Areas of application
The compressors are filled at the factory with the following oil type:
- for R134a, R404A/R507, R407C, R513A
BOCK
lub E55
Compressors with ester oil charge (
BOCK
lub E55
) are marked with an X in the type
designation (e.g. HG
X
22e/190-4 A).
3.1 Refrigerants
• HFKW / HFC:
R134a, R404A/R507, R407C, R513A
3.2 Oil charge
INFO!
For refilling, we recommend the above oil types.
Alternatives: see chapter 7.4
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!
ATTENTION!

ATTENTION! Compressor operation is possible within the operating limits.
These can be found in Bock compressor selection tool (VAP)
under vap.bock.de. Observe the information given there.
- Permissible ambient temperature (-20°C) - (+60°C)
- Max. permissible discharge end temperature 140°C.
- Max. permissible switching frequency 8x /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 limits.
For operation with frequency converter:
- The potential control range of the compressor is 30-70 Hz.
- Max. permissible current consumption must not be exceeded.
At max. rotation speed therefore, the application limit can
be reduced.
- Use a thermal protection thermostat.
- Do not operate an additional capacity controller.
- Oil return at low frequency must be guaranteed.
