Compressor

Compressor

Variable speed control of a compressor offers the ability to match the capacity to the actual need based on measurements in the system. Costs are reduced both through energy savings when running at lower speed, but also through lower installation costs caused by optimisation of the system and the compressor itself.

VLT® drives are designed to offer flexible, intelligent control of scroll, screw, piston and centrifugal compressors.
VLT® drives optimise control of compressors, reduce energy consumption and provide constant pressure regulation.

Fewer starts and stops will reduce mechanical wear, and speed control is attractive when an air compressor is running for long periods at part load.

Compressors benefit from dedicated features in VLT® drives. With the “skip resonance” function you easily identify for the drive which frequencies to pass to avoid frequency noise and damage.

VLT® soft starters, high-power drives, AHF harmonic filters with built-in cascade controller option, DC coils, and PID controllers are applied.
