Energy recovery control unit ER 90-900

For water-cooled ZR oil-free air compressor

Contact our expert

Up to 105% total energy recovery

Turn your water cooled, oil free air ZR compressor into an energy source. Depending on site conditions, you can recover between 80% and 105% of the electrical input energy as heated water

Designed for oil-free air compressors

Our innovative design takes the heat from compression and transfers it into hot water. Connect up to 4 ZR air compressors to 1 unit

Reduce your CO2 emissions

Help save the environment by reducing energy consumption. ER 90-900 can help your company manufacture products in a more sustainable way

Plug, play and display

Visualize your energy savings strategy and create transparency in your environmental reporting

Low operating costs

The Energy Recovery unit has stainless steel plate heat exchangers, variable speed-driven pumps and a state-of-the-art control system. These ensure a long and trouble-free life

Optimal compressed air system

Single interface for your compressed air and hot water system. The ER 90-900 also regulates cooling water pressure & temperature

Compressor energy recovery - customer stories

Recover hot water for many applications

The ER control unit is to be installed between the compressor and your cooling- and heating circuits. Hot water up to 90° C can be recovered from the compressed air system. This water can be used for sanitary purposes and heating but is particularly suitable for process-heating applications. The modular design guarantees seamless integration in a wide variety of applications, even in the harshest of operating conditions.
