EW – Single-walled stainless steel flue gas system, the specialist for modernization
The single-walled, humidity-insensitive Raab EW system is the proven system for installation in existing chimneys when converting to new heat generators. In addition to chimney refurbishment, it is also ideally suited for installation in Raab lightweight shafts for new flue gas systems to be constructed in the building. In addition, Raab EW can be used for connecting pipes.
A wide variety of fireplaces can be connected, whether chimney or tiled stoves, boilers for oil, gas, wood, wood pellets or condensing boilers for oil or gas. As a WPG version in material 1.4539 for wood logs, wood pellets and wood chips, the EW system is even approved for humid operation after a possible soot fire.
The easy-to-install system with 80 mm long plug-connection has high longitudinal stability and, thanks to its small external dimensions, allows installation even in narrow existing chimneys. For operation in overpressure different seals are available depending on the application.
Raab EW is available in wall thicknesses of 0.6 mm and 1.0 mm and can be combined with the flexible flue gas systems. A comprehensive range of accessories with matching flue gas silencers, adapters for Kutzner + Weber draught regulators and fine dust particle separators round off the product range.
