Export to Europe solar copper heat pipe 58/1800

Features:

A perfect combination of the vacuum tube and the heat pipe

1:higher heat efficiency : advanced heat transferring style of the heat pipe ,excellent selective absorbent 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 fine day and collect heat effectively . it can work normally even the temperature is very low .As no water in the vacuum tube ,it can effectively prevent lowing of heat efficiency due to frost cracking of scaling .

3: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 15years .

4:the unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube .
