Delight at the Acrex Award of Excellence 2016 in the category ‘Green Products’: Chief Technology Officer Rainer Große-Kracht, Rob de Bruyn (Managing Director of BITZER Refrigeration Asia) and Chief Sales and Marketing Officer Gianni Parlanti accept certificates for the CSVH3 compact screw compressor)

BITZER’s new CSVH3 series received the Acrex Award of Excellence 2016. This prize is awarded by a jury of experts in various categories – including ‘Green Products’.

With the compressor’s ESEER value of over six in typical operating conditions for air cooled liquid chillers for comfort air conditioning, the CSVH3 series is setting new benchmarks in the industry. “The compact screw compressors with an integrated refrigerant-cooled frequency inverter offer maximum seasonal energy efficiency, making them sustainably environmentally friendly,” BITZER claims. The series is especially suitable for systems that frequently operate under part-load, also achieving impressively high full-load efficiency and significantly improved (E)SEER/IPLV and SCOP values.

The CSVH37 compact screw compressor has a refrigerating capacity of 550 kW (+5/50 C) and a displacement of up to 960 m3/h, while the larger CSVH38 has a refrigerating capacity of 660 kW (+5/50 C) and a displacement of up to 1,156 m3/h.

Like the smaller CSVH2 series, the CSVH3 monitors its own application limits: if a value exceeds the set parameters, a warning message is produced with the option of adjusting the performance and operating parameters. The compressor only switches off after the maximum values have been exceeded for a longer period of time. The compressors communicate with the master system controls via Modbus. The integrated data log can be used at any time to analyse operation over the running time and optimise the system settings. With the CSVH2 and the introduction of the new CSVH3 series, BITZER now offers the complete service range up to 1,156 m3/h displacement even in the field of highly efficient, speed controlled compressors with integrated frequency inverters.
