Linde Hydrogen fuel cell station for fork-lift refueling, using a PDC hydrogen diaphragm compressor
PDC supplied hydrogen diaphragm compressor as part of an Air liquide re-fueling station for material handling equipment in Alberta, Canada.
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.

PDC compressors provide high-pressure compression of fuel gases for filling and off-loading of Hydrogen from tube trailers.
PDC compressors provide high-pressure compression of Hydrogen for filling portable gas cylinders and stationary storage vessels.
Compressors for cylinder filling and transfilling applications:
If you are not currently using a diaphragm compressor, chances are you are sending tube trailers back with non-refundable levels of unused gas. Or perhaps you are filling cylinders partially while waiting for the next trailer. In either case, you are losing time, money, or both.
But if you were using a PDC diaphragm compressor, you'd be able to draw your gas sources down to a minimum return level and enjoy two benefits. You'd avoid being charged for any unused gas, and at the same time you'd be completely filling your cylinders and lowering your fill cycle time. Also, having a PDC diaphragm compressor at your site gives you the ability to top up your ground storage during off peak times and allows you to cascade fill your cylinders during peak fill times. This lowers your fill cycle time and saves you time and money.

If you are moving gases from tube trailers or gas generators, or compressing flash off from liquid storage, PDC diaphragm compressors are the ideal choice. Built to last and designed for reliability, our transfilling and cylinder filling diaphragm compressors are in use worldwide supporting the transfilling and cylinder filling operations of all of the major gas producers, distributors and supply houses. From 99.999% helium to welding gas mixes, PDC's diaphragm compressors are the best choice for high purity cylinder filling. The triple diaphragm design guarantees that the process gas will not be contaminated nor will it be vented to the atmosphere due to blow-by entering the crankcase. This means that high purity gas will remain high purity. If you're transfilling hazardous, reactive, toxic, or pyrophoric gases such as monosilane (SiH4), nitrogen trifluoride (NF3), silicon tetrafluoride (SiF4), oxygen (O2), fluorine (F2), or any other industrial or specialty gas, a PDC diaphragm compressor will allow you to do it safely, cleanly and reliably. Whether you are transfilling from tube trailers, cylinder filling for resale, or bottle filling for lab use, a PDC diaphragm compressor is the right tool for the job.

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.
PDC compressors provide high-pressure compression of fuel gases for gas blending, re-cycling, mixing and pressure boosting of gases for wind power, solar power and bio fuels.

The electrical power from wind turbines can be used to supply a water electrolyser, in order to electrochemically
split water into its elements, hydrogen and oxygen. Electrolysers can operate with variable power input.
The hydrogen produced can be compressed and stored for later use, either in a stationary fuel cell to produce
electricity when there is no wind, or to supply a hydrogen vehicle.
