Factory waste heat utilization

In many cases, heat such as exhaust gas and exhaust steam emitted from factories is thrown away without being used. By converting this heat into chilled water with a waste heat utilization machine and using it for the base operation of existing air conditioners and chilled water generators, it is possible to significantly reduce the energy consumption and CO₂ emissions of existing machines.

Factory waste heat utilization

Gas equipment manufacturer　（Use of waste heat from aluminum diecast furnace）

  • Business type
    Gas equipment manufacturer
    Model
    Water fired chiller 10RT
    Available heat
    51kW(waste hot water)
    Chilled water application
