Dehumidify Your Industrial Units Photo by Aabher Ray

You may have frequently heard the word 'humidity,' but you might not really know what it means. Humidity is the muggy feeling that fills the air, especially when it is very hot or when it is raining. Sometimes, it makes your hair all sticky and makes you sweat, leaving you harrowed. Even clothes do not dry thoroughly and easily in such a weather condition. When people complain about humidity they are talking about relative humidity. Depending on how bad the temperature is, there is a certain amount of water vapor that the air can hold; and relative humidity is the ratio of this fixed amount to the amount of vapor present in the air. When the humidity in your house increases, it the gives the house a musty smell and leaves you feeling stuffy. Humidity attracts pests like termites, cockroaches, fleas and dust mites. At such times, you may feel the need of a dry air dehumidifier. 

The main function of a dehumidifier is to produce an excess of water that has been removed from the condensed air. This excess water is usually called condensate and has to be collected and disposed off. There are some dehumidifiers that dispose the extra water in the form of vapor. The energy efficiency of dehumidifiers varies extensively. Dehumidifiers are also used in industrial units to control the level of humidity, since certain rooms need to be kept dry to keep the goods from spoiling. This process is called as industrial dehumidification.

In industries, these can even be operated on low temperatures and in areas with very little space. It is easy if a dehumidifier has continuous water drainage and if it is self regulated. Dehumidifiers are extensively used in areas which are hot and humid. They can also be used in emergencies for dehumidification and cooling; that is, after a calamity, or during construction work, one can use this to remove excess water and to make the atmosphere stable when there is need.

The job of an industrial dehumidifier is very important in industrial dehumidification, as it reduces excess humidity. A dehumidifier has four parts- fan compressor, re-heater, compressor cooling coils and a reservoir. The reservoir is a plastic bucket to collect the condensed water and a hose pipe can be attached to dispose off the water, with the help of a pump or a drain. It is also possible to have a dehumidifier that has an automatic switch off option. In areas where there is very high humidity and it is necessary to have the dehumidifiers functioning all the time, it is possible to find a dehumidifier that has a unit with a built-in condensate pump, that pumps out the water automatically.

Many dehumidifiers have a humidistat that allows you to set your desired level of relative humidity. A humidistat is made up of two components- a sensing element and a relay amplifier. The changes in the humidity causes an electric resistance between the two alternate metal conductors present in the dehumidifier. The resistance is measured by the amplifier and it then sends a message, which in turn signals whether the dehumidifier needs to be turned off or on. This working of a dehumidifier helps in making the atmosphere in the industries, comparatively better and less humid.
