Specifications and Product Details:

Solar vacuum tube:

working principle:

1.thermosiphon solar water heater works in this way:warm water rises when the phenomenon known as natural convection happens and water circulates between the collectors and tank.the tank must be installed above the collector.

2.as water in the collector is heated,it becomes lighter and naturally rises into the tank above.meanwhile,cooler water in the tank flows downwards into the collector,thus causes circulation throughout the system,these systems ard reliable and relatively inexpensive.

material:

1.volume of storage tank:120L,150L,180L,240L,300L

2.non-pressurized water tank:

insulating layer,polyurethane foaming ,thickness:55mm

outer shell of tank,colour steel,thickness:0.4mm

inner tank,stainless steel SUS304-2B,thickness:0.4mm,normal working pressure:0.4bar,

3.dust ring gasket :ABS

4.evacuated tube:three-target tube,high boron and silicon,content 3.3,structure,gradual change SS-AL-Nx/Cu,selective absorption coating

5.frame: galvanized steel plate with plastic spraying 1.4mm thickness

6.controller:SR500

advantages:

1.can be operated completely automatic if connect with intelligent controller.

2.Simple structure,easy plug-in installation,can be installed both in flat and inclined roof,and can be use with an auxiliary electric booster as to provide hot water without sunshine.

3.Superior heat preservation ensured by one-off molding polyurethane foam with thickness 50-55mm,

4.Suitable for campong area,holiday residences.

5.water introduced into vacuum tube

6.long service life,can be used as long as 15 years
