Areas of application
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.
- 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.
With enterprise with output regulator:
- in the frontier sometimes reduction and/or individual attitude
of the suction gas overheating necessarily.
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.
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!
The compressors are filled at the factory with the following oil type:
- for R404A/R507, R410A
FUCHS Reniso Triton SE 55
- for R22
FUCHS Reniso SP 46
Compressors with ester oil filling (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
• HFC :

3.3 Limits of application
INFO!
For refilling, we recommend the above oil types.
Alternatives:
see lubricants table, Chapter 8.5.
The oil level must be in the visible
part of the sight glass; damage
to the compressor is possible if
overfilled or underfilled!
