Frequently Asked Questions
It draws in ambient air, dries it through a desiccant bed and delivers the dry air to the space in a single pass, without recirculating. This makes it ideal for large or semi-enclosed areas.
The retractable hood provides flexible coverage over large equipment, machinery or work zones, so you can dehumidify locally without building a permanent enclosure.
Open loop suits large, temporary or semi-enclosed areas and equipment protection during maintenance. Closed loop suits sealed, air-conditioned rooms that need tightly controlled humidity.
A dew point of –20°C to –40°C depending on the application and airflow, which is enough to stop condensation, corrosion and rust.
Power plant and turbine maintenance, shipbuilding and marine work, equipment storage, paint booths, and preservation during industrial shutdowns and turnarounds.
Yes. With no heater load it is energy-efficient and, importantly, it does not add heat to the working area the way heated systems do.
It uses a modular, portable construction so it can be deployed and relocated easily between zones or projects.
Sizing is based on the space volume, the target humidity or dew point and the layout to be covered. Each system is custom-designed to those requirements.
