Bock at the Gustav Lorentzen Conference 2010

Natural refrigerants – real alternatives. This is the motto of this year's Gustav Lorentzen Conference in Sydney, Australia. The International Institute of Refrigeration (IIR) and the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) invite the worlds leading experts to the most important event in the field of natural refrigerants.

For the first time since its establishment in 1994, the Gustav Lorentzen Conference will be held in the southern hemisphere, following previous successful events in different European countries as well as in the US. The conference brings together the world's leading professionals of this industry to discuss the latest findings in research and development in the field of natural refrigerants.

For the field of refrigerating compressors, Mr. Manuel Fröschle, product manager for CO2 applications at Bock, will present latest developments in compressors and refrigeration systems using the refrigerant R744 (CO2).

Bock is involved in the development of the refrigerant CO2 (R744) since the early 1990's. The fact that CO2 does not have the potential for ozone depletion and therefore has little influence on the greenhouse-effect, made CO2 an attractive alternative to conventional refrigerants in the last years. Especially when building refrigerating plants for supermarkets, plant operators often decide in favour of the application of CO2. Bock has different series for the application of the refrigerant CO2, both for transcritical use up to a pressure of 130 bar and subcritical cascade systems for pressures up to 40 bar.
