Advantages


  • Wash process - They never have the chemic wash process. So the inside of heat pipe has impurity that will influence the heat exchange.
  • Structure of the end - The structure of our tube end is special taper, which can resist freezing. Their end of tube is quite different.
  • Welding method:We use silver welding between the top and tube body, so the connection part is argent. As they use normal welding, this part  is black. Silver welding can make sure the top won't leak air after long time thermal impact.
  • Special liquid - The liquid inside of the tube is extremely different, but it's difficult to see. Our liquid is patent products, with high efficiency, without poison to people. It can keep the tube working with high efficiency for 15 years. But usually, their liquid has low efficiency and disappear very quick, usually one year later you will find the tube's efficiency has been reduced a lot!
