The vacuum tube is the key to a water heater, just like the engine to a car. The best collection property and service of a vacuum tube directly impacts the performance of the solar water heater. Therefore, a superb solar water heater needs one-classed vacuum tubes. This product adopts the leading technology in the world. The glass adopts the high born silicon extra-hard glass which has the characteristics of cold and hot resistance, good crush ability, high mechanical strength and good transmittance. The jiadele vacuum heat collection tube is produced with three layer porcelain new technology of stainless steel, red copper and aluminum nitride with sputtering controlled by a here butts magnet. This technology reaches the international advanced stage. The product can quickly absorb the heat and heat preservation is good.
1, unique three-layer absorption technology; 2, unique stainless aluminum absorbtion layer, allowing high temperature endurance and preventing peeling off even when the glass gets waxy degeneration. 3, preventing coating layer against degenerating, color fading or performance degeneration due to exposure the empty vacuum tube under the sun over time; Extending the service life of the product. 4, incorporating three layer interference coating technology; 5, unique super pure copper surface, allowing lower reflection and minimal heat loss; 6, ideal heat collection efficiency in extreme cold weather, with hot water available at a temperature as low as -30 c
