Product Description

Specifications

Vacuum tube is an integral part of solar collector. Vacuum tube is the same as the traditional Dewar (vacuum) bottle.

Vacuum tube is an integral part of solar collector. Vacuum tube is the same as the traditional Dewar (vacuum) bottle.it contains two borosilicate glass tubes. Outer layer of the inner tube coated with solar selective coatings. One end of inner tube connected with the outer tube, the other end sealed with the outer tube. Between Inner tube and outer tube of the annular space is vacuum mode,through the conduction and convection to reduce the heat loss.

Features:
energy transform efficiency, low heat loss
the stability of advanced coatings, up to 380 centidegree.
15-year warranty period
a high degree of vacuum in a cold climate to ensure the normal operation.
