Z-DENS
™
(D) roof terminals are especially designed
for connection to non-condensing boilers with a
maximum flue temperature of +160°C (+320°F)
(T160).
Z-DENS
™
(D) roof terminals are available in two versions:
• Concentric 2’/3” (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
™
(D) roof terminal is made of
plastic (UV resistant).
• The cover on top of the cap is made of aluminum.
• Outer pipe below is made of galvanized steel.
• Flue pipe is available in aluminum.
• 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 newly designed cap introduces some interesting technical
