Three-target tube performance lies on the coating technology, The three-target evacuated tube rise the heat more than 12%
1) High temperature: by special interference-layer it could bear the high temperature reach to 300℃, and the coating will not shed and aging.
2) Super anti-cold: Super-copper launches mirror, low reflectance, little heat loss ,good absorber results in cold environment, also can generate hot water.
3) Efficient absorption: High absorption is 92%, reflection reduces 65% heat increases 12% Higher temperature, more hot water.
