Energy Recovery Systems from The CMM Group can be incorporated into new air pollution control systems (APCS) (or other high temperature emitting devices) or be retrofit or added to an existing process. Energy recovery systems utilize the 100°C (212°F) to 815°C (1,500°F) of heat energy (depending on the heat emitting technology in use) that would normally be exhausted directly into the atmosphere.
