Manufacturing Custom Control Panels for Quality, Compliance, and Reliable Operation

At Hallfield Controls, we provide custom control panels for customers who need more than basic panel fabrication. Since 2009, we have supported electrical, mechanical, and industrial engineers with panel manufacturing backed by controls engineering, detailed documentation, and real-world startup experience. 

Whether you need a one-off custom UL508A control panel, support for a larger automation project, or repeat builds for an OEM application, we provide the build quality, technical support, and compliance confidence required to keep your project moving.

A UL508A-Listed Facility Backed by Engineering Experience

Hallfield Controls operates a UL508A-listed facility (File #E359971) in Big Lake, MN, for custom enclosed industrial control panels and control wiring systems. What sets our panel shop apart is that it is supported by in-house engineering and design, programming, and troubleshooting experience. That means we understand how systems are intended to function, how they will be installed, and how they need to perform once they reach the customer site. 

We engineer and build systems to strict UL508A standards, automatically ensuring full compliance with NFPA 70 (NEC) electrical codes. We seamlessly adapt our builds to meet NFPA 79 or IEC standards when your project demands it, all while maintaining absolute brand flexibility across major platforms like Allen-Bradley, Siemens, and GE.

  • Machine Breakdown and Troubleshooting: We offer expert-level resolution for failed automation components.
  • Automation Upgrades and Modernization: We help you redesign or upgrade outdated control systems to improve equipment longevity and overall system efficiency.
  • Machine Safety Upgrades: Our team implements controls-related safety improvements and interface updates to support safer, more reliable equipment operation.
  • Capacity Augmentation: We act as an outsourced electrical engineering department when your internal team is at maximum capacity or lacks specific controls expertise.

Build Quality That Supports Installation and Commissioning

Every panel we manufacture is built with a focus on quality, consistency, and long-term serviceability. We design and build systems, so installation, maintenance, and future troubleshooting are easier for the customer team. That includes careful panel layout, organized wiring practices, and attention to the details that matter once the equipment reaches the field. By utilizing precise page-and-line grid numbering, we ensure your maintenance technicians can instantly cross-reference any physical wire or component to its exact location in the schematics during troubleshooting.

Our manufacturing capabilities include:
  • Panel fabrication and assembly
  • Page-and-line grid labeling for wires and components
  • Control wiring systems
  • Component supply and procurement support
  • Electrical schematics, panel layouts, enclosure layouts, and bills of material (BOMs)
  • Drive configuration for VFD, servo, and related systems
  • Controller configuration for temperature, process, and batch applications
  • PLC and drive programming support
  • Low-to-medium volume repeat manufacturing for build-to-print and custom variations

Factory Testing That Reduces Startup Risk

For one-off custom systems, we perform full Factory Acceptance Testing (FAT) and invite customers to witness the validation process at our facility. For our repeat OEM applications, we enforce strict internal quality control with 100% product testing to a defined procedure on every single unit shipped, guaranteeing that every enclosure leaves our floor wired and assembled correctly.
