Dehumidifiers or fans: which drying method is best for you?

Posted on

If you have an area that needs to be dried out then you may be confused about which method of drying is best. Drying is simply the process of removing moisture from an area and there are different ways to do that. How do you decide which is the best option for you?

Using fans

Fans are really useful in speeding up the drying process as they keep air circulating. Air can hold moisture but as it cools the moisture will evaporate so moving moisture away from a wet area will help it dry faster. Fans can be used in conjunction with heaters and dehumidifiers or by themselves.

A fan is useful if you are drying an item in a warm environment as it keeps the warm air flowing passed the wet item or surface. This allows the moisture to be collected by the warm air and carried away.

If you are drying materials that can be damaged by heat then you may decide to use a fan as it will only circulate the air in the room. Equally if you don’t want to remove moisture too fast, or remove too much moisture, then a fan is a good choice.

Using dehumidifiers

Dehumidifiers remove moisture from the air and replace it with dry air which then collects more moisture and the process is repeated. Many dehumidifiers collect the water and so need emptying on a regular basis. The frequency that they need to be emptied will depend on the capacity and the amount of moisture in the room.

Dehumidifiers are not the most efficient drying method if the area is large or cannot be sealed, because they will collect the moisture from the entire room. If the room is not sealed then moist air will continue to be introduced from outside which will delay the drying process.

If you are drying a room that can be sealed or an item that can be isolated in a small room, then a dehumidifier will speed up the drying process.

If you live or work in a room with very little ventilation, then a dehumidifier can prevent the room from becoming too humid. Removing damp air from a room is important as it can reduce the risk of mould which can damage structures and be detrimental to your health.

Using heaters

Warm air holds more moisture than cold air and so using heat will speed up the drying process.

For heat drying to be most effective it is important that the moist air can be removed from the wet area, as once the air cools the moisture will condensate.

Heating can be very effective but some materials can be sensitive to heat. It may warp a material or cause it to crack or become brittle. Heating is not suitable for every situation.

Using Arxell

Arxell units can be connected to fans, heaters and dehumidifiers depending on which method is most suitable for drying your item or area. Because Arxell creates a micro-climate around or over the wet surface it enhances the effectiveness of the drying equipment.

The drying air is focussed directly on to the wet surface and Arxell is proven to dry an area up to three times faster than using just dehumidifiers or fans on their own.

Arxell also allows you to have more control over the temperature and flow of the air being circulated, so it is ideal for drying materials that are sensitive.
