Wessel-Umwelttechnik GmbH

Wessel-Umwelttechnik GmbH, founded in 1965 and based in Hamburg, Germany, designs and builds turnkey industrial exhaust air purification and heat recovery systems. An ISO 9001:2015-certified company and member of the Deurotech Group, Wessel-Umwelttechnik has delivered over 800 custom air purification installations and more than 150 heat recovery systems across biological, chemical-physical, and thermal treatment technologies. The company's product range spans four principal process families: biological systems including the WERO Biowäscher-Reaktor bioscrubber and biofilters for biodegradable pollutant streams; absorptive gas scrubbers handling acid gases, ammonia, and formaldehyde; adsorption units employing activated carbon or alternative media for solvent and VOC capture; and thermal oxidisers including regenerative and recuperative afterburners for high-concentration organic emissions. Complementing the purification portfolio, Wessel-Umwelttechnik's heat recovery installations capture thermal energy from exhaust streams to reduce fuel consumption and CO2 output. The company targets pollutants including VOCs and solvents, odorous compounds, particulate dust, ammonia, formaldehyde, and acid gases, serving sectors such as automotive supply, chemicals, wood-based panel manufacturing, food and beverage, printing, feed production, wastewater treatment, and paints and coatings. Wessel-Umwelttechnik provides full lifecycle support from initial consulting and engineering through manufacturing, commissioning, and ongoing service and maintenance, emphasising high plant availability and operational safety.
