Otterman Techniek

What Otterman Techniek does

Otterman Techniek is a family-owned technical installation services company based in Eastern Netherlands (Oost-Nederland) and a member of the Morrenhof-Jansen family of companies, which also includes Kosse Installatietechnieken, Installatiebedrijf Dick Sjabbens, and a majority stake in CIUS Techniek (heat pumps). The Morrenhof-Jansen group traces its origins to 1980 and operates under a shared family-business structure with combined experience exceeding 100 years across the affiliated entities.

The company delivers multi-disciplinary technical installation services across both residential (Particulier) and commercial (Zakelijk) markets. Its functional scope covers electrical engineering (elektrotechniek), mechanical/HVAC (werktuigbouwkunde, CV-klimaatbeheersing), data networks, security, domotics, ventilation, swimming-pool technology, building management systems (gebouwbeheersystemen), and prefabrication (prefab). It also operates a sustainability/energy-transition practice spanning heat pumps, solar panels, home batteries (including SolarEdge and Huawei product lines), smart power sensors, and energy storage. Commercial vertical coverage explicitly includes housing (woningbouw), utility (utiliteit), agriculture (agrarisch), and healthcare (zorg).

The business model is project-based and quote-driven rather than publicly priced, consistent with a regional installation services firm. Revenue is generated through new-construction installs, renovation projects, ongoing maintenance contracts (onderhoudscontracten / contractbeheer), and service-call revenue (storing melden). Group-level brand credibility is anchored by the 'Installatiebedrijf van het Jaar 2023-2024' award conferred on Morrenhof-Jansen. No revenue, headcount, or financial metrics are disclosed for Otterman Techniek as a standalone entity, and the company has no public listing.
