The insulated element is designed to remove flue gases from unheated straight sections of the chimney. Important! Due to the sockets, the useful length of the element is 60 mm shorter than the nominal length. The inner contour is made of 0.5 mm thick AISI430 stainless steel. Thermal insulation is made of basalt wool, which minimizes condensation and promotes rapid heating of the chimney duct and system startup. Cold-formed socket joints provide ideal geometry and gas tightness. Laser butt welding ensures a thin and durable seam, significantly increasing the service life. Operating temperature up to 450°C.
