What Tholander exhaust technology does
Tholander Ablufttechnik GmbH is a privately held German engineering company founded in 1986 that designs, manufactures, and installs custom-tailored exhaust air purification systems for industrial and municipal customers. The firm relocated its headquarters to Weinheim (near Heidelberg) in 2026, having previously operated from Viernheim (since 1991) and originally Hemsbach. With a workforce of 11-50 employees, Tholander positions itself as a focused specialist in odor removal and air pollution control rather than a broad-line environmental equipment vendor.
The company's product portfolio comprises six complementary technologies: biofilters (biological odor removal using microorganisms), counter-current scrubbers (wet separation with claimed >99% efficiency), crossflow scrubbers (multi-stage wet scrubbing), multi-venturi scrubbers (dust separation), biotrickling filters (hybrid biological treatment), and activated carbon filters (adsorption-based fine cleaning). Systems are fabricated in-house from glass-fibre reinforced plastics (GRP) for corrosion and chemical resistance, supported by ISO 9001:2015 certification. The installed base exceeds 800 reference projects across more than 40 countries, serving waste treatment, wastewater treatment, chemical, food processing, tobacco, and animal processing verticals. Managing Director Thomas Pfliegensdörfer leads the firm.
Tholander monetizes through project-based sales of customized exhaust air purification systems combined with ongoing engineering, maintenance, and service contracts. Go-to-market relies on direct enterprise field sales supplemented by a network of regional representatives across 40+ countries, with project execution spanning planning, in-house production, installation, and worldwide maintenance. Customer acquisition is driven by international trade fair participation (IFAT Munich, IWA, EXPOAPA), German government-sponsored trade delegations, and institutional partnerships such as German Water Partnership and AHK Eastern Africa.

Products and services
- Biofilter Sustainable biological odor removal system that uses microorganisms to break down pollutants in exhaust air at ambient temperature and neutral pH. Cost-effective solution for low-concentration, odor-intensive exhaust air streams from industrial and municipal facilities.
- Counter-Current Scrubber (Gegenstromwäscher) Wet separation system for removing harmful compounds from exhaust air via physical or chemical absorption through counter-current flow in a packed column. Achieves >99% separation efficiency with low space requirements for heavily polluted exhaust air.
- Crossflow Scrubber (Kreuzstromwäscher) Compact multifunctional scrubber where exhaust air flows horizontally through a packing bed in cross-flow with scrubbing liquid. Multi-stage configurations enable simultaneous removal of dust, acidic, and alkaline components in a single housing.
- Multi-Venturi Scrubber (Multiventuriwäscher) Wet dust separation system using the venturi principle with automatically cleaned separator elements. Handles humid, hot, and dusty exhaust air with automatic blow-down, rinsing, and discharge functions for dusty emissions from processes with strong-smelling compounds.
- Biotricklingfilter Space-saving biological exhaust air treatment combining biofilter and counter-current scrubber principles. Uses a trickle bed with biofilm-covered carrier material and controllable environmental conditions for efficient pollutant decomposition.
- Activated Carbon Filter (Aktivkohlefilter) Adsorption-based fine cleaning system using activated carbon's large inner surface area to attract and bind odor molecules. Effective for H2S-laden air from sewers and wastewater treatment plants, achieving high separation efficiency even at humidity levels up to 98% without chemical use.
