The 4m solar collector tube refers to a solar collector tube with a length of 4 meters. This type of collector tube is likely used in solar thermal systems or solar water heaters to absorb sunlight and convert it into heat energy. The specifics of its design and application may vary based on the intended use within a solar energy system.

Manufacturing process:
Working Principle Graph for Parabolic Heating Collector
How to use thermal metal-glass tubes:
Matching 5.77m opening parabolic heating collector, mainly used for CSP projects With 4060*70*125 tube
The system includes a series of core equipment such as parabolic heating collector, molten salt energy storage system, tracking system, control system, steam generator, steam turbine unit, etc
The 4060 125 70 heat collector tube produced by the company is the core component of the heat collector, with a temperature resistance of over 500 ℃. It uses molten salt or heat transfer oil as the working medium, and the molten salt tube serves as an energy storage device, with a 24-hour power generation capacity. This technology is currently in the demonstration and promotion stage in China, and it requires the cooperation of professional design institutes, construction teams, and equipment manufacturers to better complete it. Currently, our company only provides heat collecting tubes.
