DKME is an Ulsan-based chemical equipment manufacturer founded in 1981 and listed on the KOSPI in 1989, formerly known as Daekyung Machinery Technology and later KIB Plug Energy before adopting its current name in May 2025.
Its core business is the chemical equipment segment, producing heat exchangers, pressure vessels, and storage tanks, alongside an energy plant segment that makes industrial boilers, co-generation power boilers, and auxiliary boilers.
Building on roughly four decades of operating history and external credibility, the company has historically derived about 85% of its revenue from exports.
Its main customers are global EPC (engineering, procurement, and construction) firms, and in June 2026 it signed an equipment supply contract with France-based EPC firm TECHNIP for a Qatar LNG plant expansion project. Domestically it competes with other heat-exchanger and chemical-equipment makers such as SNT Energy.
The company had been placed under an exchange listing-eligibility review and suspended from trading for an extended period due to issues tied to former management, and control of the Ulsan-based chemical equipment specialist, which had been halted from trading for over a year amid embezzlement allegations against management, passed to a consortium of industrial hydrogen producer Deokyang Energen and industrial boiler maker Wolf.
During the ownership-change process, an earlier prospective acquirer, Enerjin, stepped aside, and the Deokyang Energen–Wolf consortium emerged as the final buyer, under a structure combining a controlling-stake purchase with a capital increase, in which all 52,862,216 common shares were transferred under a contract valued at roughly KRW 32.7 billion.
