TwinCoveral

Screen 2015-01-13 to 17.33.39

It is the copper pipe coated with insulating agents that employ an innovative and completely recyclable polymer compound characterized by high thermal insulation performance.
In addition, its permeability steam factor is μ≥11.000 which, together with its heat conductivity coefficient (λ=0,038 W/(m*K) and its perfect adherence to the copper tubing ensure maximum anti-condensation performance.
The polyethylene foam is produced without hazardous substances (CFCs and HCFCs) in compliance with the European Community Regula- tion No. 237/2000 and with the Directive 2011/65/EU (RoHS).

Outer UV blocking film in aluminium
An outer film in aluminium protects the insulation from direct sunlight and other atmospheric agents, in order to make the pipe live longer. The seals of the heads at a pressure of over 70 tons ensure the perfect inner cleanliness of the aluminium tubes.
All the above certified characteristics and the special production process regulated by in-house specifications in compliance with the Standard UNI EN ISO 9001 :2015 make our product suitable for all the systems installed in compliance with the Italian Ministerial Decree No. 37/2008.
TwinCoveral is available in 20m coils. The pipe is marked at one-meter intervals.
