Pressure solar collector

KUP58 solar collector mainfold is made of 100% aluminium: 1)The pipeline is made of all the red cooper and conducted by heat transfer medium liquid. 2)The crust uses aluminum alloy mould material of high strength with air flow design. 3)We do treatment in high pressure vessel with chemical treatment for better performance. 4)It can withstand high pressure when it works. 5)Modern design, arbitrary combination, which can meet the demand of large water consumption. Name: Pressurized Solar collector Model: KUP58-20 Features: 1)Vacuum tubes: Heat Pipe vacuum tube, 58x1800mm in length with 14mm or 24mm condenser, which gives the best heating efficiency. 2)Inner material of mainfold: Red copper flow channel 3)Outer material of mainfold: Aluminum alloy,other materials can be made also. 4)Frame material: Aluminum alloy.Stainless steel and galvanized steel can be made also. 5)Available sizes: 10, 15, 18, 20, 24, 25, 30, 36, 2X15, 2X20, 2X25, 2X30 tubes 6)Pressurized water tank: 100L, 150L, 200L, 250L, 300L, 400L, 500L Technical data: total length (m)1,65/2,00/ 2,45Total Width (m)1.9Gross Absorb Area (m²)3,14/3,80 / 4,66Appeture Area (m²)2,52/3,36 / 4,20Surface dabsorbeur (m²)2,18/2,42 / 3,03ReflectornonOperation Pressure (bar)8Entry Connector size½ male/ copper tubediameter of condensor(mm)24Material of ManifoldAnodized Aluminum 2mmMaterial of Heat pipe and Manifold HeadTU1 CopperInsulation of manifoldpolyurethaneSlot of thermic sensoryesCold Resistance-30liquid capacity1.4/1,8 / 2,2total weight (kg)39/47 / 65mini. flow (l/m)120typical flow (l/m)150max. flow (l/m)600stagenation temperature (°c)300EN 12975 (Solar Keymark )in courseDateOct-15Efficiency (n0 in %, k1 in W/m²K, k2in W/m²/K²);n0= 0.77, k1 = 1.47, k2= 0.0051hail resistance=<25diameter of tube (mm)58Glass qualityBorosilicate3.3 (T=0.91)thickness (mm)1.7vacuum degree (Pa)3x103absorb rate=>0.94reflecting emission<0.06material of coatingSS-C/CU
