ATMOsphere Asia 2014, organised 3-5 February, in Tokyo, Japan, provided a showcase for some of the most advanced CO₂ commercial refrigeration technologies to be developed by Japanese companies. The increasing number of CO₂ solutions offered in the Japanese commercial refrigeration market, a trend already evident at HVAC&R Japan 2014, demonstrates the increasing innovation and competition in this market, with solutions being offered by Panasonic, SANDEN and Nihon Netsugen.
