Characteristics :

• It is completely made of copper good performance under pressure, the black-chrome-plated copper-strip and copper-pipe is welded by ultrasonic welding machine.
• The black-chrome-plated coating has excellent quality with high absorption efficiency and low emissivity.
• The coating is resistant to high temperatures: in general if empty, under temperature of 220C, the performance and quality of collector will not be affected materials and coatings can bear lience weather and have a long life span, endothermic copper-strip with Nickel-plated has excellent resistance to corrode, which can be used more than 15 years.
