Ecology first for Central Japan Railway Company



Since its establishment in 1987, the Central Japan Railway Company (JR Central) has vigorously promoted technological development. July 2002 saw the opening of their newest research center in Komaki in southern Japan.

With a responsible focus on the environment, the new facility incorporates ecological technology in a number of applications, including solar power, cogeneration and ice storage.

The Situation
The 20 hectare complex in Komaki contains over 12,500 square metres of offi ce space, large-scale test equipment, an outdoor test track, a wind tunnel, a Shinkansen Bullet Train driving simulator as well as global environment conservation facilities.

The global environment conservation facilities were to include a 560kW energy-saving cogeneration system. JR Central wished not only to make a contribution to conserving the global environment, but also to be able to pursue technical development in the fi eld of new energy sources.

The Grundfos Solution
Over 50 multistage CR pumps have been installed, playing an important part in the center’s cogeneration system. In cogeneration, heat energy and electrical or mechanical power is produced from the same fuel in the same facility. Here, waste heat (as in steam) can be used to produce electricity or employed as a heating source.

The Outcome
JR Central presently enjoys low energy consumption, a large amount of free fl oor space and elegant installation where Grundfos is incorporated into their systems.

Grundfos pumps provide high-quality, reliable operation within hot water circulation, as just one example. The vertical pump category furthermore suits the Japanese market well, where land is sparse.

Efficient operation - Energy savings - Integrated system solution




The Central Japan Railway Company (JR Central)


  • Effi cient operation
  • Energy savings
  • Integrated system solution



  • 51 CR/CRN pumps


CR pumps
Rows of CR pumps shine in Japan performance wise, ecologically and visually.


The Shinkansen Bullet Train
The Shinkansen Bullet Train makes the 550 km trip between Tokyo and Osaka in approximately 2.5 hours.

Site designer Takeshi Ushikoshi says: “First of all, the Grundfos CRN multistage pump has an outstanding effi ciency and superior running cost parameters. The high effi ciency suits our energy saving demands. Moreover, designing the pump installations was facilitated by their in-line design, where we also saved valuable fl oor space.”
