Specifications and Product Details:

Gold purple solar collector tube is
1)higher absorptance and lower emittence
2)good resistance to cold or hot environment

It is made on the basis of Three merits collector tube . The time of metallic-membrane plating is comparatively longer than others, the chemical compound in the absorption layer keeps very pure,which invariably leads to the high absorption rate.

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
