Efficiency by Design
Established (UK) in 1996, we aim to promote the same core business values that make Seibu Giken DST a world leader in desiccant dehumidifier technology.
Humidity Control Systems is a member of the Seibu Giken DST worldwide group of companies; specialists in design and manufacture of industrial desiccant dehumidifiers and bespoke dehumidification systems.
In 1984, Seibu Giken developed and commercialised the world’s first activated silica-gel honeycomb rotor, the primary component of a desiccant dehumidifier.
We continue to embrace the same principles that our parent company was founded upon; providing efficient, exceptionally well-engineered dehumidifiers of superior quality. Continuous investment in research and development has ensured our desiccant rotor remains the most technically advanced worldwide.
We are confident that we will not only meet, but will exceed your performance expectations.
