*Features:
A) A perfect combination of the vacuum tube and the heat pipe.
B) Higher heating efficiency, advanced heat transferring mode of the heat pipe, excellent selective absorptive coating and perfect heat preservation.
C) Wide application range. Started up quickly even in cloudy days to collect heat effectively. As there is no water in the vacuum tube, it can effectively prevent the decreasing of heating efficiency due to frozen cracking or scaling. It can work normally
even at the temperature of -30 °C.
D) Independent tube makes the system reliable. As each individual tube can work independently, and the whole machine can still work if some of the tubes are damaged.
E) Service life: more than 15 years.
F) The unique connection between the heat pipe and the vacuum tube ensures sealing effect.
G) The replacing of damaged vacuum tube is very easy.
