Introduction To Dehumidifiers

1. Introduction To Dehumidifiers In this PPT you will get to know about dehumidifiers, their applications and their types.

2. Dehumidifiers • Air Dehumidifiers are useful for decreasing humidity levels of homes, offices, museums, warehouses, cold rooms etc. The operational principle is by absorbing the moisture from the air and thus reducing the humidity levels. We are supplying air dehumidifiers manufactured by Trotec, Germany. They manufacture numerous types of dehumidifiers for industrial, commercial and residential applications. These are typically used for hotels, swimming pools, offices, warehouses, cold rooms, apartments, villa etc.

3. Applications of Air Dehumidifiers • Typical applications are: • Maintain the humidity inside cold rooms, walk in chillers etc. which are used for storage of medicines, vaccines etc. Such rooms should maintain a maximum humidity of 55-60% RH. There are low-temperature dehumidifiers for the ambient temperature near and below 0°C. • Maintain humidity during storage of fruits and vegetables inside warehouses and walk in freezers. If the humidity goes above prescribed limits, the life of such items will be reduced drastically. • Maintain humidity inside warehouses storing medicines, electronic items etc.

4. •Libraries, museums, document archives etc. which should have low humidity levels. High humidity will cause the formation of the mold thus destroying artifacts, books, paintings etc. •Reduce humidity in basements, car parks etc. •For residential rooms, hospital rooms, and offices the humidity has to be under comfortable limits. For such applications, portable silent dehumidifiers are used. •Reduce humidity inside indoor swimming pools. Swimming pools produce a huge amount of moisture which will cause huge damage to adjacent walls and rooms. •Industrial and commercial dehumidifiers for various applications in industries for maintaining humidity. •Interior Dehumidifiers combined with an air purifier for purifying air along with reducing humidity.

5. Types of Dehumidifiers A. Desiccant dehumidifiers Desiccant type models use silica gel or similar absorbents for absorbing the atmospheric moisture. These are available in stationary and mobile versions. Industrial Desiccant dehumidifiers are available up to a capacity of 58 kg/hour. These models are also called adsorption dehumidifiers.

6. B. Condensation dehumidifiers These type of air dehumidifiers absorb moisture from the air by means of condensation and convert the same into water. This water is drained out of the room through a hose. Also, we can connect a small water pump to pump out the water. Mobile condensation type commercial dehumidifiers are available with a capacity ranging from 32 liter/24 hours to 150 liter/24 hours.

7. C. Basement dehumidifiers Basement dehumidifiers are for usage in the basement of buildings for reducing humidity. The basement of buildings tends to have a higher humidity due to problems of water logging. Also, de humidifiershumid air is heavy and hence settles down in the basements. Desiccant type or Conddehumidifierscan be used for normal capacity requirements of basement dehumidifiers.

8. D. Dehumidifiers for increasing humidity Humidifiers are used to increase the humidity of rooms, warehouses etc. as per the desired levels of humidity. This works by means of evaporation and hence also are known as evaporation humidifiers. Trotec, Germany manufactures humidifiers of various capacities from portable models to stationary models. The applications include keeping right humidity for storage of vegetables, fruits dried fruits etc. which need to be stored at a certain humidity.
