Product Description

Just like an automobile engine, the computer CPU, evacuated tube is core of the solar water heater.

It`s similar to a conventional Dewar flask and consists of two borosilicate glass tubes, resisting to high chemical and thermal shock. The outer side of the inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to avoid heat loss in conduction and conversion.

The key element determine that the performance of tube is the technology of the film coating, and it is the best efficient tube you can find in China, with the highest absorption rate of near 93% comparing with common rate of 90% and lowest emission rate about 6% comparing with common rate of 7%.

Three-target solar vacuum tube
- Key component of solar collector and solar water heater
