There are wide and varied uses for Controlled Humidity Environments spanning across the whole gamut of human activities, from manufacturing to domestic, farming to museums. We have produced an informative guide called ‘CHE an explanation’ which details how the concept works - it can be downloaded from our web site. These are some typical applications for our small dehumidifiers:


Used to keep ullage space moisture free which inhibits growth of mould, prevents caking of the product in the pipes and hoppers, and enables the product to flow freely.


Used by various fire and flood restoration companies and loss adjusters to limit costs and return premises to normal as soon as possible. Removes 0.5 - 2 kg/hr of moisture per hour depending on machine size, making it suitable for most drying applications, domestic and commercial. Also very useful for drying out newly plastered walls. The machines are portable and easy to set up making them convenient to move from job to job.

Archive Storage

This range of machines are used in small archives where valuable items need to be stored in an environment with close control of both temperature & humidity. Allows documents, video, and microfiche to be stored for many years without degradation.

Freezer Storage

Used to stop doors from freezing and prevents ice from forming on floors which prevents personnel from slipping, and fork lifts from losing control. Reduces the build up of frost on the evaporator coil and lowers running costs incurred through expensive defrost cycles.

Military Storage

For the last 30 years desiccant dehumidifiers have been used to protect valuable military equipment from corrosion and degradation, allowing aircraft, ships, tanks, weapons and ordnance to be maintained in an operational and ready state.

Food Industry - many food and confectionary businesses are realising the advantages of using desiccant dehumidification in their production process. Some of the main uses are;

Fish - by drying the surface of the fish, moisture loss during the smoking process can be prevented.


High humidity can cause problems such as chocolate blooming, stickiness in high boil products, caking of the product in hoppers and pipes and the product sticking together in the packaging process.


Low relative humidity is essential in the sugar industry to keep the product flowing freely. Sugar absorbs moisture causing it to become lumpy and hard. In this process, dry air is usually introduced into the ullage space of the storage silo.


Both temperature & humidity control are vital in the maturing stage of cheese manufacture.

Pharmaceutical Industry

Desiccant dehumidification is the best choice where cross contamination is to be prevented. Desiccant rotors are non-toxic and bacteriostatic. Some of the uses are: 


Prevents agglomeration, moisture uptake and crumbling of the product.


Many products are coated in a water based product, which has to be dried quickly to prevent moisture from affecting the product.

Gelatine Capsules

Hygroscopic materials such as gelatine need moisture protection prior to the capsule being sealed.


Low humidity is required during the packaging process to prevent effervescent tablets from dissolving and gelatine capsules from becoming sticky.

Media Storage

For the storage of sensitive video, photographic & audio media. Ongoing research means sensitive media can now be preserved for longer periods and held in temp/humid controlled vaults to provide the best and  safest storage available.

Timber Drying

Our machines can be used for the drying and storage of timber. Stage drying to prevent warping and shrinkage of the timber. CHE can equally be used to dry out buildings & historical items after flood or restoration.

Powder manufacturer: dehumidifiers can  be used to provide product stability and a suitable environment for the production and packaging of modern dishwasher & washing powders. Recent changes have been made to the packaging material, using a soluble film means less waste & safer product handling but this needs a CHE when being manufactured and packed.
