Structure and Principle: The heat pipe is hollow with the space inside evacuated, much the same as the solar tube. Freeze Protection: Because the heat pipe is located within the evacuated glass tube, brief overnight temperatures as low as -20oC (14oF) will not cause the heat pipe to freeze. ⊙ High heat conduction coefficient:is 2000-5000 times of matal materials. ⊙ High quantity of heat conduction:is 1000times od metal materials. ⊙ Low temperature difference:less than 4℃ difference in 2 meter long pip ◆ Specifications: Manifold casing material | Aluminum | Frame material | Aluminum | Header pipe material | 1.2mm thickness Copper | Heat pipe material | 0.7mm thickness Copper | Insulation | Polyurethane 55mm or Rock wool | Rubber seals and rings | UV stabilized high temperature silicon rubber | Test pressure | 9 bar | Collector mounting | Flat roof/inclined roof | Mounting angle | 15℃-50℃ | Inlet Outlet | 3/4” |

Features: * Reliable, efficient, twin-glass solar tubes heat pipe * Copper heat pipes for rapid heat transfer - Low maintenance effort - Easy installation of single or multiple units * Corrosion resistant silver brazed copper header NOTE:Absorber area is the part of the collector that actively absorbs the light rays. For solar tubes this is defined as the cross-sectional area of the inner tube (selective coated) measured using the outside diameter. (Eg. 0.047 x 1.72m = 0.08m2) |
