Variable-speed drive

Finalist in HVAC/R in Consulting-Specifying Engineer's 2011 Product of the Year competition


Danfoss’ Performer variable-speed drive (VSD) integrates power electronics and scroll technology. The VSD features a high-capacity scroll compressor for R-410A refrigerant and a variable-frequency drive to deliver the capacity required for constant cooling. With a delivered capacity range for the residential market from 3 to 5 tons, the product can achieve energy savings up to 20%. The drive’s design eliminates the need for an electronic printed circuit board on the outdoor unit or a start capacitor.

The product features an internal permanent magnet (IPM) synchronous motor and exact temperature control of +/- 0.2 F.
