Langh Tech Oy Ab operates as a specialized technology developer within the Finnish maritime cluster, focusing on environmental compliance systems for the global shipping industry. Established as a distinct entity to commercialize clean-tech solutions, it shares its heritage with a long-standing family-owned shipping company. The organization’s roots are deeply embedded in practical ship ownership, arising from a direct need to address tightening international emission regulations in the early 2010s. Rather than originating solely as an equipment manufacturer, the company evolved when its affiliated shipping arm sought efficient methods to clean exhaust gases on its own commercial vessels. This operational background allows the firm to approach engineering challenges from the perspective of a ship operator, emphasizing reliability, ease of maintenance, and space efficiency on board diverse vessel types.
The core of the company’s operations revolves around designing systems that mitigate the environmental impact of marine transport. Its engineering teams focus heavily on exhaust gas cleaning technology, commonly referred to as scrubbers, which remove sulfur oxides from ship emissions. Beyond air pollution control, the firm has significantly expanded its capabilities into complex water treatment. The company designs closed-loop water treatment units that purify the process water used in scrubbing, ensuring that discharge meets strict environmental standards. These water treatment principles have also been adapted for other maritime applications, including ballast water management. A distinguishing feature of the company’s operational model is its ability to test and refine prototypes on the trading vessels of its sister company, ensuring that equipment functionality is verified under actual sea conditions before wider market release.
Headquartered in the Piikkiö area of Finland, Langh Tech serves a global client base ranging from container ships and tankers to the passenger and cruise sectors. The company supplies solutions for both retrofitting existing fleets and outfitting newbuilds at shipyards throughout Europe and Asia. As the maritime sector transitions toward decarbonization, the firm has broadened its research and development to include carbon capture capabilities, aiming to address future regulatory landscapes regarding greenhouse gases. By retaining control over design, manufacturing, and commissioning, the organization maintains a comprehensive role in the supply chain, supporting shipowners in navigating complex environmental mandates with practical, sea-proven engineering.
