Description :
Vacuum tube：
￠58×1600mm×18
Each evacuated tube consists of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 25mm in diameter. The inner tube is also made of borosilicate glass, but coated with a special selective coating, which features excellent solar heat absorption and minimal heat reflection properties.
Supports:
(1) Supporters are made of High strength galvanized sheet,
(2) Electrostatic pensu processing, so it is better anti-corrosive;
Insulation:
(1) Use imported high-quality polyurethane foaming material as heat insulating layer.
(2) Use automatic foaming technique with control of quota at constant temperature and high pressure, and it becomes fully spongy after high temperature ripening to ensure the full uniformity of the foam, low coefficient of heat transmission and low temperature change overnight are all controlled automatically by the computers.
(3)The utilization of the density inspection equipment makes sure that the density of the foam layer at gold density， and the blind hole rate above 93% to ensure the lowest heat transmission coefficient and the best heat preservation performance.
Out\Inner tank:
Import SUS304 stainless steel with high chrome, high nickel and great anticorrosion
Argon arc welding techniques ensure the standard wilding line
