1.High temperature resistance. 2.Better anti-high coldness. 3.15 years experience. 4.suitable for solar heating equipment.

Make use of the international advanced three targets high temperature coating technology to form a fast hot core, the heat absorbing rate is increased by 18% more than the steel target tube.

1. High temperature resistance, anti-high cold, keep the heat lasting long time. The purple golden tube can provide the operating temperature up to 500 °C, which is not easy to  bombing to avoid the film aging, loss ,color changing, caused by long-term exposure,  and other issues, and make increasing the significantly using life.

2.Better anti-high coldness, even can be working under -- 40 °C
