The VZH inverter scroll compressor is optimized for different pressure ratios to increase energy efficiency. Courtesy: DanfossThe VZH inverter scroll compressor uses a brushless interior permanent magnet (IPM) design and is optimized for different pressure ratios to deliver energy savings of more than 30 percent compared to a fixed or mechanically modulating compressor. The variable speed technology provides infinite and smooth capacity modulation, delivering precise temperature control within ±0.3°C/0.1°F of the set point. A 4:1 modulation ratio allows the VZH inverter scroll compressor to modulate from 25 to 100 RPS for greater savings. Furthermore, pre-equipped tandem capability extends the cooling capacity to 52TR and a 12 to 100 percent stepless modulation where low part-loads are needed.
