FEDINC provided full-service engineering for a Cooling Pond Spray System at Hines Energy Complex. Design included engineering and specification of spray aeration equipment and supporting integral electrical systems (control panels, submersible electrical leads, etc., integral with mechanical equipment) for installation by the owner in the existing HEC N-16 Cooling Pond for control of thermal loads. The design accommodated complete installation of electrical systems and phased installation of spray aeration equipment as additional cooling capacity became necessary. Mechanical and integral electrical equipment selection was based on the best evaluated combination of low cost, high capacity, cooling efficiency, ease of installation, ease of operations and maintenance, operating reliability, warranty, and lower power consumption. All electrical systems met all applicable IEE, NEMA, and NEC codes.
