Solar Vacuum Tube

KESUN provides solar vacuum tube also called as solar evacuated tubes. These are perfect for your solar hot water heater assembly and home improvement applications.

The solar vacuum tube is one of the important solar water heater accessories. It helps in keeping hot water overnight. Easier to install on different types of solar water-heating systems. They are proven efficient due to incredible thermos-like properties.

KESUN utilize a 3-layer process that results in coatings; copper, aluminum, and steel. When these are applied on the tubes, it can absorb more solar energy. At the same time, capable to resist up to 300 degrees temperatures.

If you have solar water heating projects, choose KESUN to supply your custom vacuum tube requirements.

The inner design is composed of specially coated layers. These layers helps absorbs the solar energy effectively. Results to heat the anti-freezing water quickly.

  • Length: around 500mm
  • Outside diameter: around 58mm
  • Inside diameter: around 43mm
  • Double wall design with vacuum in between
  • Super-absorbent coating for inner design
  • Simple installation -The tubes are installed after the frame. No hoist or crane is required.
  • If tube leaks, the whole system still works. They are easily replaceable.
  • Guarantee no heat loose caused by vacuum. This means, they still work great in cold temperatures.
  • They are perpendicular to the sun. Therefore, they easily collect sun energy.
  • U Pipe Solar Collector
  • Solar Water Heater Valve
  • Non Pressure Solar Water Heater

Specifications & Applications

KESUN vacuum tubes offer average lifespan of 10-20 years.

The following are the stage processes of working solar vacuum tubes. And an overview of some components’ functions.

Heat then creates streams and shifts to a bulb. The bulb inside is located on the heat exchanger. It is where the pressure and temperature loss. Moreover, this cycle is continuous and lasts for many years.

Evacuated tube solar collector is an important part of solar hot water system. You can find it in resident hot water system or commercial hot water system. Evacuated tube solar collector consist of solar vacuum tube,heat pipe, support frame and manifold of collector.

There are many different shape of manifold box for Evacuated tube solar collector in the market. But you can get all type from Kesun solar. If you are not in very cold area, you can choose standard, standard 2 and round type as you like. If it is very cold area, the big size manifold box is recommended. It has bigger rockwool insulation inside.

Kesun Evacuated tube solar collector is solar keymark certified product. Kesun strictly followed ISO9001 quality management production. And we send our solar collectors for testing according to EN12975 standard.

  • Commercial Solar Water Heater
  • The absorption of solar energy is by selective coating on tubes.
  • Through the aluminum fin, energy then transfers after
  • A heat pipe in the center receives it.
  • Inside the line, a liquid boils at 86 F. They are responsible for heating water.
