About ENTECCOgroup
ENTECCOgroup GmbH & Co. KG is an owner-managed corporate group in environmental technology with a focus on air pollution control. The group's companies manufacture filter products such as flat bag filters, vertical bag filters, compact filters, cartridge filters, round filters, cyclones, wet scrubbers and dry sorption systems, and from these create turnkey systems for dedusting, exhaust gas cleaning as well as ventilation and air extraction. The range of services also includes surface technology and painting systems, coolers and heat recovery systems, conveying technology, piping construction, silos, fans as well as engineering services including 3D planning, laser scanning and flow simulation. Projects follow a four-phase model (BASIC, DESIGN, BUILD, CARE) with service across the entire plant life cycle. Customers include industries such as foundries, the aluminium and copper industry, steel, energy (biomass, waste-derived fuel, refuse incineration and combined heat and power plants), wood, asphalt as well as stone and earth. The headquarters and production of GARANT-Filter GmbH are located in Lahr/Schwarzwald; further production in Gaspoltshofen (Austria) and Winston-Salem (USA) as well as branch offices in Zielona Góra (Poland) and Bangalore (India).

Materials & Processes
Stainless steel
Use e.g. in systems for asphalt mixing plants and stainless steel foundries.
Steel
Base material for filter housings, silos, pipework and conveying technology.
Aluminium
Use in systems for melting furnaces, UBC recycling and grinding dust extraction in the aluminium industry.
Copper
Use of the sorption systems in the secondary production of non-ferrous metals such as copper.
Glass fibre (filter material)
Filter material, among other things in oil-resistant HEPA filters (H13) for machining emissions.
Dry sorption (hydrated lime, sodium bicarbonate, activated carbon/coke)
Removal of HCl, HF, SO2/SO3, dioxins, furans and heavy metals in flue gas cleaning.
