FILTER PROCESS EXHAUST AIR. UTILIZE WASTE HEAT.
Electrostatic precipitators, wet scrubbers, carbon, UV light, biofilters and more – we combine the processes that fit your requirements and recover the heat.
Industrial Exhaust Air Filtration with Heat Recovery
KMA develops and builds systems for exhaust air filtration and heat recovery for energy-intensive industries.
We are familiar with the exhaust air of many industries and always consider emissions, energy and waste heat together. From our process modular system, we assemble exactly the solution that fits your process.
Your advantage is evident every day in operation: lower energy and gas costs, reliably maintained emission limit values and low maintenance effort.
Inside, the indoor air quality in the production hall improves. There is less smoke, oil mist and dust – good for employees and machines. Outside, the environment and neighborhood benefit from lower emissions and fewer production-related odors.
Smoke, aerosols, grease, oil, odors or volatile organic compounds (VOC): We combine the filter stages that reliably bring your exhaust air below the limit values. This secures your permit, occupational health and safety and your location.
Electrostatic precipitators require little electricity, heat exchangers recover energy from the exhaust air, and automatic cleaning saves maintenance. This reduces your energy and operating costs over the entire service life.
Our systems clean the exhaust air without thermal oxidation and entirely without natural gas burners. This reduces your gas consumption and makes your calculation more independent of the gas price and CO₂ tax.
Fewer emissions, proven with measurable values: This strengthens your position in bank meetings, customer audits and supplier evaluations – everywhere where ESG criteria help determine conditions and contracts.

INDUSTRIES
Energy-intensive & high-emission? No problem!
One topic, many industries – and always a suitable solution.
Whether textile industry, foundries, food industry or particularly complex challenges:
We have the solution for a wide variety of industries and applications.
Their common denominator: they are all energy-intensive and high-emission. That is exactly our specialty.
See for yourself and challenge our experts. We look forward to your inquiry.
Clean production hall? Improved energy efficiency?
Metal processing generates emissions such as mould-release agent mist or oil smoke, which must meet strict occupational health and safety and certification requirements. As an expert in energy-efficient environmental technology, KMA offers tailored solutions for smoke extraction, exhaust air filtration, and heat recovery.
- Meets statutory limit values and certification requirements
- Improves air quality and energy efficiency at the same time
- Tailored solutions for the metal industry

Replace thermal oxidation? Odour problem?
Greasy, warm exhaust air with VOC content is typical in food production and poses challenges for operators in terms of permits, emissions, and sustainability goals. Instead of energy-intensive thermal oxidation, KMA relies on process-adapted exhaust air filtration combined with heat recovery – for less odour, lower costs, and greater energy efficiency.
- Reduces odour levels
- Saves energy costs compared to conventional thermal oxidation
- Actively uses warm exhaust air for heat recovery

Expensive exhaust air filters? High maintenance effort? Odour problem?
In plastics, silicone and rubber processing, emissions and odors often occur as particulate-laden, VOC-loaded exhaust air. Regulatory requirements are getting stricter. Customer sustainability demands and complaints from neighbors add to the pressure on manufacturing companies.
Thermal oxidation is effective, but often energy-intensive and costly.
KMA designs solutions that fit your process: smoke extraction, filtration, air filtration concepts and, optionally, heat recovery. The result is stable operation, measurable relief for the environment and the workplace, and lower energy costs.
Our plastics expert is happy to advise you. Where do you want to start: cutting CO₂, improving energy efficiency or reducing odor?

Improve energy efficiency on the stenter frame? Cut CO₂ emissions?
Textile processing produces emissions and odors, often laden with oil, fiber and wax particles. At the same time, energy costs for the gas-fired stenter frame are a major driver of production costs.
KMA uses the hot exhaust air streams as a valuable energy source, either to preheat the supply air or for use in downstream processes.
Depending on your needs, we integrate air-to-air, air-to-water or combined heat exchangers. The integrated cleaning system for all modules of the filter system ensures long-term performance.
Want to reduce your gas consumption or upgrade your exhaust air treatment? We will review the options with you.

Your industry isn’t listed?
Many processes produce emission-intensive exhaust air, and every situation is different: dust, aerosols, VOCs, odour, heat content, fluctuating volume flows or sensitive production environments.
KMA starts with a structured assessment of your exhaust air flow (emissions, temperature, volume flow, target values). From this, we develop a suitable concept for smoke extraction, filtration and, where it makes sense, heat recovery. This gives you reliable compliance with emission limits, clean production areas and better energy efficiency.
Briefly describe your process to us. Our sales support team will put you in direct contact with the right specialist team.

Technology & Solutions
Our modular system for industrial exhaust air filter systems
exhaust air and energy. Engineered together.
Our solutions combine high energy efficiency with maximum separation performance and convenient maintenance. Whether emissions, volatile organic compounds (VOC), particles, smoke or odors: our comprehensive industry knowledge and process expertise result in a solution that fits your requirements exactly.
Four KMA performance promises apply to all our technologies:
- high energy efficiency
- effective exhaust air filtration
- powerful heat recovery
- integrated cleaning
At the center of our process technology are the ULTRAVENT® and AAIRMAXX® electrostatic precipitator product lines. Configurable for volume flow rates from 1,000 to 200,000 m³/h, they can be flexibly supplemented with heat recovery and additional modules for enhanced odor filtration or separation of VOC. This allows you to achieve up to 99% separation performance while simultaneously benefiting from noticeably lower energy and operating costs.
Are you hesitating with your investments? All the better if they pay off.
Environmental technology is subsidized.
For KMA systems, subsidy programs typically address three points:
Energetic optimizations
Replacing thermal emission treatment with natural gas
Heat recovery from contaminated process exhaust air for energy efficiency

Frequently Asked Questions
KMA Umwelttechnik — FAQ
What does KMA Umwelttechnik do?
KMA Umwelttechnik is a solution provider for industrial process exhaust air. KMA considers emissions, exhaust air and energy together because they are in the same air stream. From this perspective, KMA selects the processes that fit the process, for example electrostatic precipitators, wet scrubbers, carbon, UV light or biofilters. The system complies with the limit values and recovers the heat from the exhaust air. The company is based in Königswinter and works primarily for the food industry, foundries and plastic processing.
Do I have to clean my process exhaust air, and which limit values apply?
Generally yes, because industrial plants must comply with emission limit values. In the EU, the BAT conclusions from the BREF documents define the state of the art for the respective industry. The member states implement them into national law, in Germany via the Federal Immission Control Act and the TA Luft. Outside the EU, the national or regional regulations of the respective country apply. The specific values are determined by the responsible licensing authority for your location. KMA designs the system according to the legal requirements applicable there and, on request, accompanies the official measurement.
For which industries and processes does KMA build exhaust air filtration?
KMA provides exhaust air filtration with heat recovery for processes in which smoke, grease, oil, tar or odors are generated in the exhaust air. Focus areas are the food industry, metal processing with foundry, die casting and melting furnaces, textile finishing as well as plastic and rubber. Where a standard device is not sufficient, KMA develops special systems for the individual process. For production halls, KMA plans the overall concept in which extraction at the source, filtration, supply air and heat recovery interlock. The industry pages show what this looks like for the respective process.
