Advanced efficiency, extended

Danfoss inverter scroll compressor VZH is the second generation of scroll compressors offering variable speed technology for commercial applications in air conditioning. It allows OEMs to stand out in the commercial HVAC and process cooling marketplaces from 4 to 52 TR (15 – 184 kW) and to exceed the upgraded energy level requirements.

Boost your packaged air conditioning units, rooftops, chillers with the Danfoss VZH range.

The energy regulations generate several challenges that can be easily taken up with variable speed technology. Inverter compressors are the best way to obtain and exceed the energy standards with high part-load and seasonal efficiency while providing several other key benefits.

On top of the advantages provided by the technology (precise cooling and humidity management, low start-up current, energy efficiency etc.), Danfoss inverter scrolls VZH have specific features that offer high value to the customers and end users.

The second generation of inverter solutions by Danfoss is now stepping beyond the energy point of view. The optimization for different pressure ratios and permanent magnet motors in inverter scroll compressors are the major contributors to these performance levels.
