shown in the diagrams. Please note the significance
of the shaded areas. Thresholds should not be selected as
design or continuous operation points.
- 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 threshold.
F or 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!
