Selective covers are applied in the most advanced PVD vacuum chamber and
consist of composites of titanium and other metallic and gaseous ions.
Selective covers have high coefficient of absorption, low coefficient of
reflection and emission, high thermal stability and corrosive.
With our equipment we can produce selective PVD Selective covers on one or
both sides of the absorber as well absorbers flat plate and CPC
collectors for absorbers with maximum stability at high temperatures.
Solar Tubes has a cutting edge ultrasonic machine for ultrasonic welding:
-
copper wings with Selective covers with copper tube
-
aluminum with wings Selective covers with copper tube
-
aluminum with Selective covers wings with aluminum tube
-
aluminum or copper wings with Selective covers ultrasonic welded
aggregate copper or aluminum tubes
With These procedures Solar Tubes has potential to produce as copper
flat-plate collectors and aluminum flat-plate collectors and a combination
of aluminum-copper flat-plate collectors.
Solar Tubes produced as standard flat-plate collectors and flat-plate
collectors with original structures absorbers which increases the
coefficient of efficiency of the collector.
The vacuum panels that are listed in the production assortment Solar Tubes
used several types of U - type absorber where the heat transfer from the
surface of selective coating the vacuum tube to the circulating medium in
vacuum tube has a very high coefficient of heat transfer which are
additionally ratio increases the efficiency of vacuum tubes.
