Triple concentric solar collector tube:
Its most distinguished character is the structure--adding a glass tube thinner than diameter of inner tube ,two edges being fixed by a stainless steel cross which remains steady enough. Whih one more tube inside , it has the bilateral heating effectiveness.
In order to reduce energy loss through heat emission, the most efficient absorbers have a selective surface coating, which is rinsed by the water moved ion so that the selective coating can be adhere to the tubes firmly . It guarantees the efficiency and service life of the collector tube.
Its 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 problem of liable damage in sealing parts.
It can be applied not only in the water heater under various weather conditions ,but also in the hi-tech areas such ai refrigeration and generating electricity.
Our solar collector tube stands out not only because of its quite low emission rates, but also because its production is emission-free and energy-efficient.
