1.The evacuated tubes which are slid onto a U-shaped heat transfer unit absord to absorb the sun energy and transform it into heat. The water or frost protection agent-water mixture flows through the U-shaped conduit.As a result, the liquid is heated. When the required tempetature is reached, the pump in the solar circuit is activated by the controller and transports the heat to the hot water storage tank or the heating system

2.Suitable for mains pressure water

3.Since there is no water in the tubes itself, the tubes will not break in winter

4.System is reliable and efficient

5.The collector is mountable on sloped or flat roofs or on a facade. The installation is the most flexible since it can work well in any installation angle

6.It can be combined with an existing pipeline

7.It can operate even if one tube breaks
