Aseptic Plant Control System Replacement

The purpose for the project at this aseptic plant was to replace an existing Alfa-Laval DEC based control system with (1) Allen-Bradley ControlLogix PLC (3) Allen-Bradley CompactLogix PLCs and CTC Interact HMI software development package. The plant was unable to obtain spare parts for the DEC based system and wanted to convert to a system that spare parts were available, easy to trouble shoot for the plant maintenance department and more reliable than the current system. The control system replacement included the control of receiving, batching, HTST with separator, (3) Alfa-Laval Steritherms, (3) Alfa-Laval Steritanks, and CIP of all associated equipment.
