Feature：
● Apply for two layers 3.3 high boron silicon glass tube
● The two layers glass tube , with same axis is vacuum zed between them , the vacuum degree can reach
P ﹤5x10-2 Pa
● Coated with Al/N/Al selective absorbing coating material .
● High absorbing sufficiency : the vacuum magnetic-control sputtering selective absorptive coating on the heat-collecting plates has a high absorption coefficient of more than 94%, and the emission coefficientaround 6% .
● Long life :the life span can reach to 15 years .
● High practicability : able to endure impact of hail less than 25mm in diameter with high heat effeciency throughout the year .
