Synthetic gas flue systems
Raab synthetic gas flue systems can be used for versatile applications, especially for modern heat generators with high efficiency such as condensing boilers or mini and micro combined heat and power units (CHP).
Single-walled and flexible flue pipes are available for installation in chimneys or shafts for gas flue pipes.
The concentric pipes and fittings, powder-coated white, are used for connecting pipes for independent of ambient air operation.
For room-air-independent fireplaces, the combustion air is drawn in from outside through the annular gap.
The concentric PPs/VA system has an outer shell made of high-quality, high-gloss stainless steel for mounting on the facade.
Numerous components and the extensive range of accessories ensure simple planning and rapid construction progress.
