Excessive moisture and humidity can be a big problem in many environments, and it is vital organisations have the right solutions to keep their indoor climates under control. Here we outline how commercial dehumidifiers tackle these issues and which unit is the right fit for your situation.
In a wide range of circumstances, high humidity levels can cause a great deal of harm.
From encouraging the growth of mould, mildew and rust, to allowing flood damage to eat away at crucial building materials, failing to keep humidity under control can pose a real threat to people, buildings, products and more.
Effective dehumidification ensures that environments are kept within a healthy humidity range and that moisture is removed from unwanted areas. With the right climate solutions in place, companies go a long way towards guaranteeing that locations are healthy, safe and comfortable, and that items inside are protected from the risk of water damage.
However, with a wide choice of commercial dehumidifiers on the market, you may be struggling to find the best one for your needs. Below we discuss how to select the ideal option for your purposes.
What is a commercial dehumidifier?
A commercial or industrial dehumidifier is one specifically designed to manage the humidity levels in a large, commercial space, or to support professional activities such as construction work or water damage restoration.
When searching for ‘dehumidifiers’ online, you might immediately be presented with smaller, domestic versions. While these may be perfectly suited to improve the air quality and remove moisture in rooms around the home, these will not fulfil the far greater demands of commercial applications.
Could you use an electric heater to fulfil the same role?
While a heater can help pull moisture out of water-damaged materials, that water will then remain in the atmosphere. When it hits a cold surface, it will condense and you are back to square one. A dehumidifier captures moisture in the air, meaning that there is no risk of it causing further harm.
In addition, the energy cost of an electric heater can run very high, especially if you are running it as consistently as you would a commercial dehumidifier. By contrast, Aerial dehumidifiers reuse the latent heat energy generated during the dehumidification process. This is then used to reheat the cool air passing through it, helping maintain the temperature within the area.
What are the types of commercial dehumidifiers?
Commercial dehumidifiers primarily fall into two categories: condense dehumidifiers and adsorption dehumidifiers.
Also known as refrigerant dehumidifiers, condense units draw in humid air across refrigerated coils. This rapidly cools the air below its dew point temperature – condensation occurs and the unit collects the water removed from the air.
The cooled air then passes across a condenser, where it is reheated and returned to the room as dryer, warm air at the required humidity.
Also known as desiccant dehumidifiers, adsorption units draw humid air through a slowly rotating, water-trapping rotor, often made from silica gel. This material attracts the moisture, removing it from the air stream.
Once past the rotor, part of the air is discharged as dry air, while another part regenerates the rotor. Wet air is then exhausted to the atmosphere through a duct.
Which is the right choice for my needs?
Both systems can capably control the humidity in a wide variety of commercial environments. However, there are some notable differences that can help you determine which approach will be better suited in your circumstances:
Fundamentally, across a wide range of temperatures and humidity levels, a condense solution is perfectly suitable. It is often the most cost-efficient option, and can capably keep the humidity as low as 40% RH with no impact on performance or efficiency.
However, in situations where the temperatures are notably colder, such as waterworks or cold storage areas, or when you need to keep items in specific, extremely dry conditions, an adsorption dehumidifier is essential.
Furthermore, adsorption units are reliable water damage restoration dehumidifiers, as using a side-channel blower or turbine, they can target water trapped within building cavities. Unlike condense units, which circulate all air within an area, this means dry air can be channelled to exactly where it is required.
In summary, the right choice between these two options will be a balance of what is technically required against your available budget.
Choosing the right commercial dehumidifier for your circumstances
Now you hopefully have a stronger understanding of the positive impact of commercial dehumidifiers and how to decide between a condense and adsorption solution, here we provide our recommended dehumidifiers in four specific circumstances.
For construction and water damage restoration
Whether it is speeding up the drying of screed, plaster and paint, or protecting hygroscopic building materials like wood from water damage, commercial dehumidifiers play a critical role in making conditions on construction sites safer, more efficient and more comfortable for all involved.
Furthermore, a powerful drying solution is vital in restoring rooms and buildings affected by water and flood damage, ensuring that the building structure does not weaken over time, dangerous mould does not develop, and as many items can be recovered as possible.
Our recommendation: ASE 300
Due to its high performance at low temperatures and its heavy-duty yet lightweight build, the ASE 300 can deliver fast results in all kinds of construction and emergency situations, minimising the long-term damage that can be caused by flooding.
