Product Specifications
Product Description
1. Firm selective coating
The surface of the tubes is completely rinsed by the water removed ion so that the selective coating can be adhered to the tubes firmly. It guarantees the efficiency and service life of the collector tubes.
2. Perfect process technology
The patented technologies in circular sealing and annealing system make a solid linkage between the inner and outer tube and fully eliminate the internal stress, solving the problems of liable damage in the sealing parts.
3. Fantastic technical data
Advanced skills in coating and efficient system in evacuating provide the absorption of selective coating α≥94.5% and the emission ≤5.5%, which greatly improved the performance of the collector tubes.
4. Wide usage
The vacuum evacuated collector tubes can be applied not only in the water heater under various weather conditions, but also in the hi-tech areas such as refrigeration and generating electricity.
Length 1500mm 1800mm
diameter 47mm 58mm
Material Borosilicate glass 3.3
