Advantages of Four-cavity Evacuated Glass Tube

  • The spring holder does not touch the outer tube and the heat transmission through the spring holder is cut off. Its workability is upgraded by 30-35%.
  • Water temperature rises much faster. As there is an Interior tube inside, the water in the Four-cavity EGT is 1/5-1/4 less than that in the normal EGT and can be heated up faster. So there is a faster exchange of the cold water and the hot water, producing more hot water.
  • The neck of the EGT is narrowed at the open end. Tubes in the manifold are closer to each other. More solar energy is absorbed.
