THE RELIABLE SOLUTION FOR CLEAN HIGH-PRESSURE AND EXTREME-PRESSURE COMPRESSION sera has provided reliable gas compression solutions without oil, contamination or leakage for many decades. Our newly developed, innovative dry-running piston compressors with electrohydrostatic drives perfectly complement our established metal diaphragm technology. They enable reliable and energy-efficient compression of particle-free gases such as hydrogen, nitrogen, helium, argon or ethylene to extreme pressures without the use of lubricants. These innovative piston compressors from sera are ideal when large...

HYDRAULICALLY COUPLED COMPRESSOR STAGES ELECTROHYDROSTATIC DRIVE The compressor unit consists of two coaxially arranged vertical gas cylinders, each mechanically connected to and driven by a hydraulic cylinder. A space between the gas cylinders and drive cylinders safely prevents hydraulic fluid from contaminating the medium. The two drive cylinders are hydraulically coupled with each other via a connecting line. The gas cylinders are liquid cooled using an outer cooling jacket. This dissipates frictional heat and significantly extends the service life of the seal and guide systems. The...

MARKETS AND APPLICATIONS Hydrogen refuelling stations At a time when fossil fuels are running out and environmental protection is becoming increasingly essential to our planet, hydrogen refuelling stations have found their place in the energy revolution. Vehicles powered by fuel cells require gaseous hydrogen for refuelling. Our innovative compressor is ideal in this application, compressing large quantities of H2 to up to 1,000 bar. The unique design reliably prevents fuel contamination and satisfies the high cleanliness standards required by vehicle manufacturers. Power-to-gas...

MARKETS AND APPLICATIONS Hot isostatic presses The extreme-strength metal and ceramic components with low dimensional tolerances which are found in the aerospace and automotive industries are often produced using hot isostatic presses. Here, parts are simultaneously hot-pressed and sintered at temperatures of up to 2,000 °C and pressures of 1,000 to 2,000 bar using inert gas. This manufacturing technology generally uses argon, which can be compressed reliably and energy efficiently with our electrohydrostatically powered dry-running piston compressors. Airbag inflators Airbags have...
