DW-9.55/0.03-16 Low Pressure Hydrogen Compressor for Fuel Cell Stations
The DW-9.55/0.03-16 Low Pressure Hydrogen Compressor is developed for hydrogen supply systems where hydrogen needs to be boosted from low-pressure sources to meet the pressure requirements of fuel cell stations and industrial applications.
Unlike conventional hydrogen compressors used for high-pressure filling, this model focuses on hydrogen pressure increase from the upstream supply side. It helps maintain a continuous hydrogen flow between hydrogen producion equipment, storage systems, and fuel cell utilization units.
The compressor is designed for pure hydrogen compression with a capacity of 515 Nm³/h. It operates with an inlet pressure of 0.003 MPa.G, inlet temperature up to 40℃, and discharge pressure of 1.6 MPa.G. Driven by a 90kW motor, the unit adopts a water-cooled reciprocating piston structure for stable hydrogen boosting operation.
The DW-9.55/0.03-16 provides a dedicated solution for fuel cell hydrogen supply, hydrogen energy projects, and industrial hydrogen circulation systems.
Fuel cell stations require a stable hydrogen source with suitable pressure and flow conditions.
The DW-9.55/0.03-16 is mainly used as a hydrogen boosting unit between the hydrogen source and fuel cell equipment. It improves the usability of low-pressure hydrogen and supports continuous hydrogen delivery.
Typical system applications include:
• Hydrogen supply for fuel cell stations
• Hydrogen production and utilization connections
• Hydrogen circulation systems
• Hydrogen storage pressure boosting
• Clean energy demonstration projects
