What Justsen Energiteknik does

Justsen Energiteknik A/S is a privately held Danish original equipment manufacturer founded in 1959 that designs, manufactures, and services biomass-fueled boiler systems spanning 300 kW to 30 MW. Its core product portfolio covers hot water boilers, saturated steam boilers, superheated steam boilers for combined heat and power (CHP), Organic Rankine Cycle (ORC) boilers, and WID/IED-compliant boilers that combust contaminated wood waste and other waste-derived biomass, complemented by a standardized ARGUS cost-effective line and OEM system elements for fuel handling. The company differentiates through proprietary bag filter flue-gas cleaning technology, deep engineering know-how built over six decades, and bespoke configurations tailored to fuel type, emissions standards, automation, and process requirements.

Justsen monetizes through three revenue streams: one-time project sales of custom-engineered boiler systems (contract values typically in the millions of DKK or AUD, e.g., ~25M DKK for the Midtlangeland district heating project and ~$10M AUD for the MSM Milling canola plant), recurring after-sales service agreements (Basic Support, Service Plus, 10-Year Extended Warranty, Remote Alarm Service, Emergency Box spare parts), and spare parts supply. Go-to-market combines a curated network of local technical partners in selected geographies (KG Systems for greenhouses, Tjaereborg Industri in Denmark, Latvijas Energoceltnieks in Latvia, New Heat Group in Lithuania) with wholly-owned subsidiaries Justsen Pacific Pty Ltd (Sydney, established 2017) for Asia Pacific and Euro Therm A/S (acquired 2019) for Denmark. The company serves enterprise customers across at least eight verticals including district heating, CHP, greenhouses, textile, food and beverage, biogas, and wood processing, with reference customers such as Neame Lea / Bridge Farm Group, Rigas energija, Gildan, MSM Milling, Grøngas Vra, Dovista, and Kangshifu.

Ownership remains with the founding family — Claus Justsen is identified as Owner — with Anders Jacobsen serving as CEO. Operating geographies span Europe (UK, Denmark, Latvia, Lithuania), North America (Honduras), and Asia Pacific (Australia, China). No external funding, parent company, or public listing is disclosed.
