raw materials copper heat u pipe solar collector

Technical data:

Working principle:

In evacuated tubes, there is copper pipe folded into a U-shape with aluminum thermal conductors to transfer the solar energy from the inside wall of the evacuated tubes to the circulation fluid in it. Then the circulation fluid take the heat energy into collectors manifold.

Bontel Advantages:1.Evacuated tubes with triple layer selective absorber coating, vacuum degree≥5.2x10-4Pa, absorbing efficiency≥92.5%;2.Applied advanced leaking test technology to ensure the whole system working stably and reliably;3.With effective heat energy transferring Aluminum fins, U pipe collectors get higher temperature in short time;4.High and constant pressure polyurethane foaming technology ensure the outstanding insulation quality;5.Optimal and innovative design make collectors integrated into different buildings;6.Circulation fluid in closed copper pipes(U Pipe), no water in vacuum tubes. There is no corrosion, no leaking , no scaling, no occasional tube breakages in collectors;7.Working life ≥20 years.
