In most of the above cooling tower upgrade projects, John Cooper & Associates, P.A.:

A.      Prepared Color-Coded Exit Air Temperature and Velocity Mappings to isolate sources of thermal performance  deficiency.

B.       Developed a computer model of the hydraulic performance of the entire cooling tower water distribution system. The computer model was used as a design tool for optimization of the water distribution system.

C.      Prepared detailed engineering drawings that defined the modifications to the cooling tower fill and water distribution systems.

D.      Prepared a complete Bill Of Materials for the Upgrade Design Modification Package.

E.      Documented all of the above in one or more bound Formal Upgrade Design Reports that provided detailed instructions regarding implementation of the Design Modification package.
