PDC Machines is a world leading manufacturer of diaphragm compression solutions. Our compressors are industry renowned for their reliability and robust performance, and the preferred choice for ultra-high purity gas applications requiring contamination-free and leak-tight compression. PDC’s equipment is ideally suited to compress and maintain purity of high-purity gases. It is also appropriate for compressing volatile, rare, inert, explosive, pyrophoric, toxic, synthetic, and corrosive gases. PDC serves industrial gas and hydrogen energy markets, and our compressors are found in virtually every industry worldwide. We supply everything from bare compressor units to fully automated compression systems with PLC controls, and we provide lifetime service for our equipment. PDC’s aftermarket capabilities extend to offer support and parts for PDC equipment, as well as Non-PDC compressors.
PDC Machines is headquartered in the United States, with systems installed globally and supported by an international service and partner network. PDC’s headquarters is located in Souderton, Pennsylvania, approximately 1 hour north of Philadelphia and 2 hours Southwest of New York City.
PDC Machines was founded in 1977. We have decades of experience in the diaphragm compression space and today serve a global customer base, with over 2100 compressors installed since 2010.
The best way to select a compressor is to work directly with the PDC Machines team. Our engineers evaluate gas type, pressure, flow, duty cycle, and site requirements to recommend the optimal solution.
Yes. PDC Machines compressors provide completely oil-free gas compression, the gas is completely sealed off from lubricants and mechanical components, resulting in oil-free, leak-tight compression.
Yes. PDC Machines regularly supplies compressors that are integrated into existing plants, skids, and process systems across a wide range of industries. We also work with regional partners who package our bare compressors into complete systems.
Yes. PDC Machines specializes in engineered-to-order compressor systems tailored to specific gases, pressures, flow rates, and site requirements. We can provide anything from a bare compressor block to skidded and containerized, fully instrumented systems with controls.
PDC Machines offers comprehensive service and support, including installation assistance, spare parts, maintenance, and long-term service programs. PDC’s service teams are the best in the industry. Our global network of engineers and technicians are available to provide remote technical support as well as a full range of on-site services. We support every aspect of compressor operation, including startup and commissioning, routine operation, maintenance, and troubleshooting. In addition to servicing PDC equipment, our experienced team is also equipped to support and maintain any diaphragm compression system, helping customers optimize performance across a range of platforms.
Yes. PDC Machines provides service and technical support for non-PDC compressors, leveraging decades of compression expertise to support a wide range of equipment in the field.
Yes. In addition to servicing non-PDC equipment, PDC Machines can supply replacement and aftermarket parts for non-PDC compressors, helping customers extend equipment life, maintain performance, and minimize downtime.
PDC Machines compressors are used to compress a wide range of gases, including (but not limited to) argon, carbon dioxide, carbon monoxide, deuterium, ethylene, fluorine, germane, helium, hexafluoropane, hydrogen, krypton, methane, neon, nitrogen, oxygen, polypropylene, silane, sour, syngas, tetrafluoromethane, xenon and gas mixtures.
Yes. In fact, PDC Machines’ legacy is rooted in industrial gas compression. Long before hydrogen applications expanded, PDC compressors were widely used for a broad range of industrial, specialty, and process gases. These include helium, nitrogen, fluorine, argon, methane, xenon and oxygen, just to name a few. This deep experience across gas types allows PDC to design compressor solutions tailored to the specific properties, purity requirements, and operating conditions of virtually any gas application.
PDC Machines compressors are used across a wide range of gas compression applications, including tube trailer loading and unloading, high-pressure cylinder filling, and storage vessel loading. They also support direct supply to process applications where gas is fed continuously into production systems, as well as gas circulation and recycle duties that require reliable, repeatable performance. This versatility allows PDC compressors to be integrated into both distribution infrastructure and critical process operations across multiple industries.
PDC Machines compressors are used across a wide range of industries where reliable, high-pressure gas compression is critical, and maintaining gas purity is essential. Our systems support industrial gas markets, including chemical and petrochemical processing, specialty and welding gases, aerospace and defense, electronics and semiconductor manufacturing, as well as energy and hydrogen applications, including hydrogen refueling, renewable energy storage, and industrial hydrogen supply. This broad adoption reflects diaphragm compressor’s flexibility to handle multiple gas types, pressures, and duty cycles, making them a trusted solution for both established industries and emerging clean-energy applications.
PDC Machines specializes in high-purity gas compression, which includes hydrogen. Our compressors are designed to handle virtually any gas, and our legacy is built on decades of experience compressing a wide range of industrial, specialty, and process gases. While hydrogen has become a major focus due to its unique challenges and growing demand, that experience is backed by a broad foundation across many gas types, pressures, and applications, allowing us to deliver reliable solutions well beyond hydrogen alone.
Yes. PDC Machines is a global leader in hydrogen refueling compression, with more hydrogen compressors installed in HRS applications than any other supplier worldwide. With over 1,000 hydrogen compressors deployed around the globe, PDC systems support both gaseous hydrogen storage and vehicle fueling infrastructure, delivering proven reliability, high availability, and performance in real-world station operation. We can also support liquid hydrogen (LH2) with our Boil-Off-Gass solutions, helping minimize losses and improve overall system efficiency.
