Wessel - Umwelttechnik

What Wessel - Umwelttechnik does

Wessel-Umwelttechnik GmbH is a Hamburg-headquartered industrial manufacturer founded in 1965 that designs and delivers custom turnkey exhaust air purification and heat recovery systems for enterprise customers. The company operates across four purification methodologies — biological, chemical, physical, and thermal — with a product portfolio that includes the proprietary BIOCAT family of bio-scrubbers, bio-reactors and biofilters (rated up to 99% VOC and odour removal efficiency), DCS exhaust and flue gas scrubbers, DLP dust scrubbers, Regenerative Thermal Oxidizers (RTO), We-SORB activated carbon adsorption units, and WERO rotary heat exchangers for energy recovery. Systems are engineered for volume flows from 500 to 1,200,000 m³/h and are deployed across automotive and tier-suppliers, chemical, wood-based panels, food and beverage, waste management, semiconductor, pharmaceutical, paint/coating and printing sectors.

The business generates revenue through three primary streams: (1) one-time turnkey plant sales covering design, fabrication, installation and commissioning; (2) recurring service, maintenance and 24/7 remote monitoring contracts on the installed base; and (3) spare parts and consumables (activated carbon, adsorption media, catalysts, biofilter materials), supplemented by emissions measurement and professional installation services. Pricing is project-based and not publicly disclosed. Go-to-market is direct enterprise field sales supported by a network of regional channel partners in France, Spain, Turkey, the USA, the UK, Romania, Central and Eastern Europe, and Southeast Asia, complemented by participation in industry trade shows such as Pollutec 2025 (jointly with CarboTech) and the planned FORMÓBILE 2026 in São Paulo.

Wessel-Umwelttechnik is a wholly-owned member of the Deurotech Group since 2015, alongside sister companies Vits Technology, IFA Technology, Eisenmann Environmental Technology, and Oschatz Power. The company holds ISO 9001:2015 certification and is approved as a specialist company under the German Water Resources Act (WHG), with engineering explicitly designed to comply with TA Luft, BImSchV, WGC-BREF, and GIRL frameworks. Over 800 custom exhaust air cleaning systems and more than 150 heat recovery systems have been installed to date, and the company supports more than 1,000 exhaust air treatment systems globally. Management comprises Werner Deuring (Chairman), Lars-Uwe Iwers (CEO), and Jörg Rossius (CTO); headcount is in the 11-50 range with no disclosed funding, M&A, or revenue figures.
