OLIFlex S.P. INOX
Channel and conduit for air conditioning system / flue
OLIFlex S.P. Inox, a single-wall system in stainless steel AISI 316, is designed to be installed inside ducts, in old chimneys or in the cavities of new buildings. As well as removing the combustion products it is also used for discharging the vapour produced in both civil and industrial kitchens to the exterior. The UNI and EN standards on chimneys do not allow the installation of single-wall systems outside the building but only inside central heating systems and in closed areas. All flue systems belong to the Construction Products category and must display the CE mark in compliance with the Construction Products Directive 89/106/CE of 21/12/88. The single-wall systems in stainless steel are CE marked in compliance with European Standard UNI EN 1856/2 whereas the double-wall chimney systems with insulation are CE marked in compliance with UNI EN 1856/1. The connection pipes and flue pipes must also be CE marked. To be CE marked the chimneys/flue pipes/conduit pipes must undergo some very rigorous testing, such as: corrosion resistance, (V1 - V2 - V3) pressure, (N1 - P1 - H1) heat tests to determine the maximum working temperature, (T200 - T600) soot fire resistance, (G - O) and minimum distance to combustible material (xxx), this is indicated by the producer for double-wall systems. The other tests to be carried out are as follows: condensate resistance (W) and resistance to rainwater, mechanical tensile and compression tests and wind tests.
