Compressors: Danfoss

Danfoss-021714-body.jpgDanfoss will extend its inverter scroll compressor range VZH to include three new models. According to the company, the variable speed VZH compressors provide efficiency at part-load conditions, and can improve efficiency by more than 30% compared to fixed-speed compressors.

Designed for small rooftop and process cooling applications, the new inverter scroll compressor range VZH will introduce cooling capacities between 4 and 6.5TR with a single compressor, and up to 13 tons with a manifold configuration. With a permanent magnet motor and patented Danfoss Intermediate Discharge Valves (IDV), which can help improve part-load efficiency by up to 24%, the new variable speed compressor range VZH will facilitate efficiency ratings up to 21 IEER and can modulate from 15 to 100 RPS.

Additionally, a pre-qualified package, including the Danfoss inverter scroll compressor VZH and drive optimized to work together, is fully integrated to save time in unit development, ensure a more reliable solution to improve product time to market, and enhance overall system efficiency.
