SCOPE OF SERVICES
Shambaugh & Son completed the installation of a two-stage/three suction level refrigeration system. The initial installation consisted of 18 compressors that ranged in size from 300-1000 HP. Twelve large evaporative condensers served to reject this load to the environment. Nineteen 75,000 cfm rooftop HVAC units and over 10 miles of refrigeration piping service the various process areas to ensure proper temperatures and hygienic filtration. A centralized control system allowed for critical process temperature control and the integration of an ammonia monitoring system.
