Diaphragm Compressors for leak-tight and contamination-free compression of all types of gases including Argon, Fluorine, Silane, Nitrogen, Nitrogen Trifluoride, Oxygen, Hydrogen, Helium, Ethylene, Sour gas, TFE, Xenon, Neon and many other gases

• Flammable, oxidizing, toxic, and radioactive gases
• Supercritical fluids and solvent extraction systems
• Research and Development
• Filling and off-loading gases from tube trailers

For details:

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 from high pressures 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 major gas producers, distributors and supply houses.




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 any type of gas such as monosilane, nitrogen trifluoride, silicon tetrafluoride, oxygen, fluorine, hydrogen, argon, helium, neon, deuterium, nitrogen, ethylene, carbon dioxide, carbon monoxide, methane, 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.
