About SITEC-Sieber Engineering AG

SITEC-Sieber Engineering AG, headquartered in Maur (ZH), develops and manufactures systems and individual components for high-pressure technology. The portfolio includes high-pressure valves, fittings, tubing and hoses, pressure vessels, pressure generators, tools and accessories as well as electrical feed-throughs up to 7000 bar. In addition, the company offers modular HP pilot plants, including for supercritical CO2 extraction from solids and liquids, high-pressure micronization (RESS/GAS), high-pressure sterilization and autofrettage, as well as pressure generation systems for ultra-high pressures up to 10'000 bar. The components are machined on CNC lathes; pressure vessels are made from austenitic and ferritic materials as well as nickel-based alloys. Customers come from pharma, chemicals, food/natural products and research and development. Production is located in Ebmatingen (ZH), headquarters in Maur (ZH).
