Standard: ISO CCC CE

The perfect combination of the vacuum tube and the heat pipe.
1) high heat efficiency: Advanced heat transfering style of the heat pipe, excellent selective absorptive coating and perfect combination with high vacuum heat preservation.
2) wide applicable range
As the heat pipe has less heat capacity, it can be started quickly even under cloudy day and collect heat effectively. It can work normally even minus 30 degrees, as no water in the tube, it can effectively prevent lowing of heat efficiency due to frost cracking.
3) Each individual tube can work independently, and the whole machine can still work if any single tube was broken. And the service life of the heat pipe can be over 15 years.
4) The unique connection between the heat pipe and the vacuum tube can ensure both sealing and glass vacuum tube avoid damage.
