Industrial dehumidifier
A locally developed industrial dehumidifier, designed to reduce reliance on imported equipment and to be serviced and customised close to where it runs.
Humidity control. Engineered at home.
Many processes need air drier than ordinary air conditioning can deliver: hygroscopic powders, gelatin capsules, effervescent products, lithium processing and cold stores among them. A desiccant rotor dehumidifier dries air by adsorption rather than condensation, so it keeps working at low dew points and low temperatures where cooling coils cannot.

Operating principle
Process air is filtered
Humid process air is drawn in through a filter that protects the desiccant rotor from dust.
The rotor adsorbs moisture
Process air passes through the larger sector of the slowly turning desiccant rotor. Water vapour is adsorbed onto the desiccant and dry air leaves the rotor.
Dry air is delivered
The process fan supplies the dry air to the room or process. Adsorption releases heat, so dry air leaves slightly warmer; a post-cooling coil can be added where temperature matters.
Reactivation air is heated
A separate, smaller stream of air is filtered and heated before entering the rotor’s reactivation sector, flowing in the opposite direction to the process air.
Moisture is exhausted
The hot reactivation air drives moisture out of the desiccant. The reactivation fan exhausts this warm, wet air outdoors, and the dried rotor turns back into the process sector.
