1 Features of All Glass Heat Sensitive Coating Evacuated Solar Tube
Strong Glass
The tubes are made from a type of glass called Borosilicate, the same base material as used in many Pyrex glass products used in kitchens around the world. Borosilicate glass has the
characteristic of being very strong and also has excellent light transparency (>94% ) .
The wall thickness of the glass greatly impacts the strength, longevity and naturally also the cost. SANENG vacuum tubes are custom made to strict requirements that exceed the industry
standards, including a 1.6mm thick wall ensuring excellent strength and resilience to hail impact.
To confirm the strength of the tubes, each batch of evacuated tubes assembled in the Sanneng factory have randomly selected samples tested by dropping a 30mm / 1.2" diameter steel ball
onto the tube from various heights.
Vacuum Insulation
The name "evacuated" is used to describe the process that expels the air from within the space
between the tube tubes, forming a vacuum. A vacuum is an excellent insulator against heat loss,
and so evacuated tubes are able to operate very efficiently when there is a big difference between the inside of the tube and the outside ambient air. For this reason vacuum tubes are the ideal
choice for high temperature hot water applications or locations that get cold in the winter.
Barium Getter
In order to help maintain the vacuum over the 15to20 years life of the vacuum tube, a barium
getter "soaks up" any remaining gases in the evacuated chamber plus any fresh gases such as
Nitrogen that can slowly permeate through the glass over time, a process known as outgassing.
This barium layer also provides a clear visual indication of the vacuum status; the silvercolored
barium layer turns white if the vacuum is lost making it easy to identify a fault tube.
Solar Absorber
The absorber coating comprises a base layer of Aluminum on the outside of the inner glass tube
followed by thin layer of the dark colored AL/N material. These coatings are applied using a
method called DC reactive sputtering which is extremely reliable after having been finetuned
over the past 20 years since it was developed, threetarget selective coating with its special
elements and coating method enables high temperature resistance upto 380 °
2 Advantages of All Glass Vacuum Tube Solar Collector
Comparing with flat panel collector
1. Much more economical for solar water heating application;
2. Higher efficiency with much less heat loss in glass tube;
3. Working all year round even in subzero temperatures;
4. Inexpensive tube and easy to maintenance;
5.More convenient in parts carrying and installation;
