3m Solar Collector Tube

The 3m solar collector tube refers to a solar collector tube with a length of 3 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.

Working Principle Graph for Parabolic Heating Collector

How to use thermal metal-glass tubes:

1.Solar heating in winter

Matching 2.55mx6m parabolic heating collector generates high temperature water(60-100℃ or 100-150℃(pressed).

This technology is mainly used winter heating for villages away from cities

2. Solutions for high temperature steam(120-180℃)

Replace traditional coal-fired boilers and electric boilers to reduce emissions of dioxide. Widely used in printing and dyeing, food, plywood and other industries that require high-temperature steam. Currently, several sample projects have been completed in Shanxi.
