· The pipeline is made of all the red copper and conducted by heat transfer medium liquid. Water can't 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.
