Evacuated tubes,China Solar Water Heater Distributor
Evacuated tubes have been developed particularly for northern climates where outdoor air temperatures are low.The evacuated tubes are made in high quality boron silicon glass.It can endure 0,6MPa pressure and the hail which is smaller than 25mm.The absorption is boosted by a Nitrogen and Aluminum solution sputtered in the space between the two pipes. The rate of absorbing is more than 0,92.The tubes exist in two different diameters: Φ47mm-1500mm and Φ58mm-1800mm .The rate of vacuum between the pipes is below 5*10-3Pa which is the best rate currently available for evacuated tubes. The average pressure in the market is 5*10-2Pa.
