Group Legerlite has replaced its production unit; the molding machine and the pre-expandor and wanted to reduce its energy bill. The molding process was releasing a significant amount of heat so C-nergie decided to install a heat recovery system on the water basin of the molding machine.
The recovered energy is now used to pre- heat pre-expender air, make up water for steam boilers and primarily heat the air in a new 30,000 CFM ventilation unit.
The benefits are:
-48 893$ of savings on the heating costs;
-162 600 m³ of natural gas saved;
-Return on investment period of 3.9 years;
-425 000$ in subsidies;
-307 tons of GHGs/year; The average annual consumption of 77 passenger vehicles;
