Our UL Control Panel Fabrication Services
ACI can handle every phase of your panel project from design through delivery .
Custom UL Panel Design
Our engineers design any control panel, console, or MCC to your exact specifications using the latest version of AutoCAD Electrical. Every design package includes:
- Panel layouts and enclosure specifications
- Detailed bills of material with vendor part numbers
- Network architecture and P&IDs
- Clear, easy-to-read wiring diagrams with cross-referencing and detailed notes
- UL panel classification design for any required standard
UL Control Panel Fabrication & Assembly
ACI's craftsmen build panels of all types and sizes—from single standalone enclosures to large multi-panel installations. Our 12,000-square-foot shop includes a dedicated testing and staging area for power tests and factory acceptance testing (FATs). Panel types we fabricate include:
- Standard industrial UL control panels
- HMI panels and operator stations
- Remote I/O panels
- Motor control centers (MCCs)
- Large consoles and custom enclosures
- Portable equipment panels
In-House Testing & Factory Acceptance Testing (FAT)
No panel leaves our shop without passing a comprehensive test procedure performed by our engineering team. This includes:
- Final inspection of all components
- Point-to-point testing of every wire
- Tug testing for connection integrity
- Power tests and full factory acceptance testing (FAT)
This rigorous process reduces installation time and start-up time in the field—so your team hits the ground running.
UL Panel Certifications: From Standard to Hazardous Location
ACI is certified to build numerous types of UL-listed control panels. While many panel shops can build to UL 508A for general-purpose industrial applications, very few have the expertise to build panels to UL specifications for hazardous environments. ACI does and delivers these panels to OEMs nationwide.
UL Certifications We Build To
|
Certification |
Application |
|
UL 508A |
General-purpose industrial control panels for non-hazardous locations |
|
UL 698A |
Panels in ordinary locations with intrinsically safe circuit extensions into hazardous (classified) locations |
|
UL NNNY |
More stringent standard for panels in Class I hazardous areas with flammable gas, liquid, or vapor present |
|
Intrinsically Safe (IS) |
Panels designed to prevent ignition in explosive atmospheres by limiting energy in field circuits |
|
Purged & Pressurized |
Panels using positive pressure to exclude hazardous gases from the enclosure interior |
C/US UL Listed — ACI panels carry the C/US UL Listed mark, accepted by authorities having jurisdiction (AHJs) in every U.S. jurisdiction and recognized in Canada.
Hazardous Location Expertise
ACI has many years of experience designing and building panels for pharmaceutical pilot plants, chemical processing facilities, and other hazardous environments—as both purged and pressurized systems and intrinsically safe (IS) configurations.
Real-World Example: A recent project for a major pharmaceutical company required 67 panels of varying sizes—including main, HMI, remote I/O, and portable equipment panels—with the majority built to purged and pressurized or intrinsically safe (IS) specifications. ACI's engineering and installation teams were involved from initial design through start-up, delivering a successful project closeout on schedule.
