Heat Recovery Saves Money and Benefits the Environment

Heat Recovery Saves Money and Benefits the Environment

Why recover heat?
The question should in fact be: Why not recover heat? Amazingly, almost 100 percent of the electrical energy input to a compressor is converted into heat. 96 % of this energy can be recovered and reused for heating purposes.

Heat recovery Minimise primary energy consumption for heating
The enclosed, compact design of modern rotary screw compressors makes them especially suitable for heat recovery. Direct use of the recyclable heat via a ducting system enables up to 96 % of the compressor’s total energy requirement to be recovered and used for heating purposes. This is the case irrespective of whether fluid-injection cooled compressors or dry-running screw compressors are used.

Minimise primary energy consumption for warming process, heating and service water
PTG and SWT heat exchanger systems can provide on-demand heating and service water heated to temperatures up to 70°C, or even 90°C, depending on requirement. Conventional warming of heating and service water using recyclable heat is performed by PTG plate heat exchanger systems, whilst SWT fail-safe heat exchangers are recommended for applications that have no other interconnecting water circuits and where it is essential that the water being warmed remains uncontaminated.
