Bitzer won the ACREX 2016 Award of Excellence in the Green Products category for its new CSVH3 series compressor. This prize is awarded by a jury of experts in various categories including Green Products. The compressor has a seasonal energy efficiency (ESEER) value of over six in typical operating conditions for air-cooled liquid chillers for comfort air conditioning. The compact screw compressor has an integrated refrigerant-cooled frequency inverter and high ESEER, making it sustainably environment friendly. The series is suitable for systems that frequently operate under part load, also achieving high full-load efficiency and 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 switches off only 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 in the field of high efficiency, speed controlled compressors with integrated frequency inverters.
