TZ series Solar Collector with Solar Keymark

TZ series Solar collectors areconnected 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.
