Solar vacuum tube specificationsI would like to know its specifications, but do not know how to see, who can teach me under the 'thank you!
1 Classification: (1) the use of solar water heater solar vacuum tube in accordance with the pipe diameter is divided into 37, 47, 58, 70mm, etc., according to the length is divided into 1.2, 1.5, 1.6, 1.8, 2.3m. More commonly used is the 47*1500 vacuum tube.2, solar vacuum tube Description: the product to adapt to a wide range of solar energy is the first choice of products.Length: 1.2 m 1.5 m 1.8 m 2 mExternal diameter: 47mm / 58mm /70mmGlass thickness: 1.6mmMaterial: high borosilicate 3.3Absorption layer: aluminum nitrogenAbsorption rate: >92%Emitting aluminum: <8%Vacuum <5*10-2PaStuffy temperature: >200oCService life: more than 15 yearsPacking: 20 / box
The main specifications of solar vacuum tube.Three kinds of vacuum tube diameter:47, 58, 70, which refers to the outside diameter.To say the endothermic effect is good, also answer 70 pipe, tube heat absorption area larger is larger, the endothermic effect is better, the double pipe insulation effect is also very good.
Vacuum tube specifications?Is nothing more than the length, diameter, diameter diameter, coating, glass tube thickness, if the technical personnel, the need to download a look at Lou GB
