Hydrogen systems often require compressors that can handle unstable supply conditions while maintaining stable outlet pressure and gas quality.
In industrial hydrogen applications, the compressor needs to adapt to different hydrogen sources, control temperature during compression, and minimize contamination risks.
The DW6.74(3.3)/0.7(5-12)-12 Hydrogen Compressor is developed for these requirements, providing stable hydrogen compression for industrial processes.
The compressor supports hydrogen flow conditions from 600Nm³/h to 2500Nm³/h, with a discharge pressure of 1.2MPa.G.
Why This Hydrogen Compressor Fits Industrial Applications
The DW6.74(3.3)/0.7(5-12)-12 is designed for hydrogen systems with different inlet pressure conditions. The compressor can be applied according to different process requirements.
The compressor adopts an oil-free lubrication design, helping avoid lubricating oil entering the hydrogen compression chamber and supporting cleaner hydrogen handling.
The three-stage compression arrangement is designed for hydrogen compression processes requiring multi-stage pressure increase.
The D-type balanced structure helps maintain stable mechanical operation during reciprocating compression.
Hydrogen System Applications
The DW6.74(3.3)/0.7(5-12)-12 can be applied in hydrogen-related industrial systems, including:
Used in industrial hydrogen process systems requiring compressed hydrogen supply.
