JTK Power Oy

What JTK Power Oy does

JTK Power Oy is a Finnish industrial manufacturer of custom-designed steel solutions, operating as part of the Koncentra Group with three production entities in Vöyri (Finland, headquarters), Suzhou (China, established 2012), and Estonia (acquired 2018 via JTK Power Finmec). The company's revenue is anchored in three product lines: (1) silencer solutions for marine engines, power plants and process industry, including exhaust gas, flue gas, air intake, out-blow silencers and combined silencer-chimney structures; (2) civil defense shelter equipment — Eurofins-certified steel doors up to 3.9m x 3.6m, hatches, wall sleeves and S1-classified ventilation units; and (3) project solutions encompassing SCR units, exhaust gas modules, turnkey projects and custom welded structures up to 30 tonnes per piece. Supporting services include mechanical and acoustical engineering (FAT/SAT testing, noise and vibration measurements), and cobot-assisted precision machining of axially symmetrical components such as valve seat inserts. Manufacturing relies on Yaskawa Motoman robotic welding, ESAB submerged arc welding towers, Universal Robots collaborative robots, and comprehensive NDT and acoustic testing.

The business operates as a B2B engineered-to-order enterprise with a direct sales team of product and sales managers, quote-based pricing tied to customer specifications, and multi-year project cycles tied to shipbuilding and power plant construction. Approximately 70% of group revenue (~28 MEUR) is exported, with products deployed in 160 countries and a named customer roster that includes Wärtsilä (marine engines, catalyst frames, SCR units), Eckerö Line and Wasaline (shipping), Rauma Marine Constructions (shipyard), and Kivisydän/Oulun Pysäköinti Oy (civil defense). The commercial motion combines direct enterprise sales, long-standing OEM partnerships, industry-event presence (POWERGEN), and annual customer-site visits.

The company is positioning for sustainability-led differentiation: in September 2025 it delivered the world's first low-carbon marine engine silencer to Wärtsilä using SSAB Zero™ fossil-free steel (carbon footprint ~50% smaller), and the Koncentra Board approved a 20% expansion of Vöyri production capacity in April 2026 for completion by year-end. Civil defense shelter products carry a 50-year design lifespan and are expanding from Finland into Sweden. The group employs ~157 people across Finland and China, with a new Monitor ERP system implemented in November 2025 to support scaling operations.
