Danfoss India, a leading player in the climate and energy space, has extended its inverter scroll compressor range VZH with permanent magnetic
motor by introducing three new models. Designed for rooftops, air handling units, close control, process cooling and ground source heat pumps, VZH delivers cooling capacities between 4-7 tons and up to 13 tons in manifold confi gurations, and between 3-25 kW of heating capacity. It is designed to meet upcoming stringent energy regulations. VZH is the second generation of variable speed scroll compressors for commercial applications in air conditioning with an existing inverter scroll platform ranging from 13 to 26 TR. The expanded range is now from 4 to 26 TR (14-94 kW), and up to 52
TR in manifold confi guration. The company’s portfolio of inverter solutions includes Turbocor oil-free centrifugal compressors. VZH combines Danfoss know-how in compressor and drive design. The VZH 4-7 TR packages provide 5% higher part-load efficiency versus existing inverter technologies. Permanent Magnet Motors, optimization for diff erent pressure ratios with IDVs and 15-100% stepless modulation lead to higher energy savings and part-load effciency while drive functionalities and integrated components lower standard applied costs. Danfoss offers dedicated drives for inverter scrolls for the Light Commercial and Commercial markets. This reduces the OEM’s time to market. More information is available on cc.danfoss.com
