HKB Ketelbouw B.V.

What HKB Ketelbouw B.V. does

HKB Ketelbouw B.V. (dba "HKB boiler solutions") is a Dutch industrial boiler manufacturer founded in 1989 and headquartered in Venlo, Netherlands. The company designs and supplies custom-engineered steam and hot water boilers for industrial clients worldwide, with a documented technical envelope of up to 120 t/h steam at 120 bar(g) and 500°C, and up to 115 MW hot water at 50 bar(g) and 250°C. The product portfolio spans nine core types — fire tube, water tube, combi, hybrid, e-boiler, waste-heat, combi waste-heat, heat recovery steam generator, and a partner-branded greenhouse boiler — supported by economisers, condensers, frequency converters, and heat-recovery subsystems.

The business operates an enterprise field-sales model with quote-based, multi-year contract pricing. Its three revenue streams are one-off capital sales of custom boilers, a rental fleet of pre-built units available from stock, and a 24/7 service department for maintenance and spare parts. The Maas-river-side location enables waterborne shipment of large fully-assembled boilers, reducing on-site assembly time and serving as a structural logistics differentiator. The firm holds 11+ certifications including PED 2014/68/EU, ASME S/H/U Stamp, ISO 9001/14001/3834-2, AD2000-HPO, VCA, EN 1090-2, and country-specific licenses for China, Russia, and Ukraine, enabling multi-jurisdictional market access.

The company's customer segment is horizontal: industrial manufacturers across a wide variety of processes requiring steam generation, hot water, or waste-heat recovery. Distribution is direct to enterprise clients globally, with a multi-language website (English, Dutch, German, Chinese) supporting international outreach. Despite 36 years of continuous operation and global reach, the organization is reported at only 6 employees, indicating a highly lean structure with likely outsourced or partner-driven fabrication.
