Features of All-Glass Vacuum Tube / Glass Tube Fuse

Our All-glass Vacuum Tube is made of dual borosilicate glass tubes, the space between the two tubes is evacuated. The AL/N/AL selective coating on the outer wall of the inner tube absorbs sunshine and transforms it into heat which in turn heats the cold water in the inner tube. When the water in the tube is heated, its density will decrease and will go upward into the tank; Meanwhile the cold water in the tank will flow down into the tube due to its greater density. Thus, the circulation and heat-exchanging in the system is completed. The color of the inner tube is black-grey. This vacuum tube has a high heat-efficiency and low price. It is suitable in areas with winter temperature above below zero 20º C.
