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. HGX4/650-4 R134a).

or continuous operation points.

- 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.
 For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.

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
The oil level must be in the
visible part of the sight
glass; damage to the com-
pressor is possible if over-
filled or underfilled!
