single wall system SJKB

The SJKB system is used to discharge flue gas from condensing boilers working in hypertension. Chimneys are designed to work in a wet environment. We make them of 0.5-0.6 mm thick steel, grade 1.4521.

They excel at a maximum temperature resistance of 200 degrees C. The system uses gaskets with possible temperature resistances of 120 degrees C and 200 degrees C. Chimneys are also very resistant to condensate.
