Detailed Product Description

solar vacuum tube

Sizes:
47*1500mm
47*1800mm
58*1500mm
58*1800mm
Coating Colour:black or blue

Kingeagle vacuum tube adopt dry absorb type selective coating with lower remittance,is solved the probles of normal tube having not good curve of emittance,when the temperature higher,the remittance higher,which reduce the efficiency of the tube.
Three Higher Points of this new tube:
1,Higher efficiency:The absorbance increased by 14% with remittance reduce by 30-40%
2,Higher heat conduction:dry exposure temperature up to 270 C and can endure -30 C environment temperature and still working
3,Higher vacuum degree:unique technoloty to keep the vacuum degree,stable absorbance which grarantee the long life of the tube

Customized is OK
