50 Tubes Powerful Thermal Stainless Steel Manifold Vacuum Tube
Solar Collector for Hopsital
Description
non pressure solar collector evacuated tube , hot water supply with
low cost
Solar Thermal is specialized in making solar vacuum tubes.
Tubes not only have different colors, but also have very stable
film, which leads to a fast heating and an excellent heat
preservation.
Solar vacuum tube assimilate the advanced 12 layers of spattering
deposition of trivalent technology,high borosilicate glass, gradual
change of CU/SS-ALN(H)/SS-ALN(L)/ALN selective complex absorptive
coating.
And these make vacuum tubes have high performance of absorptance
and low reflection ratio.
Through the inter layer,vacuum has a unique effect of thermal ,with
its temperature up to 380°C of idle sunning,performing a strong
heating ability.

How does solar vacuum tube work?
After installation and check the heating collector system
correctly, cold water is filled in the water tank.
Due to gravity, cold water flowed into the vacuum tubes, absorbing
the heat (which the temp. might reach 250 degree centigrade).
Cold water changes into hot water and goes back to the water tank.
Product Advantages :
1. Excellent material: High borosilicate glass 3.3 is adopted as
the raw material.
2. High thermal efficiency: Pure vacuum layer without impurity.
Degree of vacuum is high and lasts long, possessing extremely high
absorption to sunlight with extremely low thermal emissivity.
3. Small thermal losses: Higher degree of vacuum is kept between
vacuum heat collection pipes, reducing thermal losses caused by
heat conduction and heat convection to the maximum.
4. Long life: Performance of film plated layer is stable, being not
easy to aging and attenuation. Processes in links of material
selecting, production, transportation and quality inspection, etc.
are strict with longer service life.
5. Corrosion resistant: Performance against chemical corrosion is
extremely good, appropriate to various kinds of water quality.
6. High degree cold resistant: Even in high latitude in
Northeastern China area with high degree cold temperature bitter
cold, hot water can still be used normally, displaying super high
heat collection rate.
Shock Resistance Test:
Solar vacuum tubes can work in harsh environment. Hot water is
available because of good vacuum tightness in cold weather. And
also the borosilicate glass 3.3 can bear collision in a certain
level. Photos below are a test about this.
