Compressor functions
VSH compressors are equipped with an oil injec-
tion system that ensures the scroll set lubrica-
tion and controls the oil circulation ratio, at all
running speeds. The frequency converter via an
oil injection valve controls this system. The oil
injection valve is a normally closed valve. At low
speed, the valve is closed and the oil is injected
below the orbiting scroll.
Optimal bearings lubrication is ensured by a
gerotor oil pump at all compressor speeds.

The compressors are delivered with 230V coils.
24V coils are available as accessory (see accesso-
ries page at the end of this document).
Control parameters are factory preset but acces-
sible on the parameter list as read only values.
