Japan-based system manufacturer Nihon Netsugen Systems (NNS) is exhibiting its CO2 Booster Super Green system for the first time at the FOOMA Japan 2018 exhibition being held in Tokyo, Japan from 12-15 June.

The transcritical CO2 system, which NNS launched in Japan last year , is part of a growing trend of transcritical CO2 systems being used in the food manufacturing and cold storage industry in Japan.

Ice cream, frozen food makers, breweries using CO2

NNS initially targeted the cold storage and logistics facility sectors for its CO2 Booster Super Green system. However, the manufacturer is now beginning to see interest from a wider range of customers, NNS President Katsuhiko Harada told this website.

“Our main customers [are] cold storage, logistics centres, and freezer businesses such as food industry [manufacturers of] ice cream or frozen food,” said Harada.

“For the next projects, now we are working on [a] brine chiller unit for [a] brewing company, and margarine production. Therefore we can announce [this] kind of new application [in the] very near future.”

“For the future solution, of course, we understand [that] freon gas is no longer sustainable.

Future growth

Harada said NNS is confident in the use of natural refrigerant-based systems as a future sustainable technology for industry in Japan.

“For the future solution, of course, we understand [that] freon gas is no longer sustainable. Therefore, we [think that] CO2 or ammonia will be the next solution.”

Particularly for the Japanese market, in commercial and industrial applications, Harada believes CO2-based solutions have a number of advantages over ammonia.

“People in Japan especially, are really afraid of ammonia so for commercial refrigeration or more public refrigeration, we chose CO2 [because it] is more safe and easy to handle. That is the reason we chose to develop [with] CO2.”

NNS is currently manufacturing the systems at its factory in Shiga, Japan and is aiming to produce more than 100 units per year.
