MCC Systems for Control of Paint Facility

MCC Systems for Control of Paint Facility Northern Ireland


The client was undertaking an extension to their factory, which included installing a new state-of-the-art and fully automatic spray paint facility. Due to the size of the plant, PAC Switchgear & Control used technologically advanced solutions to design suitable MCCs for wiring and control logistics.


This project included many challenges due to the layout of the plant – the design team at PAC Switchgear & Control had to give special consideration to the logistics for the field wiring and the complexity of the controls.

The total plant consisted of 77 variable speed drives, 400 proximity sensors, and 200 solenoid valves, which control five spray booths, two ovens, overhead crane systems, and a full overhead conveyor system that runs throughout the entire plant.

The system was designed to have three main locations: the primer area, top coat area, and master MCC. The master MCC had the main PLC and SCADA system, with the other two areas using remote systems. Installed within the master MCC was a safety PLC, which also communicated to the two remote MCCs. The safety of the plant was not segregated and could be programmed with flexibility.


PAC Switchgear & Control delivered each MCC system to meet the project scheduling requirements successfully.
