Roof Terminals
Z-DENS
™
(W) roof terminals are specially designed
for connection to condensing boilers with a
maximum flue temperature of +120°C (+248°F)
(T120).
Z-DENS
™
(W) roof terminals are available in two versions:
• Concentric 2”/4” (Ø60/100) and 3”/5” (80/125 mm.)
• Parallel (twin-pipe) 2”/2” (Ø60/60) and 3”/3” (80/80 mm).
Specifications:
• Upper roof part of the Z-DENS
™
(W) roof terminal is made of
plastic (UV resistant).
• Outer pipe below roof is made of galvanized steel.
• Flue pipe is available in PPs, aluminum and stainless steel.
• Upper roof part is available in the colours black RAL 9005 and
terracotta RAL 8023.
• Outer pipe below roof is available in the colour white
RAL 9016, other colours upon request.
Cap
The new design of cap introduces some interesting technical
features.
Icicle-free
The cap allows rainwater to come in. The advantages
being:
prevents icicle formation,
allows dilution of condensate.
Aerodynamics
Its aerodynamic behaviour is outstanding!
Very low influence of wind on top of the K-value.
Suitable for all outlet areas.
