Product Description

Solar Glass Vacuum Tube (LQ-HT-M056)

Super advantage:
1) Select high high-borosilicate glass 3.3 as raw material, high strength, good toughness, and can resist 25mm diameter of hail hit.

2) Thermostatic dust-free three target coating process, absorb more energy absorption spectrum of short-wave light with a wider, collection hot efficient, thermal conductive rapidly, Set than ordinary vacuum tube high thermal efficiency 20%. Low temperature environment quick start, potent collection hot, Cold, low temperature, also have hot water...

3) Resistant to 200 degrees heat, anti-aging, performance not attenuation, and long service life.

Features:

1) High heat effectiveness: Higher than all glass evacuated solar collector tube by 15%

2) Heat pipes conduction: Successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand

3) Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season

4) Low thermal capacity makes the tube start up quickly

5) Energy output within only 2 minutes of sunshine

6) Insulation temperature can reach 250deg; C, average heat efficiency can still be more than 50%; Even under -50deg; C

7) High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube has higher heat output in cloudy weather and in moist areas, especially in winter

8) Solar collecting plate is sealed inside a high quality borosilicate glass tube with 5 x 10 - 3Pa of vacuum, to stop corrosion; Even in moist conditions

Metal-glass evacuated solar collector tube consists of a single glass tube and a flat or curved aluminum plate inside attached to a copper heat pipe.
