solar energy(Certification ISO:9001:2000) vacuum tube

solar energy,solar collector tube our goods are the ideal utilization of solar energy products and receive the great acclaim of

  solar energy

Technical characteristic: the entire glass vacuum collection heat pipe uses endures cold the thermal shock, the anti-hail's double building store height boroscilicate glass, the band perfect vacuum, the inner layer glass outer wall uses magnetism to control sputtering vacuum coating labor The skill, plates has the international advanced level selective absorption coating, has the extremely high absorption rate to the sunlight and the extremely low thermal emissivity, the service life may amount to above 15 years. List Tube experiment: About the cloudless day 18 two hours below zero, the vacuum tube domestic waters may reach the boiling point. The specification has φ47/1000mm, 1200mm, 1500mm, 1600mm, also to be possible according to The user need has custom-made each kind of specification product. Is the solar-powered water heater factory ideal core necessary part. Through IS09002 international quality system authentication. Technical parameter: Structure: The glass double-decked coaxial structure (band pulls out vacuum) Glass materials: Boron silicon 3.3 glass; The performance conforms to ISO3585:1991 Outside caliber and thickness: 47±0.7, δ=1.6±0.1 In caliber and thickness: 37±0.7, δ=1.6±0.1 Manages the length: 1200±5mm; 1500±5mm; 1600±5mm Heat-resisting impact: Can withstand 25 below cold water with 90 above the hot water to attack repeatedly alternately 3 times, but does not damage Pressure resistance: 0.6MPa Anti-hail: The withstanding radial direction size is not bigger than the 25mm hail attack
