What Versleijen Oirlo does

Versleijen Oirlo is a fourth-generation family-owned Dutch mechanical-installation company headquartered in Oirlo, Limburg, founded in 1927 by Sef Versleijen as a village blacksmith and now led by directors Sjef and Paul Versleijen alongside fourth-generation owners Bob and Sven Versleijen. The firm operates through two legal entities—Versleijen Agri BV and Versleijen Installatie Techniek BV—with a team of approximately 40 professionals delivering complete installations for the agricultural sector (poultry and pig farming) and for commercial/industrial buildings (utiliteitsbouw), with a regional focus on South Netherlands and project execution extending into Belgium. Following a 2025 strategic refocus, the company has exited wet-feed (brijvoer) technology via a transfer to Kamplan BV and is winding down private-residential maintenance contracts by mid-2025.

The company's core technology is mechanical and installation engineering for livestock facilities and commercial buildings: climate-control systems (heating, cooling, ventilation with heat recovery), feed storage and transport systems (conveyor belts, augers, silos, hammer mills, mixers), water and drinking systems, manure handling and drying, sanitary installations, biomass boilers, heat pumps, and proprietary "Versleijen" control systems that integrate with OEM hardware from certified partners including Big Dutchman, Alpha Innotec, Fröling, Plettenburg, TripleEEE, Komfovent, Mitsubishi Electric, Uponor, Geberit, VDL Agrotech, and others. There is no AI/ML layer; differentiation rests on decades of domain specialization and multi-disciplinary integration capability.

Versleijen monetizes through three streams: one-time project-based installation work, recurring service and maintenance contracts (with extended hours to 20:00 on weekdays and 18:00 on weekends), and spare-parts sales from an in-house technical warehouse. Pricing is quote-based per project, with emergency service billed at 150% of standard rates after-hours on weekdays and 200% on weekends and public holidays. Go-to-market is direct B2B field sales through specialized project teams engaging clients from concept to commissioning, with no channel partners or resellers; distribution is exclusively direct, targeting mid-market and enterprise customers across pig farmers, poultry farmers, and commercial/industrial end-markets.
