2.Three High Evacuated-tube
Advantages:
High temperature:By special stainless steel aluminum nitride layer,
It could bear the high temperature of 500'C,and the film is not falling, not aging.
Anti-cold:Super-copper launches mirror, Low reflectance, Small heat loss, good collector results in cold environment, and has hot water.
Efficient absorption:High absorption is 92%, reflection reduces 65%, heat increases 12%.Higher temperature, more hot water.
