Engineering firm Rörkraft

What Engineering firm Rörkraft does

Rörkraft is a Swedish multi-discipline engineering consultancy founded in 1998 and headquartered in Lund, with regional offices in Karlshamn and Stockholm (Bromma). The firm delivers engineering services across process engineering, piping and plant design, automation and industrial IT, electrical construction, structural engineering, and strength calculations, plus in-house laser scanning and a mobile VR studio for digital-twin workflows in both greenfield and brownfield environments. Its principal proprietary product is PipeCalc, a Windows-based calculation program for dimensioning pipes and pipe components to the SS-EN13480 European pressure-equipment standard, sold as perpetual single-user (SEK 13,480) or network licenses. Other service lines include energy efficiency optimization, project leadership, and construction engineering using industry-standard tools such as Ansys, Caesar II, EPLAN, and AutoCAD Electrical.

The company serves Swedish municipalities, industrial enterprises, and the defense sector through direct B2B project engagements covering the full lifecycle from feasibility and design through construction documentation, commissioning, and material supply. Revenue is generated primarily through professional services fees on quoted project work, supplemented by one-time PipeCalc software licensing. Five customer segments anchor the book: clean water and wastewater infrastructure (the largest, aligned with a SEK 560 billion Swedish modernization pipeline through 2040), the energy transition, sustainable industries, defense (as an approved supplier), and research and development. The firm employs approximately 80 engineers and reports SEK 122 million in revenue with an 11% EBITA margin.

As of February 2026, Rörkraft operates as a wholly-owned subsidiary of Rejlers, a Nasdaq Stockholm-listed engineering consultancy, retaining its own brand within Rejlers' Industry division. Founder Clas Wollberg remains CEO of Rörkraft Syd AB, with Håkan Wessel leading the group as CEO and Chairman. The company's competitive position rests on multi-discipline one-roof delivery, 25 years of accumulated domain specialization in Swedish societal infrastructure, and a junior-engineer development pipeline recruited directly from university partners.
