Vacuum tube solar collector is part of a solar water heating system
for swimming pool heating, hotel hot water supply.Evacuated tube
collectors are a slightly more recently developed technology,
introduced to the market in the 1970's. . The glass tube actually
consists of two walls of glass. In between the two walls, all the
air is removed, resulting in a vacuum in the same manner as a
clear Thermos bottle would function. This vacuum is the best
insulation one could ask for, and gives the evacuated tubes a much
better heat retention than air space. Specialty:1. Heating
efficiency is very higher than Flat panel solar collector.2. Quick
operation.3. Strong freezing resistance.4. Easy installation,
convenient maintenance.5. Completely combined with building,
install on wall, roof or ground etc. Technical
specification:1. Outer manifold material: Galvanized steel 0.4mm
thickness2. Inner tank material: Stainless steel 304 2B,
0.41mm thickness3. Insulation material: High Density
Polyurethane foam4. Frame material: Galvanized steel 1.5mm
thickness5. Seal material: Stabilized high temperature silicon6.
