DongHwa Entec

What DongHwa Entec does

DongHwa Entec (주식회사 동화엔텍) is a Busan-headquartered, privately held Korean engineering company founded in 1980 that designs and manufactures compact heat exchangers, compressors, and integrated fuel supply systems for marine, power generation, and hydrogen infrastructure applications. Its core technology platform comprises PCHE (Printed Circuit Heat Exchanger) and PFHE (Brazed Aluminum Plate Fin Heat Exchanger) units, which enable handling of cryogenic and ultra-high-pressure fluids such as LNG at -163°C, liquid hydrogen at -253°C, and ammonia — capabilities that have earned six Korean World Class Product designations. The company holds World No. 1 market share globally in Fuel Gas Supply Systems (FGSS) for LNG-fueled vessels and BOG Compressors (via subsidiary DongHwa Newteq), with the BOG Compressor equipping over 95% of LNG-fueled vessels built in Korea. It also commands a 70-80% domestic Korean share in hydrogen refueling pre-coolers, with 180+ units deployed.

The company transitioned around 2014 from single-component manufacturing to integrated system packages, a shift confirmed in 2023 when system product sales surpassed single-product sales for the first time. DongHwa Entec operates through wholly-owned subsidiaries: DongHwa Newteq (BOG and ammonia compressors, est. 2007), DongHwa Hightech (hydrogen compression via ionic liquid technology, est. 2023), Euntae Industry (Shanghai sales office, 2008), and Jiangsu Donghua (China manufacturing, Jiangsu Province). Revenue derives primarily from direct enterprise sales of system packages to Korean Big 3 shipbuilders (Hyundai HI, Samsung HI, DSME), Chinese shipyards (NTS, GSI/CSSC, Yangzijiang, CSE), ship operators (Eastern Pacific Shipping, KARMOL, Haewool, Korea Gas Shipping), and hydrogen refueling infrastructure operators. The company maintains in-house R&D (Energy Environment Technology Research Institute in Busan), 2,192 days of zero-accident manufacturing at the Nokshan facility, and active participation in global exhibitions (KORMARINE, POSIDONIA, H2 MEET, MARINTEC CHINA). Recent strategic moves include NH3 LFSS AIP certification from Korean Register, hydrogen liquefaction development with GS Construction, and EMS development with Hanwha Systems, positioning the company across LNG, ammonia, and hydrogen value chains.
