How does a desiccant dehumidifier work?

Dehumidifiers are devices used to reduce the relative humidity of the air. Although they are available in many varieties and technologies, a desiccant dehumidifier can be a relevant option as it is an economical, reliable and effective product.

Operation of a desiccant dehumidifier

The main component of a desiccant dehumidifier is silica gel, which absorbs water vapour from the atmosphere. This substance consumes thermal energy to absorb moisture from the air, thereby increasing its own water vapour content. This vapour must be removed before the gel can be used again to control humidity.

Desiccant dehumidifiers consist of four components:

  • The drying rack Silica gel: as the name suggests, this component of the dehumidifier contains silica gel.
  • The fan The fan draws in the air that is finally passed over the dehumidifier.
  • Heating the heater helps to heat the indoor air
  • The fan for drying This part of the appliance allows the water vapour to escape from the dehumidifier so that it can be used again to absorb moisture.

The desiccant dehumidifier has a drip tray that can be connected to the garden hose or plumbing system of the house. This system allows water to be expelled from the unit. Most bathroom dehumidifiers are equipped with a shut-off device that stops the appliance if the water in the drip tray is not drained. This prevents the appliance from being damaged by excess water.

What to do with the collected water?

The water collected in the tank is not suitable for drinking or for gardening edible plants, as it may contain heavy metals such as lead and copper which are particularly harmful to health.

In addition, the water accumulated in the collection tanks usually remains there for some time. It is therefore a real nest of microbes containing numerous pathogens capable of causing infection if the water is consumed

Why use a desiccant dehumidifier in your home?

When the relative humidity of the atmosphere exceeds 30 to 50 %, there is a strong tendency for microbial accumulation. These fungal spores lead to a mould infestation in dark areas of the house. Another reason to use a dehumidifier is to avoid water vapour condensation which can be annoying at night.

On the other hand, high relative humidity means that you will necessarily have to use the tumble dryer for all types of clothes. As you cannot do this with woollen garments, you may find it increasingly difficult to air-dry garments with high atmospheric humidity.

Dehumidifiers with desiccation s are used to control humidity and all associated problems, providing a clean and hygienic environment in your home. These devices also have many applications in industrial environments that require temperature and humidity control.

Desiccant dehumidifiers are commonly used in pharmaceutical companies, power plants, drying plants for hygroscopic materials, breweries, stadiums, etc.
