Dehumidifiers

The Problem

Excessively humid indoor air

If the relative humidity is above 60%, the indoor air is classed as too humid. Such a high level can promote the growth of mould and put both human and the environment at risk. If the humidity is too high, it can pose a risk to allergy sufferers in particular.

Measure humidity? We explain how it works.

Basement 

If your basement is too humid, there is a risk of any furniture or possessions stored within it being damaged or completely ruined. Mould can form and spread quickly in such conditions. But it’s not only your possessions that are at risk: spending a lot of time in a basement where there is mould can also lead to health problems. The same risk is also present in storerooms, summerhouses, hobby rooms, etc.

Laundry room 

The more humid the air, the longer washing will take to dry. In addition, the drying room will be occupied for longer and it may be a while before the next load can be hung out.

New buildings 

New buildings are often occupied as soon as construction is completed. Too little time is allowed for the building – and especially the walls – to dry out. That is why often, the humidity can remain too high in every room for the first few years. The occupants, furniture, musical instruments, paintings and textiles are permanently exposed to damp air which can cause damage.

Homes 

Over a long period of time, we often don’t notice that a home is too humid. As with new buildings, furniture, textiles and musical instruments made from wood can absorb the humidity which can cause damage. Mould can form which can present a risk to the people and animals living in the home.

The Cause

Development of excessive humidity

The moisture in the air increases when temperatures are high. That is because warm air can absorb more water vapour. A room is regarded as being too humid if the relative humidity value (proportion of water vapour in the air) is permanently above 60%.

Condensation / Compressor dehumidifier 

A surface in the device is cooled by means of a compressor. The warm humid air is passed across this surface and as a result of this cooling, the excess water vapour in the air is turned into water droplets which remain on the surface and fall into a collecting tank. The warmer and damper the air, the better these devices perform.

Peltier dehumidifier 

In the same way as in the compressor dehumidifier, the air is cooled and dehumidified when it passes over a cold surface. As this process is carried out using an electrical Peltier element, this type of dehumidifier is not ideal for whole houses as the level of performance is relatively low.

Adsorption dehumidifier 

Water-binding material draws the humid air from the water. The lower the temperature, the more efficiently these devices perform, making them ideal for use in basements.

Granulate dehumidifier 

A passive device which does not require a power supply. This device is based on the effect of water binding which is achieved by means of special salts. However its level of efficiency is very low, making it unsuitable for homes where the humidity is high.

The Solution

Dry out the air with a dehumidifier

If measures such as ventilating your home when the temperature drops, leaving the fan on in the bathroom after a shower, not drying washing indoors, etc. don’t help, it’s time to take action. The best solution is a dehumidifier. A mobile device that can be moved from room to room is preferable – like the reliable devices from Stadler Form.
