Start up fast and collect solar energy fully
Unique super pure copper surface,allowing reflection and minimal heat loss.
High level vacuum ensure operation under cold weather.
Long time warranty to 15 years
Our vacuum collectors tube can start up fast and collects solar energy fully, there is no need to wait and the 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.
