filled or underfilled!
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
- M ax. 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 threshold.
For operation with frequency converter:
- The potential control range of the compressor is 25-70 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.
- O il return at low frequency must be guaranteed.
- C onsultation with Bock.
