Working principle:
1) Many-tubes-connected makes the solar collector system
2) The project is composed of solar collector, water storage tank, auxiliary heating system, computerized controller, pipe cycling system and other relative system
3) It uses the vacuum tube for heat transferring. When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically and take the heat to the water tank
5) In case the temperature of the water tank does not reach the set temperature such as in cloudy or rainy days, the water system will start the auxiliary heating device automatically

Features:
1) ISO9001 / CCC / CE certificate
2) Super and strong heat absorption & preservation
3) Without incrusting, long usage life
4) According to the required configuration, it can be divided into two types, one is vertical and the other is horizontal
5) Large water capacity
6) It's widely installed in hotels, hospitals, schools, collective dormitory, public bathrooms, armies etc.
