Heat Recovery

Heat recovery – saves money and saves the environment!


When using screw compressors, besides the desired primary product - the compressed air - a lot of heat is produced. RENNER developed a heat recovery system. It enables you to recover up to 85% of the applied energy as heat in the form of hot air, industrial water or heating water. It is environmentally reasonable and saves a lot of money!





Heat recovery with integrated plate heat exchanger

• For RENNER Screw Compressors 3,0 kW - 355 kW

• Standard: Temp. inlet 15°C, exit 65°C (industrial water) or temp. inlet 35°C, exit 65°C (heating)

• Further temperature ranges on demand



Install, connect, benefit!

A benefit of the external heat exchanger is the simple installation. A plumber will look after the integration into the existing water circulation. For the operation no external energy is necessary!
