Japanese OEM Nihon Netsugen Systems has sold a total of 250 CO2 transcritical systems in Japan to date and is aiming for 350 by next year, said Katsuhiko Harada, president of Nihon Netsugen Systems during the FOOMA Japan 2021 exhibition, which is being held in Nagoya, Japan from June 1-4.
FOOMA Japan (short for the International Food Machinery & Technology Exhibition) is one of Asia’s largest exhibitions for food machinery and food processing technologies. The event was last held in 2019, skipping 2020 due to the COVID-19 pandemic.
The company is exhibiting its recently developed “F-3” transcritical CO2 (R744) Booster Super Green system — a new addition to its line-up of low-temperature transcritical CO2 condensing units aimed at the cold storage and food processing industries. The “F-3” model has a cooling capacity of 102kW (29TR). Its existing “F-1” model has a cooling capacity of 34kW (9.6TR) and its “F-2” model has a cooling capacity of 68kW (19TR).

Harada added that an additional “F-4” model, with a cooling capacity of 160kW (45.5TR), will be available for sale in Japan this summer.
NNS’s CO2 systems are seeing adoption in Japan in a wide range of applications from cold storage to beer brewing, margarine production and ice making. Harada said that the company also expects to have its CO2 systems serve ice cream makers in the near future.
In February 2019, Harada announced during ATMOsphere Japan, that the company had sold 120 of its CO2 systems in Japan since production first began in December 2017.
