BITZER has approved several compressor series for HFO/HFO blends. The company showcased a number of models that are now also designed for refrigerants with low global warming potential at the Chillventa 2016 trade fair at Nuremberg from 11 to 13 October. This is in line with BITZER’s strategy to develop compressors and condensing
units for use with natural refrigerants such as CO2, ammonia, hydrocarbons and HFO/HFO blends, and adapting its service to meet current requirements. BITZER has also promoted the qualification and documentation of its semi-hermetic and hermetic compressors, its condensing units and its water-cooled condensers with HFO/HFO blends. BITZER’s reciprocating compressors, semi-hermetic and compact screw compressors, and scroll compressors for series application are now HFO ready. BITZER presented the new CSVH2 compact screw compressor series approved for HFO/HFO blends to the general public for the first time at Chillventa 2016. The CSH and CSW series have been approved for R1234yf, R1234ze(E), R513A and R450A refrigerants since the beginning of 2016. The company has also developed the ECOSTAR LHV5E and LHV7E condensing units with integrated ECOLINE VARISPEED reciprocating compressors, optimised the LHV5E and LHV7E models in accordance with the F-gas Regulation and the EU’s Ecodesign Directive, and approved them for HFO/HFO blends. The Association of European Refrigeration Component Manufacturers (ASERCOM) certified 32 BITZER
compressors and condensing units in 2015. These include the ECOLINE reciprocating compressors, which are designed for use with the eco-friendly R448A and R449A refrigerants. The company has integrated both of them into the BITZER software.
