Solar Absorber

The solar absorber is a key component that absorbs solar radiation energy into heat energy and transfers heat to water. The choice of material, structure and surface coating of the heat-absorbing core have a decisive influence on the performance of the water heater. The requirement for the heat absorption plate is to have a certain pressure bearing capacity, good compatibility with water, and high thermal performance.

BTE BENEFITS:

1. The laser welding Line developed a small melting pool, it means enhanced the connection strength between absorber and riser pipes, the result is promise longer life of solar absorber

2. The appearance of solar collector without welding line is more beautiful and integrated well with building’s roof

3. The is no destroy of the surface of blue coating film, in the flat plate solar collector

4. The distance between two welding spots is 3mm, more welding spots take high transmission to system
