Design/build of process water cooling system at a sophisticated testing facility. The enhanced 12-cell 300,000 gpm process water cooling complex features massive 40-ft. fans, dozens of 30-inch valves, specialized pumps, intricate piping, complex hydraulics, and state-of-the-art electrical/instrumentation systems. Caddell accomplished the design/build of two new cooling tower units (each with four cells) over an existing basin to significantly increase cooling capacity without modifying the basin structure itself using a unique flared tower design. Caddell also added a completely new basin and cooling tower unit, and brought all modifications and new construction on-line without interruption to Arnold’s critical testing activities. To regulate the cooling operations, Caddell installed a state-of-the-art control system that also manages the water system for the entire base.
