Company Introduction
Doojin Cryogenic Business Division
Since its establishment in 1994, Doojin Co., Ltd.’s Cryogenic Business Division has been a leading company in the cryogenic industry, specializing in the domestic manufacturing of cryogenic storage tanks, cryogenic vessels, vacuum-insulated piping, Dewars, and LNG supply systems, as well as the supply of products from Chart and MVE.
In the late 1990s, we successfully developed Korea’s first cryogenic storage vessels and vacuum-insulated piping technologies. Based on these advanced technologies and accumulated expertise, we provide comprehensive Cryogenic System Solutions, covering the entire process from engineering and manufacturing to installation, commissioning, and regulatory approval.
In particular, our vacuum-insulated piping technology has become a market
