Technical Data
This solar collector adopts the alternative absorption coating to absorb the solar energy, heat the water in the vacuum tube directly, through the cold hot water convection, changes the solar energy into heat energy to store in the water tank. The water flow inside the solar tube and was heated inside tube then rise back to the manifold box naturally. Single wing or double-wings as you like. It's widely used for commercial heating like hotel, school, hospital, swimming pool etc. Solar Collector Module of 20 tubes, 25 tubes, 30 tubes, 40 tubes, 50 tubes, 60 tubes are available.
