DEHUMIDIFIERS
The challengeAtmospheric air contains moisture which is a problem to materials and manufacturing processes.
CALOREX DEHUMIDIFIERS
Protect your environment
Even when you cannot see it, moisture in the form of water vapour is all around us, held in suspension in the air. The relative humidity of the air in many cases determines the extent of corrosion of certain materials, the speed at which moulds develop and the rate of increase of bacteria that cause decay. Most materials and goods are best stored under cool dry conditions.
A false economy
Traditionally the problem was disguised by the use of heat or ventilation. This process is exceptionally energy inefficient and reliant on introducing outside air that is generally not suitable unless expensively heated. Drying by traditional heating involves continuously warming a stream of outside air on a constant ‘in and out’ cycle.

Relative humidity in %
With an RH of over 60% the rate of corrosion on steel rises rapidly. At an RH of approximately 50%, virtually no
corrosion occurs.
Relative humidity
Relative humidity (RH) is the expression used to define how much water vapour can be held in the air at a given temperature as a percentage of what it could contain at saturation (100% RH). That is when the relative humidity reaches the level at which air can hold no more moisture. The maximum amount can vary according to its temperature – warmer air is capable of holding more moisture than colder air.
Calorex dehumidifiers are ideal for:
�Cold stores
�Utility buildings
�Computer rooms
�Switching and power stations
�Electronics production
�Pharmaceutical production
�Manufacturing areas
�Process drying
�Bottling and food plants
�Archives, museums and libraries
�Sports halls
�Wet clothes drying rooms
�Ice rinks
�Boiler rooms
�Ship building and offshore
�Underground rooms
�Drying flooded areas or new buildings
�Preservation of buildings, plant, ships, drilling platforms and turbines
�Applying industrial coatings
�Maintaining bridges and locks
Heating and ventilation is extremely energy inefficient and expensive. Luckily a solution does exist to make the air drier without heating – Calorex dehumidification
Key benefits of a Calorex dehumidifier:
�Flexible design for simple use and installation
�Energy efficient
�Low temperature operation
�Available with air heating option
�Automatic operation
�Quality construction
�Optional features
�Heat recovery to air
A better way
Dehumidification is much more sophisticated than heating. It recirculates the same air and physically removes moisture from it. This alleviates the need to continuously reheat incoming air. Not only that, a dehumidifier will cleverly convert energy taken out of the room as moisture (latent energy), to create ‘sensible energy’ that can be used to heat the room, accelerating the drying process.
The solutionThe Calorex answer to this problem is its wide range of dehumidifiers suitable for every environment from warehouses and sub-stations to museums and garages.

How a Calorex dehumidifier works
The process of dehumidification involves moisture-laden air being drawn into a dehumidifier where the air passes across a refrigerated coil. The air is rapidly cooled below its dew point, condensing the water vapour and recovering its latent heat energy for re-use. The cooled air is then passed across the condenser where it is reheated and returned to the served area at the required lower relative humidity.
