Applications for PDC Diaphragm Compressors:

High-pressure compression of fuel gases for:

• Fueling Fuel-Cell powered cars, buses and forklifts
• Fueling storage of Fuel-Cells used in backup power generation in telecommunication towers and power plants
• Residential re-fuelers for cars and power generation
• Filling and off-loading of Hydrogen from tube trailers
• Filling hydrogen cylinders and bulk storage tanks
• Life cycle testing of onboard tanks in cars, buses and forklifts
• Feedstock for chemical, petrochemical and pharmaceutical industries
• Solar to hydrogen power
• Wind to hydrogen power

Automobile Fueling

PDC specializes in providing Hydrogen compressors for refueling internal combustion engines and fuel cell powered vehicles. Models are available for applications ranging from single auto demo sites to full-scale production sites designed to fuel 25 and more vehicles per day. PDC offers engineered systems that are compatible with typical compressor inlet and discharge conditions for most Hydrogen fueling applications. Inlet pressures of 100-200 Psi (0.7-1.4 MPa) and discharge pressures of 3600, 7000, 12,000 and 15,000 Psi (25, 48, 83, 103 MPa) are available with flow rates from 50 to 2000 SCFH (1 to 54 Nm³/hr). Suction source can be from generators, reformers or tube trailers.

Bus Fueling

PDC offers a model featuring up to 3000 Psi (21 MPa) suction and 6000 Psi (41 MPa) discharge pressures with a flow rate 74,640 SCFH (2000 Nm³ /hr). This compressor can fill a typical alternate fuel bus in approximately 10 minutes.

Tube Trailers:

PDC compressors provide high-pressure compression of fuel gases for filling and off-loading of Hydrogen from tube trailers.

Gas Cylinders and Storage Vessels

PDC compressors provide high-pressure compression of Hydrogen for filling portable gas cylinders and stationary storage vessels.

Residential, Power Generation and Telecommunications

PDC offers a compact single stage model which can take 145 Psi (1 MPa) suction to 6,500 Psi (45 MPa) discharge with a flow rate of 1 Nm³ /hr, with power consumption of less than 1.5 KW. This model does not require any water for cooling. Noise level is below 85 dBA at one meter. The footprint is approximately 18” x 18” x 36” high [457 x 457 x 914mm]. The weight is 550 pounds (250 Kg.). Many customers incorporate this compressor in their portable cabinets along with their electrolyzers, reformers, cylinders, storage, fuel cells and electrical gears as a complete power producer.
