German company Sera provides tailored solutions for precise gas compression in various applications. The new dry-running piston compressors complement metal diaphragm technology, offering a reliable and energy-efficient alternative for gas compression. Thanks to the innovative design and special configuration of the sealing and control systems, conventional lubrication is not required, even under extreme pressure conditions. The sealing and control systems are easily accessible and can be replaced without completely disassembling the equipment. Long stroke length and low piston speeds enable quiet operation and minimal wear.
Technical performance of dry-running piston compressors:
- Inlet pressure: 25–30 bar(g)
- Discharge pressure: max. 300 bar(g)
- Gas temperature: -10°C to +40°C
Typical applications for this type of compressor include “home-power” systems.
Typical applications of metal diaphragm compressors:
- Gas cylinder filling systems
- Production of gas mixtures
- Gas shielding in surface treatment processes
- Hydrogen refueling stations
- Power-to-gas systems
- Use in research facilities
- Nitrogen compressors for butyl production
The near-complete leak-tightness of Sera’s metal diaphragm compressors enables the safe compression of gases critical to human and environmental safety. For this reason, Sera metal diaphragm compressors are often used in applications involving toxic gases. The high-quality materials used ensure excellent corrosion resistance and a long service life.
