SunBurst Absorber Plates

example4

The extraordinary SunBurst all copper absorber plate is the heart of each SunEarth liquid flat plate collector.  Each SunBurst absorber is constructed of a thick .008 roll- formed copper sheet that is continuously soldered to a Type-M copper header and riser piping assembly utilizing a non-corrosive solder paste.  The riser piping is a minimum 1/2″ O.D. Type-M copper tubing.  The header piping  is a minimum  7/8′  O.D., 1 1/8″  O.D. or 1 5/8″ O.D.  Type-M copper tubing depending upon the collector model chosen.  The riser to header bond is made with a phosphorous brazing alloy with no less than 15% silver content and conforms to the American Welding Society’s BCuP-5 classification.   The SunBurst absorber plate is designed for operating pressures up to 160 psig.

The SunBurst absorber has been independently tested by U.L Laboratories to UL Standard 1279, Section 30.2 for liquid containment.   The absorber was submitted to an internal hydrostatic pressure of 2.5 times the rated positive pressure of 160 psig, or 400 psig, for one hour without evidence of leakage or rupture.
