Kingeagle's vacuum tube adopt dry absorb type selective coating with lower remittance, it solved the problem 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 Point 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.[...]
