Description
DW-6.8 (1.5-2.5)-33 Hydrogen Compressor for Energy Storage Systems
The DW-6.8 (1.5-2.5)-33 Hydrogen Compressor is designed for hydrogen boosting in energy storage systems, renewable energy projects, and industrial hydrogen utilization processes.
Different from high-pressure hydrogen filling compressors, this model focuses on increasing hydrogen pressure from low-pressure sources to meet the requirements of storage, circulation, and downstream utilization systems.
The compressor is suitable for pure hydrogen compression with a flow capacity of 980 Nm³/h. It operates with an inlet pressure of 0.15~0.25 MPa.G and increases hydrogen pressure up to 3.3 MPa.G. Driven by a 132 kW motor, unit adopts a water-cooled reciprocating piston compression system for continuous industrial operation.
With its medium-capacity hydrogen handling capability, the DW-6.8 (1.5-2.5)-33 provides a practical compression solution for hydrogen energy storage facilities, hydrogen production projects, and industrial hydrogen supply systems.
