A perfect combination of the vacuum tube and the heat pipe.
1).higher heating efficiency:
Heat transferring can be started quickly even under cloudy day. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heating efficiency due to frost cracking or scaling;
2). Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15 years;
3). The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube;
Starts up fast and collects solar energy fully;
Unique super pure copper surface, allowing lower reflection and minimal heat loss;
High level vacuum ensure operation under cold weather;
Long time warranty to 15 years;
Looking forward to having business with you in the near future;
Advantages of heat pipe solar collector
Comparing with vacuum tube solar collector
1. High efficient heat pipe tubes;
2. High pressure and anti-freezing collector;
3. Less heat loss for closed loop circulation;
4. No risk of tube breaking from thermal shock;
5. No risky of tube breaking from water freezing;
6. No system drainage even though one or several tubes are broken;
Comparing with flat panel solar collector.
1. Higher efficiency collector, much lower heat loss with vacuum insulation;
2. Super anti-freezing performance for heat pipes in cold weather condition;
3. No system drainage even though one or several tubes are broken;
4. More convenient in system parts carrying and installation;
