- Exhaust gases evacuation from of all types (fireplaces, stoves, boilers in single or collective systems, thermal power plants …), from 40 ° C in conditions of high condensation to temperatures higher than 700 ° C, and beyond, in the presence of strong dilations, also resistant to thermal shock from soot fire at 1000 ° C
- Aspiration and evacuation of vapors for professional kitchen sector for catering and air exchange in public buildings with the need to keep noise levels and the presence of condensation to minimum.
With theDOUBLE WALL DP25 CANNA srl it is possible to obtain a notable improvement in the exhaust conditions of the flue gases, thanks to the designed technical and constructional characteristicsof the CE UNI 1856-1certified product.
The speed and temperature of the exhaust gases, higher in the double wall (as also demonstrated by the analysis of the finite elements of the distribution of the temperatures), facilitate the evacuation of the gases, reducing the formation of acid condensate, harmful to the system, and soot build-up.
The absence of closing flanges allows to eliminate harmful thermal bridges between internal and external wall to the advantage of insulation; the consequent double joint of 50 mm, both for the external and internal wall, hinders possible infiltrations from the outside and improves mechanically the joint ensuring superior mechanical strength, for greater resistance to loads such as wind or cantilever elements.
The DP50 series is distinguished by the increased thickness of the insulation, from 25 to 50 mm, and is applied for the evacuation of gases from particularly high temperatures and for the larger diameters of the series, greater than D300, with compensation for the relative dilations .
