Description
• The 87° “T” fitting (Di 80 x De 130) with a reduced coaxial tail with air gap is characterised by the presence of a return grille in the lower part of the external diameter that allows the entry of combustion air necessary for combustion processes; the internal diameter performs the function of expelling the products generated by combustion.
• It is used as a fitting between the smoke duct and the chimney system; the insulation of the body in continuity with that of the chimney system guarantees efficiency and good operation with excellent performance and low emissions.
Features
• Internal Wall: Stainless Steel 316 BA (EN 1.4404 - L50) thickness 0.5 mm.
• External Wall: Stainless Steel 304 BA (EN 1.4301 - L20) thickness 0.5 mm or Copper thickness 0.6 mm.
• Insulation: Rock wool cups, thickness 25 mm, density 90 kg/m3.
• Welding: with TIG process, by fusion of adjacent edges without adding material.
Applications
• It is a component that allows the conveyance of air necessary for combustion and disposal of products deriving from combustion processes of condensing boilers.
• For the designation of the Chimney System according to the UNI EN 1856-1 Standard, the following is permitted:
• Operation:
- dry (D)
- wet (W)
• Pressures:
- Positive (P1 = 200 Pa)
- Negative (N1 = 40 Pa).
• Operating Temperatures:
- ≤ 200 °C with silicone gasket and P1 = 200 Pa
- ≤ 600 °C without silicone gasket and N1 = 40 Pa
