Solar Collector / Direct-instantaneous U-type
The vacuum- tube solar collectors CAU type works with directly heating the coolant in the heat exchanger- U tube- located in vacuum tube.
They are intended for the extraction of domestic hot water.
Their heating element is copper tube with aluminum absorber, isolated from the environment with the help of double pre-evacuated between the layers tube. That gives the collector the ability to work even in the winter. On the inside glass tube is applied an selective coat that caches the solar radiation even in cloudy weather.
The form “double X” of the aluminum absorber of the U- tube, also the dry connection between the tubes, makes the mounting under different angle possible, including vertical installation.
The vacuum tube is made from borosilicate glass and is resistible to hail with grains size to 25 mm.
Achieved maximum extraction of solar energy per day, from one CAU 12 – according to test made at 07.06.20120: http://sunenergy.free.bg/online/vf.html
