Metal-Glass Direct Flow Tube For Solar Collector

1.Perfect reliability
2.Long services-life, over 20 years
3.5-second start-up
4.Easy installation
5.High heat efficiency
Features:
DF70 Metal-Glass Direct Flow Tube has higher efficiency than ordinary heat pipe tube. The absorber makes direct heat exchange with the fluid medium flowing inside, as a result it can have faster heating efficiency, less heat loss and longer service life.
The collector is pressurized, which enables its free-style installation.
Recommended installation angle: 0°~90°.
