The comfort and health of workers is a key factor in industrial productivity. So is equipment and process reliability and consistency. All of these are dependent on working and operating environments that are free from excessive ambient moisture.

Dehumidifiers are widely used in industrial applications, including food processing, powder blending and mixing, laboratories and computer rooms, metalizing houses, printing rooms, water treatment plants and silk screening operations. They help to prevent material degradation and equipment damage that happen through clogging or sticking (due to moisture absorption), mould and bacteria contamination, or corrosion and oxidation. Dry and clean air helps to maximize process uptime, worker morale and productivity, and hassle-free maintenance.

Several dehumidification technologies are available. An engineer will consider the environment and application type before choosing which one to use. The two main operating principles in use are refrigeration and desiccation. Refrigerative systems cool air so that water vapour condenses into liquid, which can then be drained away or removed. Desiccant systems use an adsorbent or absorbent chemical from which water can then be removed, typically by heating. The nature of these two respective processes entail that refrigerative systems tend to be more effective in warm (above 20 °C) environments and desiccant systems in cold (below 20 °C) ones.

Advances in technology and wide recognition of the importance of climate control have meant that portable units are now often found in industrial environments. It is essential that the unit is correctly sized for the space. Wrongly sized units can result either in poor humidity control or in energy inefficiency.
