What A. de Jong does

A. de Jong is a privately held Dutch family business founded in 1877, currently in its fourth generation of family ownership and led by Algemeen Directeur Albert de Jong. The group operates from three regional locations — Schiedam (headquarters and machine factory), Rijswijk (A. de Jong Installatietechniek West), and Zaandam (A. de Jong Installatietechniek Noordwest) — and employs more than 250 people across design, installation, product development, and maintenance functions. It is one of the 300 oldest family businesses in the Netherlands and has been recognized by Deloitte as a Best Managed Company for seven consecutive years through 2018.

The business is organized in two core divisions. A. de Jong Installatietechniek designs, builds, and maintains complete climate and building installations for utility buildings in the Netherlands — covering mechanical engineering (werktuigbouwkunde), electrical engineering, measurement and control technology, prefabrication (WKO geothermal systems, BIM-coordinated design), and multi-year facility management contracts. Its end markets include commercial offices, hospitals, schools, hotels, government buildings, logistics, food processing, and industrial customers, with named clients such as Gemeente Rotterdam (71-building portfolio), HNK Rotterdam Alexander, Quooker, Intralox, Protix, Rotterdam World Gateway, Tacx, and Lamb Weston. The second division, De Jong Energy Services (incorporating De Jong Combustion and R&V Engineering, both acquired in 2008), supplies industrial burner systems, skid-built energy and process solutions, and process automation globally; the Combustion Systems unit is described as a world market leader in industrial burner technology and is investing in 100% hydrogen-ready burner technology for the energy transition.

A. de Jong generates revenue through a mix of one-time project-based installation contracts won via competitive tenders and direct enterprise field sales, plus recurring managed-service maintenance agreements (e.g., 24/7 service at RWG, full portfolio management for Maatschappelijk Vastgoed Rotterdam). Pricing is project-specific and quote-based, with no public disclosure. The industrial division earns revenue from hardware sales of burner systems and skids, plus engineering and consulting services. Distribution is exclusively direct B2B: enterprise field sales teams in the Netherlands for the installation business, and global direct sales through the De Jong Combustion and R&V Engineering brands for industrial clients. The company also operates a customer portal (Klantportaal) for service management and an in-house Academy for workforce development.
