Our Technologies

Exhaust Air Technology

We develop and produce systems and plants for the efficient separation of industrial emissions.

  • Dedusting plants and units for the separation of industrial dusts (Fine dust filter, large dedusting systems, Compact filter units...)
  • Filter systems for the separation of mist and steam (oil mist separator, emulsion mist separators, release agent mist separators...)
  • Hybrid filter systems for the simultaneous separation of dust, aerosols and gaseous emissions and smells.

Ventilation Technology

We develop and produce systems and plants for industrial indoor air purification. Our solutions also efficiently and economically released large industrial halls from diffuse emissions and waste heat. The holisitc solutions include energy-optimized capture and separation of emissions, ventilation, heat recovery and air conditioning in production.

Energy Technology, Heating & Cooling

We develop and produce systems and plants that significantly reduce the energy requirements of ventilation systems and recover waste heat. Our holistic solutions enable an energy-efficient and comfortable heating and cooling of the hall. This reduces operating costs and increases resource efficiency significantly and measurably.

Linking of 
Ventilation Technology,
Exhaust Air Technology
& Energy Technik

We combine indoor air technology with exhaust air technology and energy technology in a unique way. The individual systems support each other and thus increase the function. Our years of experience and our unique know-how allow our customers to benefit twice: they receive a holistic solution with top performance, the acquisition and operating costs are lower than with standalone solutions.

Our Quality

QUALITY – That's 
our benchmark!

All departments of the company are involved to ensure the highest quality and to satisfy our customers.


We ensure quality with ...

  • Consistent design planning of our systems and processes in plant engineering and in the development.
  • Careful selection of components.
  • Defined entry, intermediate and final testings.
  • High-quality measuring technology.
  • Continuous improvement processes. They are based on the suggestions for improvement of our employees, defined quality assurance groups and the analysis of error messages.
  • Training, further education, training and one's own professional training (including apprenticeship training at the main plant in Linz).


We regularly review our strict quality standards in the course of internal and external audits. But mistakes can happen to us as well. Therefore, we work consistently and sustainably to eradicate and prevent mistakes.
