What Danstoker does

Danstoker A/S is a Danish manufacturer of high-performance industrial boilers founded in 1935 and headquartered in Herning, Denmark. Operating as a wholly-owned subsidiary of India's Thermax Ltd. since November 2010, the company designs, manufactures and services a broad portfolio of custom-engineered boiler and heat-recovery equipment — including biomass-fired boilers (its core differentiator in the 2–50 MW segment where it claims world-market leadership), waste-to-energy boilers, oil & gas-fired shell & tube boilers (800–50,000 kW), low- and high-voltage electric boilers (400 kW–9,000 kg/h steam), thermal oil boilers, waste heat recovery boilers, exhaust gas boilers, combined steam boilers, and air pollution control systems. Technical differentiation includes the proprietary Danblast automatic pneumatic cleaning system, a unique multi-pass waste-to-energy design, and pressure-parts engineering performed in close cooperation with leading combustion and fuel-handling equipment suppliers. Manufacturing is dual-sited in Denmark and Poland (Danstoker Poland Sp. z o.o., acquired 2017), with additional group entities in the UK (Danstoker (UK) Ltd.), Germany (RIFOX – Hans Richter GmbH) and broader Thermax Group reach into India.

The business model is project-based and custom-quoted; pricing is not public. Revenue is generated primarily through hardware sales of new boilers and components, complemented by a recurring after-sales services and spare-parts business covering inspections, maintenance, retrofits and training for Danstoker and competitor installations. Customer segments are weighted toward municipal and cooperative district heating utilities and industrial manufacturers (paper, food, chemicals) across most European countries, with growing exposure to waste-to-energy operators and to data-center / energy-flexibility use cases via electric boilers. Danstoker markets through a channel-partner model (biomass partners and professional cooperation partners delivering turn-key solutions), supplemented by direct ex-works sales for large custom projects and Thermax Group channels internationally.

The company is privately held, employs 101–250 people, and reports certifications including ISO 9001, ISO 14001, EN 3834-2, and compliance with EN 12952/12953/13445, ASME, JIS, SII, EN 1993, EN 1090 and DNV-OS-C401 standards. Its executive team identified in the source data is led by Group CEO Peter Overgaard. No public financial disclosures are available.
