Green-Y Energy AG

Discover Green-Y Energy AG

Green-Y’s patented oil-free, water-lubricated screw compressors are up to 20% more efficient than conventional systems. They are used as stand-alone products in industries requiring clean compressed air and as the core component of a unique compressed air energy storage (CAES) system. The CAES delivers electricity, heat, and cold with one device - emission-free, modular, and free of critical raw materials, enabling full sector coupling in industrial and commercial settings. Developed and manufactured in Switzerland.

In our collaboration with Welotec, their reliable and industrial-grade communication technology has enabled stable remote monitoring and secure data exchange within our compressor systems. This accelerates commissioning processes and simplifies integration into customer infrastructures.
