The DW-Vision is a double walled design chimney on the highest architectural level, which offers a high quality and well thought through functionality. Thanks to its cylindrically retracted male couplings in the outer pipe, the DW Vision needs no clamp fitting between the elements and thus creates a flat tubular column. Together with the brushed stainless steel surface, this creates a real eye-catcher for every building. The DW Vision is a double-walled, soot fire resistant, isolated chimney or exhaust system made of stainless steel. The DW-Vision can be used for standard furnaces in which the exhaust gases are produced by burning gas, heating oil or solid fuel (natural wood, coke, peat or coal). The system can be used for dry as well as humid operation or the outlet of exhausts with negative pressure. Thus, it can be flexibly used for different areas.
