Ultra-low humidity space (-60℃DP)
to produce secondary batteries

Shinsung E&G provides our customers with a dry room that has an ultra-low humidity environment (-60℃DP) to produce secondary batteries. We have begun developing dry room technology that reduces the operating energy of industrial dehumidifiers through a technical partnership with a company specializing in desicant rotors in 2016. As a result, we have obtained a patent for a dry booth that reduces controlling costs by reducing the amount of air at a low dew point, supplied to the local dehumidification area in the dry room. We are building an optimal environment by controlling humidity perfectly with innovative air control technology, and we are achieving energy efficiency and reduced operating costs through a dry booth. We are continuously conducting technology development to establish an ultra-low humidity environment essential for the production of all-solid-state batteries, and we are actively responding to the increasing global demand for dry rooms by establishing overseas corporations.
