Heat Recovery Systems

Definition

Heat recovery systems are technologies designed to capture and reuse waste heat that would otherwise be lost during industrial processes, heating, or cooling. These systems improve energy efficiency by transferring recovered heat to areas where it can be utilized, thus reducing overall energy consumption and operational costs.
