Our sun energy water heating system is widely used around the world.
The key component of sun energy water heating system is high-tech vacuum glass tubes that absorb not only direct sunlight (direct sunlight) but also heat from the environment and when it is cloudy (diffuse sunlight).
External tube made of high resistance borosilicate capable of resisting the impact of hail of up to 2.2 cm in diameter.
The inner tube coated with aluminum nitrate that has excellent absorption of solar radiation.
They are designed to work without problems in freezing zones up to 25º below zero
The use of diffused light allows temperatures above 35º C to be achieved on totally cloudy days.
The curvature of the glass tube (30 to 40 mm in diameter) offers greater resistance to impacts than flat collectors. It is reported to have passed hail equivalent tests of up to 25 mm.
