Three Target Solar Vacuum Tube
Feature:
Using high borosilicate 3.3 glass, the thickness and diameter of the raw material reach the national standard.The time of sputtering plating is up to 45 mimutes, the retia is at least 12 layers.Advanced vacuumizing craftwork, strictly exhausting under 450 centigrade temerature of 60 minutes, the vacuum tube can be 5*10-4 Pa.High absorptivity and low emittance.Inteference film technology replaces traditional gradual-changed film technology.The gradual-changed film is a low retia adopted by many manufacturers so far.But the inteference film is a best vacuum tube coating which has the newest plating technology and the best effect of absorptance sun energy in the current world.Having three "highs".they are high temperature resistance,high cold resistance and high heat efficiency(contrast to the single target vacuum tube ,its absorptivity has improved 5%~7%)In the event of same capacity and sunshine,it can output more and hotter water than single target vacuum tube.The coating won't fall down,not run,not aging,don't be afraid of idle sunshine,antidecrease.Also it can resist super cold,product hot water normally under -30 centigrade.Technical Parameter:
