (e.g. HGZ
X
7/2110-4 R404A).
3.1 Refrigerants
• HFKW :
R404A/R507, R410A, R448A/R449A
• (H)FCKW:
R22
3.2 Oil charge
INFO
For refilling, we recommend the above oil types.
Alternatives: see lubricants table, Chapter 8.5.
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 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.
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!
