Industrial Automation & Control Panels

Advanced automation, motor control and synchronization panels for industrial efficiency.

We build custom automation and control panels to your project: command panels, motor start-up and protection panels, capacitor bank synchronization, soft starters, and variable frequency drives. We assemble and wire the panel with gear from the leading manufacturers, ready to integrate into your production process.

Project scope

Control panels for production lines, motor start-up and protection panels, capacitor bank synchronization, soft starters, and variable frequency drives.

Expected gains

Higher energy efficiency, reduced downtime, precise process control, and full traceability of critical variables.

Typical applications

Manufacturing, packaging lines, water treatment, industrial HVAC, pumping, and modernization of legacy infrastructure.

From switchboard to automation, under one roof

As panel builders in Porto, we build the automation panel and the switchboard that powers it under one roof — gear sizing, assembly, wiring and testing by the same team. We work for clients across Portugal and the European Union, with equipment from the main global manufacturers, and deliver a test report and full technical documentation.

How we build it

  1. Project analysis

    We receive the client's diagram or specification and define the panel's gear list.

  2. Gear selection and sizing

    We select and size the components (PLC, drives, contactors, protections) to the project.

  3. Proposal and negotiation

    We present the technical and commercial proposal — scope, gear, lead time and price — and fine-tune the details with you before manufacturing starts.

  4. Mechanical fabrication and wiring

    Structure assembly, gear installation and labelled wiring, by qualified technical staff.

  5. Testing and verification

    Electrical and functional testing of the panel, with visual and dimensional checks.

  6. Documentation and delivery

    Test report, technical documentation and CE marking. Delivery to the client's site.

Frequently asked questions

What types of industrial automation do you build?

Motor control panels, synchronization panels, panels for PLCs and variable frequency drives, automation for production lines and industrial processes.

Which PLC and equipment manufacturers do you work with?

We select the equipment based on the project and the client's requirements. We work with the main global manufacturers of PLCs, drives, contactors, and protections.

Can you integrate automation into existing systems (retrofit)?

Yes. We implement retrofit solutions in existing systems, executing the manufacturing and assembly of the panel.

How long does an automation panel take?

It depends on complexity, but typical manufacturing is 3 to 6 weeks. We always give a firm lead time in the proposal.

What documentation do you deliver with the panel?

A test report and the panel's technical documentation, with CE marking.
