Service

Custom control panels, built to your spec

From single-zone heater panels to 32-zone extruder arrays — designed, wired and tested in our Spartanburg shop.

What we build

Engineered, not assembled from a kit

Every panel starts with your process. We select components, lay out the enclosure, program the controllers and wire it all — then test before it ships.

Multi-Zone Heating Panels

Up to 32 independent PID loops with SSR or SCR power switching, alarm outputs and auto-tune — for extruders, presses and oven arrays.

Safety & Interlock Systems

Over-temperature protection, phase-loss relays, E-stop circuits and SIL-rated safety controllers independent of the primary loop.

Process & Sequencing Panels

PLC- or relay-based logic for ramp/hold profiles, CIP sequences, conveyor speed control and production-count automation.

Retrofit & Modernization

Replace obsolete relays, dead controllers or non-documentable wiring with a modern panel — same footprint, current code compliance.

Our process

From spec to shipped in weeks, not months

We keep panel work under our roof. You can walk through the shop, review layouts and see your panel tested before it leaves.

  • Design review with your engineers
  • Component selection (Watlow, Eurotherm)
  • UL-recognized construction per NFPA 79 / NEC
  • Factory acceptance testing before shipment
  • As-built documentation: diagrams, I/O lists, BOM

Why MAHC panels

Integrated thermal knowledge, not just electrical

A panel shop that doesn't understand heating elements, sensor behavior or power-switching dynamics will wire the wrong components. We do all three under one roof.

Element-matched

Watt-density, voltage and duty-cycle are factored into SSR sizing and fuse selection from day one.

Sensor-aware wiring

Thermocouple polarity, cold-junction compensation and RTD lead-wire resistance handled correctly.

Safety redundant

Independent over-temp trips, phase monitoring and hardwired interlocks — not just software alarms.

Supportable

Wire numbering, component labels and full documentation so your team can maintain it for decades.

FAQ

Custom control panel FAQ

Ideally yes, but we can work from a description. A basic P&ID, zone list with setpoints and available power (voltage, phase, available FLA) are enough to get started. We'll refine the design together before wire.

Absolutely. Our panels follow NFPA 79, NEC and your local Authority Having Jurisdiction. We include nameplate data, component UL listings and documentation packages that satisfy inspection.

That's common. We can trace and rewire in-place or build a drop-in replacement. Send photos and the voltage/power rating — we'll scope whether it's a component swap or a full rebuild.

Yes. We design and build the panel in Spartanburg, ship it ready for install, and support commissioning by phone or video. For complex multi-zone installations, we can schedule an on-site start-up.
