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.
- 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.
Avoid continuous operation near the threshold.
For operation with supplementary cooling:
- Use only oils with high thermal stability.
For operation with capacity regulator:
- Continuous operation, when the capacity regulator is activated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in
the system can not under certain circumstances ensure that
sufcient oil is transported back to the compressor.
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!
