Business areas
From the service offering — technical scope covered by our teams.
- Supply and installation of medium- and low-voltage equipment.
- Low voltage: fire safety, intrusion, video / remote monitoring (including with Honeywell as a partner).
- Design and delivery of lighting and distribution installations.
- Supply and installation of distribution switchboards: main LV panels, transfer switches (manual, semi-automatic, automatic), etc.
- Industrial control panels: pumping, direct-on-line, star-delta, soft starters, etc.
- Maintenance of equipment and installations: generators, power factor correction, industrial automation (drives, PLCs), etc.
- Protection of assets and people: lightning protection, surge protection, fire detection, intrusion.
- Technical and energy studies on industrial sites.
- Consulting, assistance and follow-up for industrial clients.
Diagnostics & audit
Diagnostics and audit for electrical and communication equipment and networks: performance improvement, consumption reduction, renovation hotspots, process efficiency, technology upgrades and contractual compliance.
- Define actions to improve system performance and efficiency.
- Help reduce energy and raw-material consumption.
- Highlight areas that need renovation and assess criticality.
- 4-step methodology: needs and site constraints; network robustness and reliability; criticality and service policy per switchboard; shared action plan and recommendations.
Pre-project consulting & engineering
Pre-project consulting: pre-diagnostic, diagnostic and feasibility study (technology, technical, environmental and economic constraints). Vendor-neutral engineering with equipment best suited to the requirement.
- Pre-diagnostic: clarify needs and rank performance criteria for future functions.
- Diagnostic: identify causes of under-performance.
- Feasibility study: factor in technology, technical, environmental and economic constraints.
- Multi-vendor solutions with detailed reporting: architecture, variant performance, consumption and lifecycle simulation, lead times and resources, safety and environmental impact.
Installation, commissioning & maintenance
Installation and commissioning to applicable standards, project management, progress reporting, acceptance testing and operator training. Then corrective and preventive maintenance, audits, maintenance plans, on-call support and SLA contracts.
- Installation: experienced teams, supply of equipment when specified in the study, schedule adherence, reporting through to handover.
- Acceptance tests and operator training on installed systems.
- Preventive maintenance per AFNOR FDX 60-000 (levels 1–4, MV/LV and transformers, annual checks, major overhauls, dissolved-gas analysis for oil-filled transformers).
- Repairs, retrofit of obsolete parts while preserving the original configuration, spare-parts stocking advice.
- Tailored maintenance contracts (SLA): response times, spare parts or replacement equipment, emergency support, warranties by contract tier.
- 24/7 on-call for emergencies (production loss, safety of people and assets).
