Introduction of the NewTon refrigeration system that uses natural refrigerant has resulted in CFC phase-out measures and an average of 15 to 18%* reduced electricity consumption

Based on the CFC Phase-out Plan, existing low-temperature refrigeration equipment in main logistics centers was updated to the NewTon refrigeration system that uses natural refrigerant. Environmental measures are promoted across the entire group, resulting in both CFC phase-out plans and energy conservation at the same time.

*At all logistics centers

Deciding Factor

Advantages

In addition to phasing out CFCs, the system’s energy-saving properties and level of perfection has been particularly praised. One deciding factor was improvement to operation and maintenance control.

• Compatible with complete phase-out of CFCs by 2020 • Power consumption has been reduced by an average of 15 to 　18% for overall logistics centers, and by approximately 30% 　for individual cooling units • A maintenance contract has enabled a more reliable operation and 　management control system with less need for manpower• Safety is maintained through indirect cooling methods and　hazard neutralizing equipment • Ammonia usage is significantly reduced

Maruha Nichiro Logistics, Inc.

As a member of the Maruha Nichiro

Group, Maruha Nichiro Logistics Inc.,

whose slogan is “Delicious delight to the

world”, is in charge of low-temperature

logistics.

With 34 logistics centers focused in

main trading ports around the country

such as Tokyo, Osaka, Nagoya, and

Fukuoka, they have built a network that

spans all of Japan. They handle a wide

variety of chilled and frozen foods such

as seafood, livestock products, and

agricultural products, providing the

absolute best in freshness and quality in

their safe, reassuring, authentic foods.

In order to comply with the total phase-

out of CFCs by 2020, they are currently

engaged in ef for ts to renovate low-

temperature refrigeration equipment

in their main logistics centers across

Japan.

Shaping Refrigeration Systems for Tomorrow

The impetus to proceed with updating low-temperature refrigeration equipment to use natural refrigerants across the entire Maruha Nichiro Group was due to the CFC Phase-out Plan.“Because production of HCFC (Freon 22) will end completely in 2020, the Maruha Nichiro Group as a whole decided to proceed with CFC phase-out as an overall policy for existing equipment and when building new cold storage facilities. In line with this plan, the refrigeration equipment in main logistics centers is being updated to use natural refrigerants one by one. We are using this as an opportunity to improve the strength of our business.” (Hiura, Director, Facilities Department)

So far, the equipment has been updated in the Toyomi (Tokyo), Funabashi (Chiba), Rokko (Kobe), Chikko (Nagoya), and Kawasaki No. 1 (Yokohama) logistics centers. “The deciding factor for NewTon was its completeness and the amazingly strong numbers for energy efficiency shown when compared to competitor products. After the Funabashi Logistics Center, we decided to implement the system in order of priority.” (Mr. Hiura)Renovation work is generally difficult. However, one of the reasons Mayekawa has been selected is for their wealth of installation experience.

A maintenance contract was concluded with the Kawasaki No. 1 Logistics Center as part of a new initiative. “In conjunction with Mayekawa, equipment s tatus can be monitored remotely. It ’s a relief to be able to see any abnormalities on a computer and check the status of other locations from headquarters. Also because you can check the status via data, there is no longer any need to use a specialist technician.”(Mr. Hiura)

One of NewTon’s features is i t s low ammonia charge of only 25 kg*, and its indirect cooling method which makes it necessary to only use ammonia in the machine room.The system has received high praise for it s consideration of safety. Its hazard removal equipment ensures double and triple safety measures that maintains safety even in the event of a leak.

“ O v e r a l l e l e c t r i c i t y consumption has been reduced monthly by 17.8% (July 2015) at the Kawasaki No. 1 Logistics Center. We’ve also achieved a reduction of approximately 20% for individual cooling units. At other centers, there are examples of energy saving on the order of roughly 15 to 18% and close to 30% for individual units.” (Mr. Hiura) Approximately 60 percent of electricity consumption at cold storage facilities is taken up by refrigeration equipment. Some centers spend as much as 50 million yen per year on refrigeration systems, with a 20% reduction resulting in nearly 10 million yen per year in savings on electrical costs. Customers are also very satisfied with operating conditions.“In six months of running the system at Kawasaki No. 1, we’ve only had one warning. With some centers having experienced one or two warnings per month, we can truly feel the good results from using NewTon.” (Mr. Hiura)In 2015, equipment in the Kitano (Kyushu) and Sakishima (Osaka) centers was updated. There are plans to switch to natural refrigerant in as many centers as possible by 2020. Future plans include pursuing phase-out of CFCs, energy saving solutions, and maintenance contracts in order to improve operations and save manpower.
