Heat recovery unit Waste heat recovery system

Waste heat is generated through the everyday usage of electrical machines, large boilers units or cooling systems. The rate for lost energy through flue, exhausted gas or general process heat is around 15 to 20 %. But through a waste heat recovery system can up to 90% of the exhausted heat be recovered.
