JNK GLOBAL LTD

What JNK GLOBAL LTD does

JNK Global Ltd (제이엔케이글로벌, formerly JNK Heaters) is a South Korean industrial equipment manufacturer headquartered in Seongnam-si, Gyeonggi-do, that designs and supplies two core product lines. The first is custom process fired heaters engineered to the topographic features and operational requirements of each customer's plant, used in industrial heating applications. The second is hydrogen refueling station infrastructure, offered as both off-site refueling facilities for hydrogen fuel cell vehicles and on-site hydrogen production facilities based on CNG and LPG reforming, with the company explicitly positioning the on-site hydrogen output for mobility as well as semiconductor, LCD, steel, and chemical industry applications.

The business operates on a B2B project-based equipment sale and installation model, with revenue generated primarily through one-time licensing/sale of customized facilities rather than recurring contracts. Go-to-market is direct enterprise field sales, supported by a bilingual (Korean/English) corporate website with a customer inquiry form at the bottom of the funnel. Pricing is not publicly disclosed and is handled through custom project quotations. The company has been listed on KOSDAQ since at least 2016, has been active through at least 28 fiscal periods (2025), and serves customers primarily within the Gyeonggi Province region of South Korea with no disclosed international geographic footprint.

Strategically, the company has built up its hydrogen capability through a decade of government-funded R&D participation, including KETEP (2013-2014), KATECH (2016-2021), and a five-firm consortium with Puritech, KIER, Yonsei University, and Gongju University (2017-2020), and holds a Class-A voting membership in H2Korea, the national hydrogen industry association. The 2025 rebranding from JNK Heaters to JNK GLOBAL reflects a deliberate repositioning from a single-product heater vendor to a multi-product industrial infrastructure and hydrogen player.
