Features:

TM70 Metal-Glass Vacuum Tube has higher efficiency than ordinary heat pipe tube. With characteristic of 30 second heat output and 300 °C condenser stagnation temperature, it can provide more water of higher temperature and have wider applications. “Dry” connection design makes the system workable even though one tube breaks. Excellent insulation enables the collector suitable for any environment all over the world. Recommended installation angle: 15°~90°.
