Solar Hot Water Collector For Hopsital

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.

Model and Data

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.
