All-glass Evacuated Tubule Collector with U Metal Tubes is a new product for forced
circulation system. It integrates the all-glass evacuated tubes, U metal tubes, copper fin
and the frame, This collector is separate from the storage tank. The selective coating in the inner cover of the evacuated tubes ensures high
energy absorption and low heat radiance losses, which convert solar energy into heat
energy and transfer to U metal tubes by fins. The medium (water or anti-freezing liquid)
in the metal tube has been heated up, and conduct the heat energy to the water inside the
storage tank through plate heat exchanger. The controlling system can control also the
condition of heat exchanging between collector loop and the water in the storage tank.
The evacuated tube collector with U metal tubes can be quasi-tracking in four seasons, the
collector will be in operation as long as sun shines. This collector can be in service all
year round even in cold climate areas in combination with the fossil fuel or electricity.
Advantages
- Highly efficient absorber of high performance with daily average
efficiency over 50%.
- Operation pressure of 6 bar Maximum 20Bar ,can be connected directly with city water
pipe.
- No water inside the evacuated tubes; the solar water heater can still in service even
with several tubes breakage.
- Highly efficient insulation with polyurethane foam.
- Simple structure, easy to assembly and install, diffuse flat plate reflector can be
assembled easily with its module structure.
- Can be used all year round in the cold climate.
- Can be used together with Auxiliary electric boost.
- Automatically controlled.
- Large-scale solar hot water system can be installed either with parallel or series
connections.
