Compressor specifications
For dedicated variable speed drive specifications,
refer to “Danfoss VRJ Installation and Operation
instructions”.
A specific oil pump ensures optimal bearing
lubrication at all compressor speeds. This to have
sufficient bearing lubrication at low speeds as well
as avoid excessive Oil Circulation Ratio (OCR) at
high speeds.
