Air Compressor Heat Recovery Systems

Why choose a heat recovery system? In fact, the question should be: Why not? Amazingly, virtually 100% of the electrical energy supplied to a rotary screw compressor is converted into heat energy and up to 96% of this energy can be recovered and reused for heating purposes using air compressor heat recovery systems.

This not only reduces primary energy consumption, but also significantly improves a company’s overall energy balance. The fully-enclosed design of modern rotary screw compressors makes them particlarly suitable for air compressor heat recovery and this applies to both oil lubricated (fluid-injected) and oil-free compressors.

Energy costs can account for up to 80% of life-cycle costs over the lifetime of a compressor. By utilising heat recovery systems, these costs can be significantly reduced whist also effectively lowering the CO2 emissions of an organisation because energy is utilised more efficiently.

By reusing the exhaust heat from the compressor, booster or blower package, heat exchanger systems can recover up to 76% of the heat energy to provide heated water that can then be used in production, in your heating system or as service water on demand at temperatures up to +70°C, or even +90°C if required.

For standard applications using heat recovery systems for the production of hot water and service water, PTG platetype heat exchangers are used. This significantly reduces the amount of primary energy required for heating purposes. Special, fail-safe heat exchangers are used in the case of operations without an interconnected water circuit, or for applications with the highest demands of purity for the heated water, such as with cleaning water in the food industry.
