Detailed Selling Lead Description
Features:
1) Working principle of low pressure solar heater: adopts the alternative absorption coating to absorb the solar energy, heat the water in the vacuum tube directly, through the cold hot water convection, changes the solar energy into heat energy to store in the water tank
a) Adopts the double-deck highly special hard glass tube of boron silicon
b) Double-deck glass coaxial structure, intermediate layer releases the vacuum, maintain, 5X10-2 Pa high vacuum for a long time while in charge offing
c) Magnetism accuse of alternative absorption coating, AL/N/AL of sputter aluminum nitrogen aluminum alternative absorption coating olar radiation absorption rate a≥93%, hot emissivity Β≤6%
d) Long performance life: 15 years
e) Endures climate feature: thermal efficiency is good in the whole year, can resist diameter 25mm hail |
