S5 to S7 400 upgrade


The existing CIP system was designed for supplying a single plant requirements, it did not meet current safety or operational requirements. A new CIP system was required to meet all current safety standards, be robust and repeatable, run in full automatic mode and have comprehensive recipe management system.
The new CIP system needed to incorporate a larger capacity for additional plant cleaning. This required a comprehensive control system to deliver CIP for multiple plant and the additional safety requirements. A complete recipe management system to supply different plant with different requirements.

1. Develop Independent CIP skid (Clean In Place and drying) control for delivery of CIP to two separate plant entities.
2. Interlock two plants so only one can control CIP at any given time.
3. Batch recipe system (S88) for flexible delivery of CIP for different plant requirements
4. SIL 4 Requirements for safety interlocks between two separate plants utilising dedicated Pliz safety PLC.
5. Recipe development and management.
6. Install and test to Gamp 5 standards.
