ZR 90-160 VSD +

Meet the latest oil-free rotary screw air compressor that delivers up to 35% energy savings.

Find our more about the energy efficient ZT 90-160 air-cooled oil-free screw compressor.

Volkswagen and Veolia in industrial heat recovery project for local community Veolia Energy Poznań with Volkswagen Poznań have launched a joint project for industrial heat recovery. Energy, heat from industrial processes, is used to supply more than 30 buildings in the district Wilda, including the HCP hospital in Poznań. Thanks to our oil free screw compressors, which are necessary in the foundry of Volkswagen Poznań, this very energy-intensive process (up to 80% of the electricity consumed by the compressor goes into heat energy) is transformed to power the municipal heating system.
