Solar collector tube introduction
Feature:
1 Quality warranty :15 years
2. Quickly thermal collecting efficiency.
3. It works fine under cold weather and area.
Three kind of solar collector:
1.Common :evacuated collector tubes.
2. High-efficiency: Three-target evacuated collector tubes: blue and black-golden
3. High-efficiency: Three-target evacuated collector tubes: purple-golden (purple and golden)

Start up fast and collect solar energy fully
Unique super pure copper surface,allowing lower reflection and minimal heat loss.
High level vacuum ensure operation under cold weather.
Long time warranty to 15 years
Our solar collector can start up fast and collects solar energy fully, there is no need to wait and the hot water is available immediately, high level vacuum ensure operation under cold weather, and the unique super copper surface allowing lower reflection and minimal heat loss, the current products mainly include: diameter: 47/58mm, and the length is 1800mm, but we can also provide products as your request. Long time warranty for 15 years.
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 under- 30 ºC. high temperature special efficiency tube, because the membrane layer stainless steel ion high temperature resistant, fight air drying. Membrane layer under the condition of the 400 ºC, not attenuation, not aging, discoloration.
