TZ series of solar collector enjoys great reputation in Europe countries. We have EN12975 and Solar Keymark.

TZ series Solar collectors are connected with existing heating supply device, whichis main part of solar water heating system. The selective coating on the inner coverof 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.
