Innovation – Environment – Human

The legal requirements for environmental compatibility and functionality of flue gas systems are constantly changing. The limits for flue gas emissions are routinely tightened by the legislator. With our chimney components, you can master these challenges.

Our Kutzner + Weber chimney components reduce flue gas emissions, for example fine dust, and increase the efficiency of the flue gas system. They optimize combustion, reduce noise and thus make flue gas systems more environmentally friendly, more energy efficient and also more convenient to operate. Thus, these are equipped for the future.

Our product range includes fine dust particle separators, Draught regulators, flue gas dampers, silencers, chimney fans and other chimney accessories.
