DW – double-walled stainless steel flue gas system,the classic
The double-walled flue gas system with thermal insulation and classic plug-in connection with external clamp band can be used for all standard fireplaces, including solid fuels, as well as for modern oil and gas fireplaces.
The element construction method allows fast construction progress and the large variety of components permits adaptation to the most difficult assembly situations.
The freely expandable inner shell, together with the 30 mm joint-tight heat insulation, guarantees low surface temperatures. The absence of these thermal bridges prevents cracking noises caused by temperature stresses during rapid heating.
The additional capillary stop incorporated into the outer shell ensures that no moisture can get into the heat insulation from the outside. The statically supporting outer shell with wide quick-release clamp fitting impresses with maximum stability even in difficult installation situations. By means of an easy-to-fit EPDM lip seal, calorific value boilers up to 120 °C flue gas temperature can be connected in positive pressure operation.
The WPG version in material 1.4539 for wood logs, wood pellets and wood chips is even approved for moist operation after a possible soot fire.
The extensive accessories with shaped parts for almost all situations, fixings, roof ducts, etc. round off the system perfectly.
