Inner CPC solar collector


Product introduction
 
The Himin inner light-focusing U pipe collector includes a header, vacuum tubes, U pipes, mounting frames and a tube bottom rack. It is typically used to collect heat for space heating or domestic hot water. The collector can be installed solely or connected together.


Features
1.   Use vacuum tube with built-in reflector technology and the heat transfer way through u pipes which can reduce heat loss and ensure a higher collector temperature.
2.   There is no water in the vacuum tubes, so there is no fouling , no breaking .U pipe heating technology is adopted, the temperature rise is very fast. It is high efficiency and reliable.
3.   There is no restriction for the installation height, Pressurized operation and large flow make you enjoy a pleasant bath experience.
4.   The optimal design of the collector makes it visually less obstructive and compatible with existing architectural design perfectly.
