Precision dehumidification. Dry air, engineered worldwide. Four decades of sorption technology leadership.

DST America is the U.S. subsidiary of Seibu Giken DST AB, founded in Spånga, Sweden in 1985 and today part of Seibu Giken Co., Ltd., the Japanese manufacturer that pioneered silica gel desiccant rotor technology in 1984. DST entered the U.S. market in 2012 and now operates alongside sister companies in Poland, East Africa, and China, with representatives in more than 50 countries worldwide. The product range runs from compact desiccant dehumidifiers as small as 30 CFM up to large-scale Flexisorb systems exceeding 15,000 CFM, all built around the same sorption rotor principles the parent company was founded on. DST's units serve industries where moisture control is mission-critical — pharmaceutical dry rooms and clean rooms, lithium battery manufacturing, cold storage, grain and dry-goods storage, and general industrial process drying — with both standard and fully custom configurations for nearly any humidity challenge. Whether you're protecting a pharmaceutical production line, controlling dew point for battery safety, or keeping a warehouse free of condensation, CES is proud to represent DST America across the region, with the technical expertise to help you select, specify, and support the right dehumidification solution for every project.
