Make a drying room your next investment

In this article, we explain why we’re seeing more buildings and commercial spaces installing drying rooms, and how the right dehumidifier can help you do the same in almost any space.

When wet clothing and equipment is left to dry in a space without sufficient ventilation, moisture that removes itself from wet materials will remain in the air. This creates a humid environment that slows down the drying process, leads to condensation and creates the ideal conditions for damp and mould growth.

Mould is a major problem. As well as eating away at anything you are trying to dry, mould creates a strong musty odour and releases toxic spores that can lead to serious illness, skin irritation and breathing difficulties if inhaled. It also has a habit of finding its way into plaster and building materials, which can cause expensive or even irreparable structural damage.

With this in mind, countless buildings and commercial spaces across Europe have upgraded their facilities with a dehumidifier-powered drying room. Some of the most common examples are found in:

  • Offices

To keep moisture and damp away from working areas, wet coats and umbrellas from the daily commute need a dedicated place to dry. With the increase of people cycling to work throughout the year, many offices have turned these spaces into drying rooms to handle the humidity caused by hangers filled with wet clothing.


  • Modular buildings

For the comfort and safety of employees working on-site in the construction industry, modular buildings are often used to store clothing and protective equipment between shifts. These temporary buildings can be turned into drying rooms to make sure that kit is warm, dry and ready to use in time for the next day’s work.


  • Hotels

While hotel owners would love to promise their guests sunshine and clear blue skies, good weather can’t be guaranteed on every holiday. The next best thing is a drying room for wet coats and footwear from days out in the rain. As well as improving guest experiences, this will stop damp air from spreading through the building.

How do you turn almost any space into a drying room?

Creating an efficient drying room takes more than just installing a heater. While heat will lift moisture from clothing and equipment, in an unventilated space, this saturated air will be left to linger. As air warms up, it becomes able to hold a higher water content. When the air cools down, or when it can hold no more water at the current temperature, RH levels will reach 100% or, ‘dew point’. This is when water droplets are released and condensation forms.

A dehumidifier, on the other hand, will circulate humid air throughout a space, physically removing moisture from the air as it flows through the system. To accelerate the drying process, a high quality dehumidifier will also convert the energy taken out of the room as moisture to provide useful heat. That means faster drying and cheaper bills. In fact, the potential energy savings are huge, often achieving cost savings of 75% compared to traditional heat and ventilation energy usage.

The process

  • Damp air is drawn into the dehumidifier and across a refrigerated coil

  • The air is cooled below its dew point, condensing the water vapour

  • Latent heat energy is recovered and re-used

  • Cooled air passes across the condenser and reheated

  • The warm dry air is then returned to the room at the required humidity


Key benefits of Dantherm dehumidifiers:

  • High performance level, even in unheated rooms

  • Powerful centrifugal fan

  • Professional hot gas automatic defrost

  • Automatic hygrostat controlled dehumidification

  • Can connect to an external condensation drain or condensate pump

  • Self contained


If you need to upgrade your drying facilities, the good news is that the right dehumidification setup can help you create a drying room in virtually any part of your building.
