Larger-Cabiler Solar Vacuum Tube Diameter 137Mm

Our solar vacuum tubes has prosperity of high absorption and low emission. The vacuum tube consists of outer tube, inner tube, (al-n-ss-cu) coating and holder.Al-nn-ss-cu is coating for three target tube. Three target assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass, and gradual change of al-n-ss-cu selective complex absorptive coating. These make three target vacuum tube have high performance of absorption and low reflection ratio. Because of the coating, three target vacuum tube’s absorption rate increase 30%-50% than normal tube.

Heat pipe vacuum tube
Products detail:
Perfect combination of the vacuum tube and the heat pipe.
1.High heat efficiency: advanced heat transferring style of the heat pipe, excellent sclective absorptive coating and perfect combination with high vacuum heat preservation.
2.Wide applicable ranger: as the heat pipe has less heat capacity, it can be started quickly even under cloudy day and collect heat effectively.It can work normally even -30?, as no water in the vacum tube, it can effectivelyprevent lowing of heat efficiencydue to frost cracking.
3.Each individual tube can work independently, and the whole machine can still work if andy single tube was broken.And the service life of the heat pipe can be over 15 year.
4.The unique connection between the heat pipe and the vacuum tube canensure both sealing and glassvacuum tube avoid damage.
