Abstract
An evaporative condenser having a cylindrical fiberglass housing which provides a circumferential air flow across a plurality of concentrically oriented spiral condensing coils. The planar spiral coils are generated through the compression of a conical winding of tubing formed about a multi-tiered platform, to form an evenly-spaced spiral condensing coil. Each layer of tubing is affixed to a plurality of radial braces, which provide the evaporative coils with sufficient structural integrity to be individually employed. A method and apparatus for producing spiral coils having uniform spacing between adjacent revolutions.
