Nuremberg, Germany: Following extensive testing and an intensive qualification programme, compressor specialist, Bitzer, has said in an announcement that it has approved several compressor series for HFO/HFO blends. The company showcased several models that are now also designed for refrigerants with low global warming potential (GWP) at the Chillventa 2016, which was held from October 11 to 13, at the Nuremberg Exhibition Centre (hall 7, stand 330), said the announcement.
According to the announcement, the company is developing its compressors and condensing units for use with natural refrigerants, such as CO2, ammonia, hydrocarbons and HFO/HFO blends, and also adapting its service to meet current requirements. Furthermore, it said that the company has promoted the qualification and documentation of its semi-hermetic and hermetic compressors, its condensing units and its water-cooled condensers with HFO/HFO blends.
The company said that its reciprocating compressors, semi-hermetic and compact screw compressors, and scroll compressors for series application are currently HFO ready.
“HFO ready is more than just a term for Bitzer,” said Rainer Große-Kracht, Chief Technology Officer of Bitzer. “It means that the compressor, the condensing unit or the condenser has undergone full qualification, which at Bitzer tends to be extremely demanding. For instance, it can include intensive measurement of the performance data and extensive risk analysis, if the refrigerant in question belongs to the A2L or A3 category.’
Große-Kracht added: “We therefore provide system suppliers with the opportunity to respond to end users’ demands and desires for sustainable, environmentally friendly refrigerants. In this way, system operators receive a solution tailored to their specific needs as well as high energy efficiency, reliability, serviceability and sustainability.”
