Chimney System

RTKMono Deco double wall chimney systems are usually used for fireplaces, heating, steam, and hot oil boilers and for process or hood systems, through which high-temperature gases flow. The system is double-walled and monoblock; rock wool insulation is inserted between the walls. It has low thermal conductivity, since the heat of the chimney gas is not considerably transferred to the environment, the chimney efficiency is high. It is manufactured with continuous TIG or PLASMA welding. The chimney connections are male-female joints and tightened with a stainless steel clamp from outside. The system is designed to compensate for the expansion of the inner wall due to high chimney gas temperatures. The chimney modules are manufactured in standard diameters between Ø80mm to Ø1200mm.
