Custom HVAC Control Panel Design & Fabrication
M-Tech Control designs and manufactures custom HVAC control panels for air handling units, fan systems, heating applications, and building automation integration. Each HVAC control panel is engineered to the specific demands of the system, accounting for motor loads, control sequences, environmental conditions, and applicable electrical codes.
Our HVAC panel capabilities include:
- Air handling unit (AHU) control panels: Single-speed, multi-speed, and VFD-integrated fan control
- Supply and exhaust fan panels: Standalone and networked configurations
- Heater and heat trace control panels: Setpoint control, safety interlocks, and alarm outputs
- Custom HVAC electrical panels: Built to mechanical contractor, OEM, or systems integrator specifications
Every custom HVAC control panel is designed in-house, fabricated by our assembly team, and fully tested before shipment. We work with HVAC contractors, mechanical engineers, building automation integrators, and OEMs to deliver panels that install cleanly and perform from day one.
Quality Built Into Every Panel We Make
At M-Tech Control, quality control is more than a final inspection–it's built into every step of the manufacturing process. We apply over 100 individual quality checkpoints throughout every custom control panel build, covering:
- Each panel is certified UL508A/cUL508A. They are also available with UL698A certifications (Intrinsic Safety)
- Design accuracy and BOM compliance verification
- Correct component installation, orientation, and spacing
- Wire sizing, routing, color-coding, and labeling
- Torque verification and termination integrity
- Functional testing and pre-shipment quality sign-off
Every panel that ships from our facility is built exactly to customer specifications — with no shortcuts, no exceptions. That standard applies whether we're building a single prototype panel or fulfilling a multi-unit production order. We are proud to serve multiple industries, such as industrial facilities, water/wastewater, data centers, OEMs, systems integrators, HVAC contractors, crane and gantry operators, machinery control operators, and engineering firms, all of whom rely on M-Tech Control because we treat their specifications as a commitment, not a starting point.

Frequently Asked Questions
What are the best custom control panels for high-volume manufacturing?
The best custom control panels for high-volume manufacturing are those engineered around reliability, standardized wiring practices, and ease of long-term servicing — because in a continuous production environment, downtime carries a direct cost. The most effective panel types for high-volume applications include:
- PLC control panels: Programmable logic controllers with modular I/O architecture provide flexible process control, real-time monitoring, and scalable automation across production lines
- Custom VFD (Variable Frequency Drive) panels: Enable precise motor speed control, reducing mechanical wear and energy consumption across high-cycle machinery
- Combination motor starter panels: Ideal for production lines with multiple motor loads that require coordinated starting sequences and overcurrent protection
- Customized MCC (Motor Control Center) assemblies: Centralize motor control and power distribution in large-scale manufacturing facilities for cleaner power management and simplified maintenance access
- Machinery control packages: Purpose-built panels designed around a specific machine's operating sequences, safety interlocks, and I/O requirements
For high-volume environments, panel standardization across a production line is equally critical, ensuring every unit is built identically so troubleshooting, replacement, and spare parts management remain consistent. M-Tech Control designs and manufactures custom industrial control panels to exact specifications, applying 100+ quality checkpoints to every build. Contact our engineering team to discuss your production application.
What does the custom control panel design and manufacturing process involve?
Custom control panel design and manufacturing follow a structured, multi-stage process to ensure every panel is accurate, compliant, and built exactly to specification. At M-Tech Control, our process includes:
- Application and requirements review: We begin by reviewing your application requirements, operating environment, load specifications, and any applicable code standards before engineering begins
- Engineering and design development: Our in-house team produces complete panel layout drawings, electrical schematics, wiring diagrams, and a full bill of materials (BOM) developed specifically to your requirements
- Customer design approval: You review and approve all design documents before fabrication begins — no panel enters production without your explicit sign-off
- Panel fabrication and assembly: Our manufacturing team builds the panel through 100+ quality control checkpoints covering component mounting, wire routing, terminations, color-coding, and labeling
- Functional testing and quality verification: Every panel is tested and verified against the approved design before it leaves our facility
- Shipment and delivery: Panels are carefully packed and shipped to your facility or installation site
Whether you supply your own drawings or need M-Tech Control to develop the design from the ground up, the process is built around accuracy, accountability, and your project timeline.
What is the difference between control panel fabrication and control panel manufacturing?
Control panel fabrication and control panel manufacturing are closely related terms often used interchangeably, but they describe distinct scopes of work:
Control panel fabrication refers specifically to the physical build — taking an approved design and assembling it into a finished, working panel. This includes enclosure preparation, component mounting, wiring, terminations, and labeling. Fabrication is execution: it assumes the design already exists and has been approved.
Control panel manufacturing is a broader term that encompasses the full end-to-end process — from initial design and engineering through fabrication, quality testing, and delivery. A control panel manufacturer manages both the design and the build under one roof.
At M-Tech Control, we provide complete control panel manufacturing services: our in-house engineering team develops the design, and our fabrication team executes it. We also offer fabrication-only services for customers who supply complete, approved drawings and simply need a precision build partner. Whether you need a full design-build manufacturer or a dedicated panel fabrication shop to execute your existing specifications, M-Tech Control supports both.
What certifications and standards should a custom industrial control panel meet?
Custom industrial control panels in the United States are typically required to comply with one or more of the following standards, depending on the application, industry, and installation environment:
- UL 508A: The primary U.S. standard for industrial control panels, covering construction requirements for panels in non-hazardous locations. UL 508A compliance is required or strongly expected on most commercial and industrial projects, and many facility owners and contractors require it as a condition of installation
- NFPA 79: Governs electrical standards for industrial machinery, covering wiring methods, conductor sizing, and protection requirements specifically for machinery control panels
- NEC (NFPA 70): The National Electrical Code establishes the baseline electrical installation requirements that govern panel wiring practices across applications
- NEMA enclosure ratings: Define the environmental protection classification of the panel enclosure (e.g., NEMA 4 for indoor/outdoor washdown environments, NEMA 7 for Class I hazardous locations, NEMA 12 for industrial dust and drip protection)
M-Tech Control's custom control panel design and fabrication process is built with code compliance in mind from the first line of the design. Our engineers account for applicable standards during the design phase, and our fabrication team builds to those requirements — so your panel is compliant before it ships. Contact us to discuss the specific standards your application requires.
