Place of Origin Shandong, China

Brand Name Bomix-glass

Model Number 58*47/1800

Type Vacuum Solar Collector

Application Solar Thermal

Pipe Material Glass

Features: Absorptance of three high efficiency solar vacuum tube increased by 12%, and

launch reduced by 30 to 40 percent, the super absorbing, heat loss less, warming faster.

Efficient tube, the super absorbing, thermal efficiency is high, warming faster, in the same

light conditions, can create more and higher temperature water than common tubes ;

high cold tube, copper ions for the launch of aluminum ion mantua, so low 0.2 thermal

loss rarely, in high cold environment can still work normally. hot water turn out as usual

1.Standard 3.3 high borosilicate glass tube
2.Low coefficient of heat loss
3.Good performance & price
4.15years warranty
