SKD – DOUBLE WALLED CHIMNEY SYSTEM

Darco system

SKD – DOUBLE WALLED CHIMNEY SYSTEM

Designed to construct selfstanding chimneys extracting fumes from gas and oil boilers.

Double walled chimney system is used for building chimneys and chimney ducts made of stainless steel, taking out wet fumes from oil and gas boilers working with negative pressure. Chimneys are build with the inner pipe made with 1.4404 (acc. to DIN17441) stainless steel, outer pipe – 1.4301 (acc. to DIN17441), thermal insulation – mineral wool, thickness 50mm.

Advantages:

  • acid-resistant, especially against sulphuric acid
  • much lower resistance of fume flows in comparsion to traditional brick chimneys, because of small roughness of the surface
  • possibility of applying chimney with buildings with no traditional brick chimney
  • wide possibilities of system configuration
  • wide range of products, possibility of making non-standard products

Usage

  • to construct selfstanding chimneys extracting fumes from gas and oil boilers
