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
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.
