3-1. Actual Installation in Japan (Dec. 2013)
Hokkaido: 7
Tohoku: 20
Kanto: 54
Chubu: 17
Kansai: 17 Kyusyu: 15 (incl. Okinawa: 1)
■ As of today, 450 CO2 units were installed in 145 locations,
From subarctic Hokkaido (北海道) to subtropics Okinawa (沖縄),
From CVS to Hypermarket including Distribution Center.

Data 4. Issues and Future action
4-1. Issues of CO2 units and our Future Action
1. Acquisition Cost Reduction
System Design simplification, Piping materials (tube and fittings)
standardization and availability / access improvement.
The reduction of cycles per store will also reduce the total cost.
(High Pressure Gas Safety Law need to be amended for CO2.)
2. Product Improvement
Efficiency, Noise, and Vibration can be further improved.
Product Line-up need to be improved. Indoor units to be diversified and Outdoor units to be standardized.
3. Training of Installers
Trainings for CO2 are indispensable. (Installation, Operation check, and Service Maintenance) Original Manual was prepared and Training courses were held.
FY2010 FY2011 FY2012 FY2013
# of Trainee 46 200 211 (250)
More than 650 people already took CO2 training course as of Dec. 2013
Contribute to the prevention of
Global Warming by utilizing CO2
4-2. Issues of CO2 units and our Future Action
In order to expand the use of CO2 refrigerant for Commercial
Refrigeration Sector in Japan, Cooperative actions in different levels
of industry Stake holders are required.
