Extend compressor lifetime and save energy with drive control
Screw compressors controlled by a variable frequency drive (VFD) typically use 15% less energy than traditional screw compressors with slide valve control only.
Optimized start/stop cycles reduce wear and tear on the compressor. Drive-controlled reciprocating and scroll compressors have higher COP at part loads. VLT® drives are particularly suitable for controlling scroll compressors.
Danfoss Drives’ solutions for the marine and offshore industry have the highest number of class type approvals from nine authorities: DNV-GL, ABS, Bureau Veritas, Korean Register, CCS, RINA, Lloyds Register, RMRS and Class NK.
This gives you the best possible choice when selecting drives for your marine application.
