Diaphragm compressors for hydrogen vehicles, buses and material handling

Diaphragm compressors for hydrogen vehicles, buses and material handling

PDC Machines has developed partnerships with the largest gas producers, researchers, and technology companies to create practical and commercial worldwide acceptance of hydrogen as an energy source. PDC’s gas compression equipment can be found in commercial installations worldwide for hydrogen refueling of vehicles, buses and material handling vehicles. Today our expertise in hydrogen fueling is demonstrated globally with more than 200 compressors installed in variety of hydrogen energy applications.

Diaphragm compressors for 350 bar and 700 bar gas compression

Diaphragm compressors for 350 bar and 700 bar gas compression

PDC Machines is the leader in engineering and manufacturing practices and methods used for the production of 350 and 700 bar gas compressors. This, in part, has enabled these applications to further develop from the demonstration phase to commercialized solutions in this emerging marketplace. In addition to our 700 bar compressor options, PDC can also provide up to 1000 bar solutions for specialized applications. Flow rates from 7.5 to 350 kg/h (81 to 4,000 Nm3/h) are possible for fueling hydrogen fuel cell-powered vehicles.
