Using variable frequency drives (VFDs) to control the speed of a compressor can provide improved occupant comfort and quieter operation in air conditioning and heat pump applications. Always consult with the specific compressor manufacturer before using a VFD controller on any compressor.
Industrial refrigeration customers can benefit dramatically from the expertise and advice of a knowledgeable refrigeration contractor. These larger refrigeration systems present tremendous opportunities for energy efficiency improvements that can lead to significant operational savings.
While variable-frequency drives (VFDs) boast increased energy efficiency as the main benefit, a small — but by no means insignificant — percentage of the drives are causing major problems in the motor they control.
The P-Series line of variable frequency drives (VFDs) has been enhanced with a new redundant VFD unit. The Redundant Drive Panel (RDP) is designed to provide an economical HVAC motor control solution that maintains full control of an application if the primary drive fails.
