Product Description

Factory Direct Selling 100mm High Diameter Solar Evacuated Tube

100mm evacuated tube description

The evacuated tube is the key component to all the thermal heaters and systems. It's similar to aconventional 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.

100mm evacuated tube technical datasheet

100mm evacuated tube 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.
