Areas of application
ATTENTION! Compressor operation is possible within the operating limits
shown in the diagrams. Thresholds should not be selected as
design or continuous operation points.
- Max. permissible ambient temperature 45°C
- Max. permissible discharge end temperature 160°C.
- Max. permissible switching frequency 12x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
