Advantages of Four-cavity Evacuated Glass Tube

 

1.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%.

2. The diameter of the EGT is narrowed down at the open end. Two neighbourtubes are much closer to each other. So the aperture area is enlarged and more solar energy can be absorbed

3.. 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.

 

This is a very new type of evacuated glass tube,few company can make it. If you are interested,please don’t hesitate to contact.
