What KROSYS, Inc. does
KROSYS, Inc. is a privately held Korean marine equipment and water treatment company founded in 1984 (originally as Kyung Chang Inc.) and headquartered in Busan. The company operates through two product divisions: WATER, anchored by reverse osmosis (RO) desalination technology with 30+ years of specialization, and MARINE, which covers ship stabilization and propulsion equipment. Its core WATER products include Shipboard Fresh Water Generators (FWG) for naval and commercial vessels, Mobile Water Purification Systems (MWPS) for emergency and island water supply, and RO Desalination Plants with capacities up to 4,800 tons per day for offshore platforms. MARINE products include Waterjet Propulsion Systems produced under Marine Jet Power (MJP) license, Anti-Rolling Tanks (ART, acquired from Peace Engineering in 2020), and Fin Stabilizers (acquired from Pacmar Inc. in 1999), distributed alongside the Evoqua SeaCURE Ballast Water Management System under a Korean franchise.
KROSYS sells through direct enterprise field sales into Korean defense procurement (Navy, Coast Guard, DAPA) and major Korean shipyards (Hyundai Heavy Industries, Samsung Heavy Industries, Hanjin Heavy, Hyundai Mipo Dockyard), with international reach into Southeast Asian navies and offshore energy customers such as Shell's Prelude FLNG. Revenue mechanics are dominated by one-time capital equipment sales priced via quote-based multi-year contracts, supplemented by professional services including maintenance, technical exchange programs, and offshore engineering services for FLNG and offshore platform clients.
The customer base is concentrated in the Korean defense and shipbuilding ecosystem, with anchor relationships such as waterjets supplied for 8+ Korean Navy PKX-B vessels and 4 JLOTS vessels delivered in 2024. Marketing and lead generation rely heavily on defense and maritime trade shows (INDO DEFENCE 2024, MADEX 2025, KORMARINE, Korea Ocean Expo) rather than digital channels. The company is founder/family-led (Park Jung-gyu as Chairman and Park Sang-don as President since January 2022) with a wholly owned operating subsidiary, Krosys Entech Inc., established in 2015 for ocean plant and water treatment engineering.
