3 | Areas of application
The compressors are factory-lled with the following oil type:
- for R134a, R404A/R507, R407C FUCHS Reniso Triton SE 55
- for 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. FKX30/325 N).
3.1 Refrigerants
• HFKW / HFC: R134a, R404A/R507, R407C
• (H)FCKW / (H)CFC: R22
3.2 Oil charge
ATTENTION Compressor operation is possible within the limits of application

areas. The limits of application must be observed. Thresholds
should not be selected as design or continuous operating points.

Avoid continuous operation near the threshold. Should the com-
pressor happen to be used near the thresholds, we recommend the
useofathermalprotectionthermostat(Accessories,Chap.7).
When operating in the vacuum range, there is a danger of air en-
tering 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!
