MGV heat pipe tube pressure solar collector
φ70mm MGV Heat Pipe Tube is one of the core technologies of JIADELE , it’s more suitable for middle temperature applications. It has a bigger absorber area with characteristics of strong resistance of very low temperature, better thermal performance, higher operating temperature and wide range of applications.
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 (-50°C)
7. High vacuum grade (10-8 bar) guarantees high efficiency even in cloudy day, cold environment and high-temperature application
