Solar vacuum tubes

 

Trifire vacuum tubes are coated by three layers in the inner tube. One lay is reflection reduction layer, one is absorption layer and the third layer is infrared layer.Trifire tubes  is produced with three layer porcelain new technology of stainless steel, red copper and aluminum nitride with the sputtering controlled by a three butts magnet. Trifire tubes can quickly absorb heat, and its heat preservation ability is quite good.
