Super Conduction Vacuum Tube

Evacuated Tube
Super conductive vacuum tube

Model: JVS
Just like an automobile engine,the computer CPU,Super Conductive Vacuum Tube is the core component of the solar water heater. Its performance lies on the actual film coating technology. JINYI Company adopted a new graded coating technology of Qinghua University,and tube raise the heat. Super conductive vacuum tube are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Super conductive vacuum tube have already been used for years in Germany, Australia, France, Japan Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Jinyi collectors use the most common "twin-glass tube". This type of tube is chosen for its reliability, performance and low manufacturing cost.

Advantage:
One-way heat transfer, 10% higher heat efficiency than the normal vacuum tube.
No water in tube, no scaling in tube, keep tube absorb efficiency.
Can be used in extremely cold area, no frozen risk.
Even if one tube broken, the whole system will still working well.
More humanity performance, can feed water at any time.
