Simple manufacturing of flexible, metallic chimney liner ducting
Flexible flue ducts are used in flue and chimney technology, particularly for chimney renovations (e.g. in the event of chimney sooting) or when it is necessary to reduce the cross-section of existing chimneys. They are extremely elastic and pliable, which makes them very flexible. Existing offsets in the masonry chimney or even slanted ducts do not pose a problem when renovating a chimney with flexible ducting, as the ducts adapt flexibly to the structural conditions on site.
Flexible flue ducts manufactured with HAFLEX duct winding machines are typically suitable for all fuel types (oil, gas and solid fuels), resistant to moisture, extremely corrosion-resistant and soot fire-resistant.
On site, the flexible ducts can be simply connected using special connectors or easily combined with other fixed fittings.
You can produce all the flexible ducts required for a chimney renovation yourself with HAFLEX duct winding machines; in your warehouse, in your own workshop or even in a vehicle on site! Flexible ducts made with HAFLEX duct winding machines lead the way in terms of technology and quality and set the standard in markets worldwide.
