What Hunter & Van Twist does

Hunter & Van Twist NV is a Belgian specialist in backup power and combustion-engine systems, headquartered in Aartselaar and operating as a subsidiary of the family-owned Koninklijke Van Twist BV (Netherlands). Founded in 1928, the company supplies, installs, repairs and maintains diesel generator sets (2.5–4,500 kVA), gas generators (56–320 kVA), hydrogen generators (100–200 kVA), Perkins industrial diesel motors, custom control panels and fuel storage systems, serving enterprise customers in healthcare, data centers, logistics, chemicals, retail, telecommunications and industrial gas — including imec, Johnson & Johnson, Aurubis, Solvay, Air Liquide, Delhaize, Engie, Digital Realty, VOO, Agfa-Gevaert and Fluxys.

The technical platform rests on long-standing OEM partnerships (Perkins since 1938, Rehlko since 2021) plus in-house engineering of hydrogen combustion motors and microgrid configurations. Service delivery is supported by VCA* and ISO 9001 certifications, a 1,000+ active maintenance-contract base, and a training offering that doubles as customer lock-in. Director Eddie Bormans runs the Belgian operation under sixth-generation family owner Norbert van Twist, with the parent group employing 170+ across Belgium, the Netherlands and Germany and the Belgian entity accounting for 30+ energy specialists.

Revenue is generated through three interlocking streams: (1) capital-equipment sales of generator sets, motors and fuel systems tied to project installation work; (2) recurring managed services, inspections, overhauls and parts under multi-year maintenance contracts; and (3) training and engineering services. Go-to-market is direct enterprise sales, with the website disclosing more than EUR 10 million in turnover at the Belgian entity, complemented by group-level geographic reach into Germany and the Netherlands through sister companies.
