The Buying Guide

What is it actually?

If you spend much time researching dehumidifiers, you’ll come across three general categories: residential, commercial, and industrial. As you might expect, residential units don’t need to have the processing power that industrial commercial units do, so they’re usually smaller, quieter, and cheaper. They often have a sleek design, so they don’t look completely out of place in a home’s décor.

When it comes to dehumidifiers, the words “commercial” and “industrial” are often used interchangeably because these models overlap in terms of features, design, and power. Unlike their residential counterparts that consist of lightweight plastic, commercial dehumidifiers are made of steel or heavy-duty plastic. They are therefore more durable, larger, and more expensive compared to residential machines.

Does this mean you can’t use an industrial commercial at home? Not necessarily, although some may consider purchasing a commercial machine for a single home a bit of overkill. However, if you have a large enough house constantly exposed to high humidity levels and extreme temperatures, it might be worth get a house dehumidifier. If you can afford it and can take the noise, the industrial commercial would be the best choice. Do note that commercial dehumidifiers will also be the better option in cases where your home has an indoor pool or very damp crawl space or basement.

Factors to Consider

When searching for the perfect commercial dehumidifier for your needs, there are some features that you should look for in your machine.

Capacity

Capacity is the amount of moisture a dehumidifier can extract from the air in a day, and it is normally measured in pints. If you have a large commercial space, you should look for at least a 50 to 70 pint dehumidifier capacity. Anything less might not be sufficient for your needs, and you will end up having to buy multiple units or move the unit around all the time to keep the humidity level satisfactory.

Built-in Humidistat

Knowing the exact humidity levels in your establishment is important as it will tell you whether the dehumidifier is working or not. Thus, one of the most important features of the best commercial dehumidifier is a built-in humidistat.

Operates in Low Temperature

Large, empty spaces like warehouses usually aren’t heated in the colder months. Unfortunately, some of the best dehumidifiers stop working at certain temperatures, so make sure you look for energy star models that can work even when temperatures fall to 32 degrees Fahrenheit.

Automatic Drainage

We all live busy lives, so having to check whether a water tank is full every so often just doesn’t fit into our list of priorities. Make sure you look for units that have a drain outlet that will allow the dehumidifier to operate continuously without too much attention.

Material Quality

As mentioned before, an industrial commercial dehumidifier consists of either steel or heavy-duty plastic. However, some manufacturers cut corners by making the dehumidifiers from low-quality, lightweight plastic. Don’t mind the increased cost of a quality build— it will pay off in the long run.

Noise Level

The noise from an industrial commercial dehumidifier can get loud to the point of being annoying, so make sure to look for a unit that operates quietly if that is a concern.

What are the dehumidifier types? (Automation, Energy Efficiency, Pints, Portable)

As you already know, dehumidifiers remove excess moisture from the air and help to control the level of humidity in a given space. However, what you might not know yet is that they can differ in how they accomplish this. There are two main categories of commercial dehumidifiers, and you can differentiate them according to the technology that they use: desiccant or refrigerator coil.

Desiccant

Desiccant dehumidifiers reduce moisture in the air by moving air through a rotor that contains a water-trapping material known as a desiccant. The most common desiccant material used in dehumidifiers is silica gel, which is technically not a gel but a porous and granular configuration of silica. The unique structure of the silica gel allows it to absorb moisture.

The desiccants absorb the water from the air passing through the rotor, and the dried air is blown back out to the building. Water collected by the dehumidifier in its desiccant wheel is removed by vaporizing the water out of the silica and then moving it through ducts and out of the building.

Refrigerant

Refrigerant dehumidifiers are the most common type of commercial dehumidifiers, and they work by condensing moisture in the air. Humid air is drawn from the surroundings and brought into the dehumidifier, and then passes over evaporator coils that cool the air, causing water vapor to condense. The condensation from the cold coils drops down into a collection tank or through a drain hose which automatically drains the water from the dehumidifier.

Once the dehumidifier removes the moisture from the air, the dry air then passes through warm condensing coils, heating it before it exits the machine. Most dehumidifiers remove the dry air with increased pressure, directing it at specific areas to further increase dehumidification.

Crawl Space vs. Commercial Dehumidifiers Models

Crawl spaces may get wet due to cracks in the building’s foundation or walls, burst pipes, recent flooding, or a lack of general maintenance. Mold, mildew, and other parasites love living in crawl spaces because they provide shelter and the damp air and darkness facilitate their growth.

The problem with crawl spaces is that it is easy to forget about them until you have an infestation in your hands, which is why it is important to purchase a dehumidifier to ensure moisture removal in the area and prevent such problems. If you have a very damp crawl space, you might be on the fence about whether to purchase a crawl space dehumidifier or an industrial commercial dehumidifier. The answer to this problem is relative—it depends on the size of the space and how severe the humidity and air quality can get.

While commercial dehumidifiers can remove more excess moisture than your standard crawl space dehumidifiers, you have to consider whether there’s space or even the need for it. After all, there’s a reason the industry calls them “crawl space dehumidifiers.” They’re manufactured specifically for crawl spaces. An industrial commercial dehumidifier is best for other areas of the home or building, such as indoor pools and basements.
