Product Description

2016 High Quality Vacuum Glass Tube for Solar Water Heater
Vacuum tube for solar water heater description
The evacuated tube is the key component to all the thermal heaters and systems. It's similar to a
conventional Dewar flask and consists of two borosilicate glass tubes, resistant 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 convection.
The key element determines function of tube is the technology of the film coating, with the highest absorptance rate of near 97% with common rate of 94% and lowest
emission rate near 3% with common rate of 5%. At this efficiency, it has been very hard to improve the
function any more, even very little part.

Vacuum tube for solar water heater advantage

1. Higher efficiency collector, much lower heat loss with vacuum insulation;
 
2. High pressure and super anti-freezing performance in cold weather condition;
 
3. Less heat loss for closed loop circulation;

4. No system drainage even though one or several tubes are broken;
 
5. No risk of tube breaking from thermal shock;

6. More convenient in system parts carring and installation.
