Seibu Giken DST

What Seibu Giken DST does

Seibu Giken DST AB is a Swedish manufacturer of sorption (desiccant) dehumidifiers, founded in 1985 and headquartered in Spånga, Sweden. The company designs and assembles a comprehensive product range spanning portable units (CONSORB CS-5) to large industrial systems with rotors up to Ø 4m, under brands including CONSORB, RECUSORB, AQUASORB, FLEXISORB, and ECONOSORB. Its core technology leverages proprietary D-MAX silica gel rotors manufactured by parent company Seibu Giken Co., Ltd. in Japan, enabling moisture removal effective at sub-zero temperatures and ultra-low dewpoints down to -60°Cdp, differentiating it from refrigerant-based dehumidifiers that lose effectiveness below 5°C.

The firm operates as a wholly-owned subsidiary of Seibu Giken Co., Ltd. (Japan) since 1993, with direct manufacturing and sales subsidiaries in China (since 2010, with factory in Changshu), USA and Poland (both 2014), and Kenya (2018). It serves industrial and commercial customers across automotive (Volvo, Volkswagen, Honda), food and beverage (Nestlé, Heineken, Tetra Pak), pharmaceutical (AstraZeneca), electronics (Samsung, Sony), energy (Vattenfall), defense (Saab), and infrastructure (Stockholms Stad) sectors, with documented relationships spanning 16+ years at major sites. Revenue is generated through one-time equipment sales, accessories, and recurring service/maintenance contracts, with quote-based pricing set by a 50+ country representative network. The company also distributes parent-produced VOC zeolite rotor concentrators and heat wheels in Europe under a contractual sales partnership, extending its addressable market into adjacent air-treatment categories.
