Create a healthier, drier, and more energy-efficient indoor environment with Australia’s leading humidity control specialists. We design and install commercial, industrial, and residential dehumidification and heat recovery ventilation systems, purpose-built for Australian conditions.
With over a decade of experience, DEHUM delivers customised humidity control systems that eliminate moisture, prevent mould, and improve energy efficiency across residential, commercial, and industrial buildings.
Engineered for factories, warehouses, clean rooms, data centres, food processing, and manufacturing. Our systems reduce condensation, protect equipment, and maintain strict humidity levels.
Control condensation, protect building structures, and maintain comfortable indoor climates for pools, spas, and aquatic centres.
Improve indoor air quality, reduce moisture, and maintain stable humidity levels throughout your home.
We work with construction professionals, commercial operators, and homeowners to deliver reliable, long-life humidity control systems.
Every system is tailored to your building,no guesswork.
DEHUM designs, supplies and maintains industrial and commercial dehumidification systems across Australia. We specialise in Dantherm desiccant dehumidifiers for reliable humidity control in homes, warehouses, data centres, defence facilities, water-damage restoration, museums, aquatics and food manufacturing.
In cool to mild climates, or where very low RH is re (<40%), desiccant dehumidifiers outperform refrigerant types. They work from -20°C to +40°C, control humidity precisely and suit large or unheated spaces (warehouses, defence storage, museums). Refrigerant units suit warm, damp rooms where RH around 50–60% is acceptable.
Both. We specify compact units for homes, apartments, basements, wine cellars and indoor pools, plus large desiccant systems for industrial and government projects in Sydney, Melbourne, Brisbane, Perth, Adelaide and regional Australia.
We calculate moisture load from room volume, air-change rate, temperature, infiltration, process moisture and target relative humidity (RH). Share your room dimensions, use and RH target (e.g., 45% for mould prevention, 35% for archives), and our team will provide a right-sized Dantherm model, airflow and duct layout.
Keep indoor RH between 40–55%. Below 60% inhibits mould growth; ~45% is a practical target for houses, strata common areas and aged-care. For archives, galleries and museums, we often maintain 45% ±5% RH.
Yes. We deploy high-capacity dehumidifiers for rapid structural drying after summer storms and floods. Our team supports restoration contractors and councils with short-term hire, project sizing and 24/7 support.
