separate pressured solar collector

solar collector The pipeline is made of red copper and conducted by heat transfer medium liquid. Water cannot flow in vacuum tubes and operated when confined. The crust uses aluminum alloy mould material of high strength with air flow design. It is furnished in good style. Can endure high pressure when it works. Module design, optional combination, which can meet the demand of large water consumption. * Material: Aluminum alloy* Solar vacuum tube withcopper pipe a) Size: 58 x 1,800mm b) Qty of tube: 10-30pcs c) Hail resistance: diameter 25mm* Insulation layer in chest a) 50mm thickness imported polyurethane, machinery overall for keeping same temperature and high pressure foam b) Heat preservation: 72 hours* Max. pressure bearing: 0.6MPa* ISO9001:2008/CCC / CE certificate* 3 years international responsibility for free repairing or exchange due to original quality problems1, Manifold : red copper 2, Manifold Casing: aluminum alloy 3, Glass tube dimensions: 58mm x 1.8m 4, Heat preservation: 72hrs 5, Hail resistance: 25mm 6, max pressure: 10 bar 7, working pressure: 6 bar 8, Coating of vacuum tube: SS-C/CU 9, Heat Pipe: anti-freezing > -35°C
