DW-VISION Chimney System

The DW-VISION system – a double-walled flue gas extraction system – consists of smooth-walled pipes and fittings made of stainless steel, with a minimum wall thickness of 0.5 mm for the flue pipe and 0.5 mm for the outer jacket. The system components are thermally insulated with 32 mm thick mineral wool, tightly fitted to the flue core and outer jacket. This technical solution prevents the formation of harmful thermal bridges that conduct heat from the flue core to the outer jacket. The unique connection of the outer casing, manufactured using compression technology, ensures the chimney’s high aesthetic appeal, enhancing its visual qualities. This solution also guarantees good structural integrity without the need for clamping bands. The DW-VISION system is available in diameters ranging from 100 to 250 mm. Longitudinal welds are made using plasma cutting with shielding gases or laser cutting. Individual components are connected to one another via a push-fit system using sockets. The system is designed for use with heating appliances featuring an open combustion chamber, operating under negative pressure in dry or wet mode, and fuelled by gas, fuel oil or solid fuels. It is also suitable for use as a ventilation system. It can be installed both inside and outside the building, and a wide selection of chimney fittings, ceiling brackets, wall brackets and wall consoles ensures easy and stable installation of the chimney to the building wall or supporting structure.

Scope of application – as a double-walled flue gas extraction system designed for combustion chambers operating under negative pressure, in dry or wet mode, fuelled by gas, fuel oil or solid fuels, e.g. bakery ovens, gas and oil-fired boilers, and fireplaces.
