Less problems with duty cycle
Cold start at -50°C possible without preheat
Almost maintenance-free, much lower
LCC
Less complex system/ fewer interfaces
(no oil filter, no condensate collector)
Very low noise level and vibrations
Reduced space envelope/ weight
Modular design (communal spares, …)

Recommended DC oil lubricated compressors >30%
At low DC´s condensate falls out in the crankcase (temperature changing's)
This reduced the lifetime of oil lubricated compressors,
secondary damages are possible!
