In Partnership with Nature


Sanden's Akagi plant is designated as an award-winning model for the coexistence of manufacturing and the environment

Named "Sanden Forest," our manufacturing facility lies at the base of Mount Akagi, in central Japan, surrounded by woodland with abundant oaks and evergreens, ponds and wildlife. Sanden produces state-of-the-art CO2 heat pump water heaters, vending machines and refrigerated open cases at this facility. The plant, designed to work in harmony with nature, includes:

  • Computer-controlled heating, cooling and lighting technologies that conserve energy and use renewable resources
  • Intensive recycling and waste reduction processes that allow us to produce zero waste (even food waste is composted and used to fertilize surrounding vegetation)
  • Continual monitoring and improvements in the manufacturing process to minimize energy consumption, material usage and waste
  • Environmental initiatives to promote air and water quality in the local area
  • Wildlife habitat improvement projects, environmental education events, and scenic public nature trails
