... plate absorber is fabricated using the latest ultrasonic welding machinery and a specially developed welding technique that increases the heat transfer from the absorber to the heat transfer fluid in the copper register. Our flat plate and facade collectors feature our unique absorber covered with a high quality, selective PVD coating. Our Evacuated Tube Collectors are among the most efficient available, featuring double walled glass with its own selective PVD coating. Each U-type copper pipe is also welded to its own absorber with selective coating, increasing the heat transfer potential.
