Detailed Product Description

TZ series Pressurized Solar collectors are connected with existing heating supply device, which is main part of solar water heating system. The selective coating on the inner cover
of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes. The heat then passes through the heat exchanger. It is also a kind of heat collecting device which can be used separately.
