Detailed Description

Features 1. Perfect reliability 2. Long services-life, over 20 years 3. Low specific heat capacity, fast start up 4. Easy installation, convenient maintenance 5. High heat efficiency, higher than that of normal vacuum tube 6. No water flows inside the tube, anti-scaling, preventing tube from frozen to crack in extreme cold environment (-50oC) 7. High vacuum grade (10-8 bar) guarantees high efficiency even in cloudy day, cold environment and high-temperature application Details TM70 Tube (70mm Super Heat Conduction Metal-Glass Vacuum Tube) This is FULL-VACUUM Tube with Heat-Pipe. The absorber plate catches the sunshine and transfer the heat to the heat-pipe DIRECTLY. Then the heat-pipe transfers the heat to the condenser above, where heat exchange is made with the water in the collector. The system is easy to install. No water flows inside the tube, which makes the system remains workable if one tube breaks.
