SYSADVANCE - Sistemas deEngenharia SA

SYSADVANCE — Sistemas de Engenharia SA is a Portuguese engineering company headquartered in Póvoa de Varzim that develops and manufactures on-site gas generation and purification systems serving industrial, medical, and energy sectors worldwide. The company operates across three divisions: Industrial, Medical, and Energy. In the Industrial division, SYSADVANCE produces PSA-based nitrogen and oxygen generators plus helium purification systems. The Medical division supplies oxygen generators, medical air, and vacuum systems for healthcare facilities. The Energy division — most relevant to water and waste applications — delivers biogas upgrading and gas treatment technology. Its flagship METHAGEN AD system uses proprietary VPSA (Vacuum Pressure Swing Adsorption) technology to purify biogas from anaerobic digestion feedstocks including wastewater treatment plant sludge, food and organic municipal waste, and agricultural waste. The METHAGEN LF system is specifically engineered for landfill gas upgrading, with high nitrogen and oxygen removal capacity to produce high-BTU renewable natural gas from gas streams that challenge conventional upgrading systems. The CARBOGEN platform addresses carbon capture and utilization, purifying CO₂-rich gas streams at capacities from 100 to 1,000 Nm³/h. The BiOxygen system produces pure oxygen via PSA molecular sieve technology for injection into H₂S reduction processes such as digester dome aeration, iron sponge units, and bioscrubbers — injecting only O₂ to avoid biogas dilution with contaminants. SYSADVANCE provides full turnkey project delivery, maintenance and after-sales service, equipment rental, and R&D consulting.
