John W. Cooper, Jr., P.E. has 42 years of experience as a power plant cooling tower thermal and hydraulic design engineer.  Before entering the cooling tower industry in 1976, he worked in the U.S. Space Program for 5 years in Huntsville, Alabama and in Florida.  He holds a BS degree in Biological Engineering (1970) and an MS degree in Mechanical Engineering (1971), both from Mississippi State University.

As Chief Thermal Engineer with Zurn Industries’ Cooling Tower Division in Tampa, Florida between 1976 and 1985, he learned the secrets of cooling tower thermal and hydraulic design engineering from seasoned German cooling tower engineers with Balcke Dürr Aktiengesellschaft, Zurn’s German licensor.  Under Zurn’s exclusive license agreement with Balcke-Dürr, Zurn paid royalties to Balcke on all constructed cooling towers in exchange for access to Balcke-Dürr’s proprietary thermal performance and pressure drop correlations for large cooling tower design.  As one of two persons in the Zurn organization that was granted access to the German thermal and hydraulic design information, he wrote Zurn’s complete library of FORTRAN cooling tower thermal and hydraulic design computer programs, incorporating the German correlations. Balcke-Dürr Ag, originally named Balcke Maschinenbau Aktiengesellschaft, was founded in Bochum, Germany in 1894 by Hans-Joachim Balcke, the inventor of the natural draft cooling tower.  It is noteworthy that John has enjoyed the benefits of being the only cooling tower thermal design engineer in the United States to have been apprenticed by Balcke engineers.

For the past 27 years, operating under the Corporate name, John Cooper & Associates, P.A., he has served the needs of the international electric power generation industry as an independent cooling tower consulting engineer, in matters relating to the thermal performance enhancement and practical operation of large natural draft and mechanical draft cooling towers.

On 32 occasions, over the past 33 years, John has shared his specialized cooling tower expertise with power plant engineers and managers in the United States and in Australia in the form of formal one or two-day training courses.
