Solar heater collector

Solar heater collector Feature: The pipeline is made of all the red copper and conducted by heat transfer medium liquid. Water can not 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 withstand high pressure when it work. · Module design, arbitrary combination, which can meet the demand of large water consumption.Specifications: manifold (interior): red copper manifold (exterior): aluminum alloy Glass tube dimensions: 58mm x 1.8m / 47mm x 1.5m Heat preservation: 72 hrs Hail resistance: 25mm max pressure: 6 bar Coating of vacuum tube: SS-C/CU heat pipe : anti-freezing > -35 degree
