SILOXA ENGINEERING AG
About
SILOXA Engineering AG is a family-owned, independent German company founded in 1998 and headquartered in Essen, specializing in gas purification, conditioning, and drying systems for biogas, sewage gas, and landfill gas. With over 25 years in the market, SILOXA positions itself as a leading authority in biogas conditioning and purification, serving farmers, technical operators, OEMs, and international distributors. The company's activated carbon adsorber product line includes the mobile MAKA series (MAKA 200, 700, and 1100) with plug-in/plug-out cartridge exchange covering nominal flow rates from 40 to 650 m³/h, plus HD pressure variants for elevated operating conditions. The stationary FAKA series handles higher raw gas loads with gravity discharge for on-site carbon refilling, available in twin-chamber K2 configurations for extended service intervals. The GRW gas purification and heating system combines the MAKA platform with gas heating for targeted removal of siloxanes and hydrogen sulfide from digester gases. SILOXA's conditioning and drying portfolio includes dual-filter adsorption dryers, gas coolers, and the PowerDryer unit for gas dehumidification. The company also supplies a comprehensive range of activated carbon products — from standard grades to specially developed high-performance formulations with superior contaminant absorption and reduced self-ignition risk, including iron-based products for H₂S removal. Full-service support encompasses activated carbon consultation, delivery, exchange (plug-in/plug-out or on-site), and spent carbon waste management through the Rundum-Service all-inclusive package.
Key Products
Stationary activated carbon adsorption system for higher raw gas loads and volume flows, featuring gravity discharge for on-site carbon exchange and available in twin-chamber (K2) configurations for extended service life.
Portable activated carbon adsorption system with quick plug-in/plug-out exchange for clean carbon swap, available in three sizes (MAKA 200, 700, 1100) handling 40-650 m³/h nominal flow, with HD variants for higher operating pressures.
Combined gas purification and heating unit based on the MAKA platform, specifically targeting organic silicon compounds (siloxanes) and H2S removal from biogas streams.
Complete gas conditioning equipment including adsorption drying systems with dual-filter design, gas cooling units, and PowerDryer units for dehumidifying and preparing gas for downstream utilization.
Dual-filter adsorption dryers that remove moisture from biogas, sewage gas, and landfill gas to protect downstream CHP engines and meet gas quality specifications.
Gas coolers that reduce gas temperature to condense out moisture and prepare gas for further treatment or utilization.
