Areas of application
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
- Permissible ambient temperature: (-20°C) - (+100°C)
- Max. permissible switching frequency: 12 x /h
- A minimum running time of 2 min. at equilibrium (continuous
operation) must be achieved.
Avoid continuous operation near the threshold. Should the
compressor happen to be used near the thresholds, we
recommend the use of a thermal protection thermostat
(Accessories, Chap. 7).
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 factory-filled with the following oil type:
- for R134a, R404A/R507, R407C
BOCK
lub E55
- for R22
BOCK
lub A46
Compressors with ester oil charge (
BOCK
lub E55
) are marked with an X in the type designation (e.g.
FK
X
20/170 N).
