Double wall chimney systems for boilers, fireplaces and extractor hoods

The twin-wall STABILE RPD flue system can be used for every kind of civil or industrial generator working with gas, liquid and solid combustible (engines and power units only after verification and sizing by our Technical Dept.). The STABILE RPD system is certified for combustion products having a max temperature not exceeding 200°C with mounted gasket and a max temperature not exceeding 600°C without gasket. The STABILE RPD system is suitable for being installed as chimney and as collective chimney, in compliance with the current national regulations. In locations where the atmosphere is rich in halogen fumes, we do not recommend the use of stainless steel chimneys (laundries, dye works, printing works, and hairdressings). The usage of these products in such locations voids the manufacturer’s warranty.
