Material type Insulation material: Synthetic EPDM rubber based foam. Corrugated stainless steel hose: Austenitic stainless steel, according to EN 10088-2: X2CrNiMo 17-12-2 and DIN 17441: 1.4404. Covering: Polyolefin copolymer film. Colour Black Material special information The return pipe includes a temperature sensor cable (2x0.75mm2 ) with halogen-free, temperature resistant silicone coating (+180˚C). Applications Tubing system to connect solar collectors with solar thermal hot water cylinders. Remarks The solar system and heat transfer fluid has to be well matched in order to guarantee corrosion and interference-free operation. We recommend an annual laboratory test of the fluid medium (density, concentration, pH). The heat transfer fluid has to be completely replaced in case the parameters no longer meet the requirements EC Certificate of Conformity no. 0543 of Güteschutzgemeinschaft Hartschaum e.V. , Celle Property Value/Assessment Test Standards & Remarks Temperature Range Max service temperature +150˚C EU 5670 Tested acc to EN 14706 & EN 14707 Min service temperature -50˚C Thermal Coductivity λ 40˚C ≤ 0.042 W/(m·K) [36.92+0.125⋅ ϑm + 0.0008⋅ (ϑm -30)2 ]/1000 EU 5670 Declared acc. to EN ISO 13787 Tested acc. to EN ISO 8497 Water Vapour Diffusion Resistance μ ≥ 4000 EU 5670 Tested acc.to EN 13469 Fire Performance Reaction to fire Euroclass E EU 5670 Classified acc. to EN 13501-1 Tested acc. to EN ISO 11925-2 Other technical features Dimensions & tolerances In accordance with EN 14304, table 1 EU 5670 Tested acc. to EN 13467 Chemical behaviour Excellent resistance to ozone, chemicals (consult product test list) and building materials UV resistance Good Health aspects Dust and fibre free Max operating pressure (bar) ODP zero GWP zero EU 5197 Pipe volume (I/m) CU12 = 0.085 DN16 = 0.272 CU15 = 0.141 DN20 = 0.430 CU18 = 0.201 DN25 = 0.633 ArmaFlex DuoSolar is a flexible pre-insulated, UV resistant insulation system used to connect solar collectors with hot-water storage tanks.
