Dehumidifiers are home appliances that are used to reduce the humidity inside a house or building. <br />The reduction of excess humidity inside a house has various benefits such as reducing the number of allergens that could cause sickness and also reduces odors. <br />There are three types of dehumidifiers such as heat pump dehumidifiers, chemical absorbent dehumidifiers and ventilating dehumidifiers. <br />Heat pump dehumidifiers are the most common type of dehumidifier and are also called refrigerant dehumidifiers. <br /> A heat pump dehumidifier has a fan that draws the moist air from the room into the appliance. The air is then passed through a heat exchanger or condenser coils where the moisture from the air is turned into a liquid which is then drained out and the dry air is sent back into the room. <br />Chemical absorbent dehumidifiers use a desiccant absorbent like silica gel to absorb the moisture which is then sent out through a vent. <br />This type of dehumidifier is commonly used in extremely hot conditions or for industrial applications. <br />The most inexpensive type of dehumidifier is the ventilating dehumidifier which pumps the moist air out through a vent. <br />Visit yellowpages-uae.com to know more about Dehumidifiers Products Suppliers in Dubai i.e. at http://www.yellowpages-uae.com/uae/dubai/dehumidifiers
