color steel solar water heater:

Future:

heat preservation 72-80h

good freez protection,it can stil work -25°C

vacuum tube:

Vacuum  tube assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass , gradual chance of ALN-SS-C/CU selective complex absorptive coating, and these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo , with its temperature up to 380 °C.

Specification of evacuated tube :

♦Lass material : borosilicate glass 3.3

♦Absorptance : α=0.92~0.96 (AM1.5)

♦Emittance : ε=0.04~0.06 (80°C±5°C)

♦Stagnation temperature (temperature inside of empty evacuated tubes) : 220~260 °C

♦Average heat loss :ULT 0.6~0.7 W/(m2*°C)

♦Hail resistance :< ø25 mm

♦pressure—endure: 1Mpa
