Equipment & Technologies
Hard efforts
Using the known as "glass" with 3.3 special
hardware Pyrex glass as raw material, great
strength.
Automatic cutting Round production lines with
high precision.
Deep inner strength
Deionizer and reverse osmosis water treatment
equipment, cleaned by pure water and the inner
tube is cleaner.
Selectively absorbing coating technology, it is
composed with no-dust coating process -- the
bottom reflect ultra pure copper, stainless steel 
nitride aluminum layer and reduce anti-layer. It has
high absorption.
Strict exhaust processes: It has high vacuum and
more durable, without considering the economic
benefits
True skill
High Temperature of 500
the film is not falling,
not aging.
Anti-cold, low reflection, a small heat loss, good
collector results in cold environment, and still have
hot water.
Efficient absorption: high absorption is 92%,
reflection reduces 65%, heat increases 12%. higher
temperature, more hot water.
High vacuum, and can last long. The performance
will not reduce for a long time, and the life
expectancy is up to 15 years.
As long as we make deep efforts, the crowbar could grind into needle.
All-glass Evacuated Solar Collector Tube
All Glass evacuated solar collector tubes are the key component of the Solar Collectors. Each
evacuated tube consists of two glass tubes. The outer tube is made of extremely strong transparent
borosilicate glass that is able to resist impact from hail up to 25mm in diameter. The inner tube is also
made of borosilicate glass, but coated with a special selective coating, which features excellent solar heat absorption and minimal heat reflection properties. The air is withdrawn (evacuated) from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss.
Unlike other types of solar collectors, evacuated tube solar collectors still provide excellent results on
cloudy days. This is because the tubes are able to absorb the energy from infrared rays, which can pass through clouds. Wind and low temperatures also have less of an effect on the function of evacuated tubes when compared to flat plate solar collectors due to the insulating properties of the vacuum.

Three-target vacuum tube
Solar Collector Inc. adopted a new graded coating technology of Qinghua University, and the three-target
vacuum tube raise the heat by more than 12%.
High temperature: by special stainless steel aluminum nitride layer,
it could bear the high temperature of 500
,and the film is not falling, not aging.
Anti-cold: Super-copper launches mirror, Low reflectance, Small heat loss, good collector results in
cold environment, and has hot water.
Efficient absorption: high absorption is 92%, reflection reduces 65%, heat increases 12%. Higher
temperature, more hot water.


Heat Pipe Vacuum Tube
Heat pipe
1.Structure of heat pipe:
Solar Collector Inc. inorganic superconductivity heat tubes are composed of diameter altered tubes and
high efficient collecting tubes. The diameter altered tubes are made of absorption copper pipes of
different diameters. They are used together with top quality “Blue E rhythmus” evacuated tubes so as to the increasing of the absorption efficiency and advantage such as no pipe cracks, long duration.

Advantages:
1) High efficiency and low heat loss
- Compared to common collector, the efficiency can get to more than 40%. Daily efficiency gets to 60%
- Vacuum inside the collector can reach 1.0*10- 3Pa. It is a reasonable temperature to keep warm. Its
one-way conducting technology has been praised the patent of the world. At the time of cloudy days and at night there is no heat loss caused by back flowing through vacuum tube
2) No bomb and split, no dirt
- The working environment is between -60
and 380
. No crash no burst. The patent technology works very well
- The tubes are separated from the water, and the heat conducting components has good performance to bear low temperature. Operation pressure is low, so there is no problem when there is no water in water tank
- Separated from the water, there is no dirt inside the collector. So we do not need to clean it after using
- Starting temperature is low (-60
can start), heat conducting is fast (conduct heat pace: 6m/s),
Because of small volume the heat conduct very fast to the water tank
- The whole collector can bear press to 1.0 MPA, can connect with urban running water system directly
and run automatically
3) High stabilization and long duration
- The seal of this system is reliable, the water tank and the heat transfer box have used the mechanical
seal, so it cannot divulge
- Even if few glass tubes damages, the single or the project system cannot fall into the paralysis
condition because of the massive water leakages. The collector can still run
- The patent medium inside the cooper pipes has good compatibility with the commonly used metal
material, so it does not produce the non-condensable gas; it can sustainable work for 15 years without
any attenuation, duration time can be 15 years.
