Alro Engineering, the Valais-based specialist in industrial automation

Founded in 1988 in Martigny, Alro Engineering has established itself as one of the leading engineering firms specializing in industrial automation in French-speaking Switzerland. With more than 40 employees based in Martigny and Monthey, the company offers comprehensive solutions to its industrial clients—from feasibility studies and design through commissioning and maintenance. Pharmaceuticals, chemicals, food processing, and biotechnology: Alro Engineering operates in demanding sectors where compliance with safety and quality standards is non-negotiable.

Alro Engineering’s services cover every stage of an industrial automation project. The company gets involved as early as the study and design phase, incorporating the validation of technical installations in accordance with GAMP, ATEX, or SIL standards. It then handles electrical schematics, equipment selection and calibration, followed by the installation and programming of programmable logic controllers (PLCs), safety controllers, and human-machine interfaces (HMIs).

Commissioning is based on process simulations conducted in advance, which helps minimize unforeseen issues on-site and reduce plant downtime. Alro Engineering also provides maintenance for these systems, including preventive maintenance, as well as the implementation of communication systems between its clients’ various facilities.

Industries Subject to Strict Requirements

Alro Engineering is particularly active in four industrial sectors, each subject to specific regulatory constraints. In the pharmaceutical and biotechnology sectors, the company follows GAMP (Good Automated Manufacturing Practice) guidelines, which govern the international validation of automated systems. In particular, it incorporates the requirements of the latest version of these guidelines, which places risk analysis and management—for patients, data, and products—at the heart of the relationship between users and suppliers.

In the chemical industry, Alro Engineering has developed specialized expertise in explosion-hazard areas through numerous projects carried out in this sector. This experience enables the company to meet the requirements of ATEX and SIL standards and to provide compliant, reliable solutions tailored to each client’s specific constraints.

In the food industry, the company applies the methodological rigor acquired in the pharmaceutical sector to automate continuous processes and batch production in accordance with the ISA S88 standard. Finally, Alro Engineering relies on a team of experienced engineers capable of managing short cycle times and all types of drives, whether linear or rotary motors, cams, or actuators.
