Core Technology

Hydraulically Driven Hydrogen Compressor

Driven by a hydraulic pump, hydrogen is compressed to the required pressure and delivered to the application. As the hydraulic pump rotates, it draws hydraulic oil into the pump, where the oil is pressurized. This pressure increase compresses the hydrogen to the desired level.
