 Description:

1 Solar vacuum tube solar water heater vacuum tube is the core component , the cover glass and the composition of glass .

2 Glass tube coated on the inner solar selective absorbing film , one end of a spring inside of the card in the cover glass , the other end and the cover glass sealing .

3 The cover glass and laminated within the glass tube under vacuum at high temperature state , the vacuum insulation laminated play a role .

4 Unique stainless steel heat absorbing layer of aluminum nitride , high temperature up to 500 °C, the film does not fall off , not ultra- pure copper cold launch anti- aging mirror , low reflection , heat loss.

5 Cold environment, the collector is good, still have hot water warming faster than the 92% of high absorption , reflectance approaching 6% , the thermal efficiency increased by 12 %, higher water temperatures , more hot water .
