What Ofatec does

Ofatec SA is a Swiss power reliability and energy conversion specialist founded in 1980 and headquartered in Puidoux, Switzerland. The company provides a multi-vendor portfolio spanning static and dynamic UPS systems (via Riello and Piller), generator sets (Inmesol, Margen), batteries (AGM, Gel, Lithium), voltage stabilizers, power converters, static transfer switches, cogeneration units (Kubota, MAN engines), and renewable energy solutions including Ecowatt hydroelectric turbines and Enogia ORC modules. Service offerings include preventive maintenance, thermography inspections, equipment rental, generator renovation, and circuit breaker testing. Ofatec serves B2B customers across financial and banking institutions, data centers, hospitals and healthcare facilities, and industrial manufacturing sites, with secondary exposure to pharma, transport, telecom, and aeronautics.

The business model combines one-time equipment sales with recurring maintenance services and a smaller equipment-rental stream for events and temporary applications. Distribution is direct B2B within Switzerland only, supplemented by a biennial Open House event — most recently in 2025 with over 120 attendees — that functions as both a customer retention mechanism and a partner showcase. Technology is supplied through long-standing OEM partnerships rather than in-house R&D, with Ofatec acting as a value-added Swiss distributor and system integrator.

In May 2026, Ofatec announced it had joined Groupe Gérard Perrier Industrie, a diversified industrial group, while retaining its existing contacts, services, and brand identity. The ownership transition is the most significant recent corporate event and signals a potential new growth phase via group-level resources, though Ofatec's geographic scope remains Swiss-domestic and no AI-native capabilities, app products, or external funding rounds are present in the record.
