Chateraise, a Japanese French pastry chain, will install the first transcritical CO2 (R744) system made by SCM Frigo in Japan, according to a recently published video by Japanese manufacturer Miyazawa, SCM Frigo’s sales representative in Japan.
Miyazawa is a manufacturer of food processing equipment based in Nagano, Japan. In January 2020, the company signed an exclusive sales agreement with SCM Frigo, the Italian CO2 refrigeration system manufacturer (and subsidiary of Swedish manufacturer Beijer Ref).

In the video, a Miyazawa representative addresses a number of topics about the CO2 system, including the benefits of using CO2 as a refrigerant, the system’s specific components and features, installation costs and maintenance support.
“The most important feature of this system is that the refrigerant is CO2, a non-freon refrigerant,” said the Miyazawa representative.
“The biggest benefit of using CO2,” the representative continued, “is that it has a low global warming potential. Compared to current freon-based refrigerants, the amount of CO2 reduced is 2,000 to 4,000 times lower. In addition is the running cost. Compared to freon-based systems, running costs can be reduced by 10 to 15%.”
Components for the system shown in the video were supplied by Bitzer, Temprite, Refrigera, Danfoss, LU-VE and Guntner.
In September of last year, SCM Frigo posted images of its CO2 systems being shipped to Japan. “Other 2 Transcritical Chiller[s] in PNC Frame ready to be shipped in Japan!” the post said. PNC refers to the Plug n’ Cool version of its outdoor compressor pack, according to SCM Frigo’s website.
