Evacuated Glass-Metal Sealed Heat Pipe

Evacuated Glass-Metal Sealed Heat Pipe
Product Detailed
1.Glass-metal heat pipe; 2.70 and 102mm diameter available; 3.Copper strip; 4. 2.8mm thick glass tube.

CIB Solar's Glass-metal sealed evacuated heat pipe are suitable for OEM manufacturers and can be used for various kinds of installations. Absorber and heat pipe are mounted in a highly stable borosilicate vacuum glass tube. This prevents damage and the heat loss that occurs in conventional solar collectors. The absorber is sputtered with solar selective coating to ensure high absorption and highest efficiencies even on cloudy days.

Features
