Borosilicate glass Solar Collector Tube

Borosilicate glass Solar Collector Tube
Product Detailed
1 Warm up quickly 2 Highly effective absorption 3 Heat preservation effect is remarkable 4 Life: over 10 years WORKING   PRINCIPLE:1  The  vacuum  tube  is  composed  of  inner  and  outer  glass  pipe,selective absorption layer  and  vacuum  space. 2  The  vacuum  absorbs  the  solar  energy by  absorption  layer  and  turns  it  into  heat  energy.


1 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.
