SKSPD-X- insulated air-flue chimney system

System for modern, condensing gas boilers.

skspd_wiz

Insulated air – flue systems are used to exhaust fumes from modern condensing boilers, which use the effect of vapor condensation in the combustion process, or from “Turbo” type of boilers, with closed combustion chamber, that use a ventilator to exhaust fumes (positive pressure chimney duct). They are used for building self-standing chimneys that will be resistant to destructive influence of chemical substances which are a part of the fumes.

In this system, air necessary for combustion process is taken from outside with the usage of the outer pipe – that is why ; SKPSD-X systems are built with triple walled elements (two pipes axially placed and thermal insulation of 50 mm with outer casing). Construction of the systems allows fume exhaustion to be made through inner duct while air supply is made through the gap between inner and outer duct.

Advantages:

  • high acid resistance
  • very durable
  • wide system configuration possibilities
  • non-flammable material
  • high chimney tightness
  • to build self-standing chimneys extracting fumes from modern, condensing gas boilers

Usage
