No. 2,834,635 CANADA 709,704 FANJET ROOF COOLING Illustration shows typical April Showers installation AUTOMATIC EVAPORATIVE ROOF COOLING SYSTEMS Spray Method The April Showers Automatic Roof Cooling Systems are designed to stop solar heat at its source by evapora tive cooling. They have been used extensively since 1934 for under-roof cooling of industrial and commer cial buildings or to reduce initial and operating costs where a true air conditioning system is contemplated or in use. In the latter case, total tonage requirements are substantially reduced and operating costs cut an average of 25 percent. April Showers Systems are completely automatic. The control thermostat is set to turn the system on at about 20 degrees above designed wet bulb temperature. A four degree drop shuts off the spray, holding the roof surface temperature at about 8 degrees above wet bulb temperature. This lowers under-roof temperatures.8 to 15 degrees. Not only is the roof temperature affected, but all supporting upright members and walls since the heavy, cool air spills down over them thus cooling them, too. It is important to note that the April Showers Sprayhead is scientifically designed to produce a fine DROP LET--not a mist. This produces a fine film of moisture on the roof which permits excellent evaporation; the action that creates lowered temperatures. April Showers operate on average city water pressure or utilize well or condenser waste water. Consumption is low, each Spray-head uses about 0.4 gpm and covers about 200 square feet. They operate an average of one minute in five; usually 15 or 20 seconds per spray pe riod. Today, there are over 25,000,000 square feet of roofs that are cooled by the April Showers Automatic Spray Method Systems. They are operating on many of the country's leading industrial plants and commercial buildings with gratifying results. April Showers fit all shapes and sizes of roofs, no special roof construction necessary, help prevent roof fires, act as lightening arrestors, add longer life to com position roofs and there is no run-off. Estimates are made without charge; however, certain pertinent data is necessary to establish the factors that govern each individual installation. Ask or write for Form E-102.

Youngquist Co.--Cornell Aeronautical Laboratory WHY WE GUARANTEE OUR SYSTEM WILL NOT CLOG BECAUSE DURING the "patented" PIERCING operation, the copper tube immediately surrounding the opening being formed, becomes dished. Immediately concentrically surrounding opening at the tube is dished radially inward. Because of the self-cleaning action pro duced by the-flow in passing through the Frusto-Pyramidal opening, this opening may be extremely small while yet avoiding the clogging tendencies of the openings now found in other spraying devices.
