solar collector(U pipe collector)

Standard: Solar Keymark, EN 12975 standard Description: Constitutes: vacuum tube , U pipe cooper ,fins, heat transfer fluid, header, insulation layer Solar Keymark certified U pipe solar collectors include: HUJ-16/21,HUJ-12/21,HUJ-1 6/18,HUJ-12/18,HUJ-16/16,HUJ-12/16 Absorb area:1.522m21.142m2, 1.296m2, 0.972m2, 1.146m2, 0.860m2 Length of the tube: 1.6m,1.8m,2.1m Numbers of the tube: 12pcs, 16pcs Maximum pressure: 1300 kPa Operating pressure: 600 kPa Material of the cover tube: Borosilicate glass Transmission of the cover tube: 90% Outer diameter of the cover tube: 58mm Thickness of the cover tube:1.8mm Distance from tube to tube: 88mm Heat transfer fluid: Water-glycol Material of the fins: Aluminium Thickness of the fins: 0.3mm Material of the header pipe: Copper Number of header pipes: 2 Outer diameter of the header pipe: 15mm Inner diameter of the header pipe: 13mm Material of the insulation in the header: Polyurethane Thickness of the insulation in the header: average 20mm Sealing material: Silicon ruber The characteristics: 1.

The vacuum tubes transform solar light into heat energy and then transfer the heat to the working media depending upon the fin and U-shaped copper pipe in the manner of thermal conduction. 2. There is no water in the vacuum tube,so the tube will not broken in the winter. 3.

It has a smaller thermal loss,stronger adaptability and better performance of aging-resistant membranous layer. 4. Can operate with water pressure up to 0.6MPa 5. Can be combined with existing energy source 6. Storage do not need be installed above the collector 7. It can be combined with the architecture perfectly 8.
