Cons
• No humidistat
• Higher cost

How Does a Dehumidifier Work?

Before you choose a dehumidifier, it’s important to at least have some idea how it works. This way you’ll also know when it’s not functioning properly. The basic purpose of any dehumidifier is to reduce humidity levels by removing excess moisture from the air. The two main types of wall-mounted dehumidifiers — refrigerant and desiccant — are classified by the moisture removal method they utilize.

Refrigerant

The most common type of dehumidifier is called the refrigerant or compressor. It works similarly to an air conditioner as it uses a compressor to pump the refrigerant to and from the condenser and evaporator coils to facilitate moisture removal.

(Video) Best Crawl Space Dehumidifier of 2022 | The 5 Best Dehumidifiers Review

A fan draws warm, moist air into the dehumidifier and passes it over the cooling coils. As the temperature decreases, the air loses its ability to hold water vapor. Moisture condenses and drips down into a reservoir or flows out through a drain hose. A heavy-duty ceiling-mounted dehumidifier usually includes some kind of drain trap at the bottom to prevent leaks or even a built-in condensate pump to automatically drain the collected water. Once moisture is removed, the dryer air is reheated before it is released into the room.

Top 7 Best Ceiling-Mounted Dehumidifiers - 2022 (8)

Because of the condensation process, a refrigerant dehumidifier generally performs best in warm and humid climates. Most residential units can only operate in temperatures as low as 41°F, while the efficiency starts to decrease as the air gets cooler. Additionally, condensate may start freezing inside the machine when temperatures drop. To avoid this, this type of dehumidifier features an auto-defrost function which stops dehumidification periodically to melt the ice that has built up on the coils. Some commercial refrigerant dehumidifiers use advanced technologies to allow operation in lower temperatures with less downtime, saving more energy.

Desiccant

The other main type of dehumidifier uses some kind of desiccant that extracts moisture from the air until it is fully saturated. The most noticeable difference from the more common refrigerant dehumidifier is that a desiccant unit is lighter and quieter since it does not use a compressor. All it really needs is the desiccant chemical itself, which determines the dehumidifier’s capacity, area of coverage, and renewability.

Commercial desiccant dehumidifiers prominently feature a rotating wheel filled with hygroscopic silica gel. To operate, they usually work with two separate air streams, the process air and reactivation air. The humid air is pulled into the dehumidifier by a fan and passes through the process zone of the desiccant wheel. The moisture from the air transfers to the surface of the desiccant, resulting in dryer air that is released back into the room.

A heater warms the second air stream, which may come directly from the room or from a portion of the already dehumidified air. The reactivation air passes through the remaining part of the desiccant wheel in the opposite direction of the process air. The moisture now transfers from the desiccant to the air, thus reactivating the desiccant so it can extract moisture again. This warm and moist reactivation air is then vented outside. The wheel rotates continuously and the cycle repeats.

A desiccant dehumidifier is ideal in cold and dry conditions that need strict humidity control. Because desiccant dehumidifiers don’t work by cooling down the air, they can continue to operate in lower temperatures. Compared to refrigerant dehumidifiers, there is almost no risk of frost since there is no condensate formed at any point and the heater constantly warms the inside. Buildings and construction materials that are hard to dry often need a professional desiccant dehumidifier.

Factors to Consider Before Buying a Dehumidifier

Ceiling-mounted dehumidifiers offer high-capacity performance in a tough and durable construction and you want to make sure you are getting the most out of your investment. To do this, consider the following features before you make a purchase.

Top 7 Best Ceiling-Mounted Dehumidifiers - 2022 (10)

Dehumidifier Capacity

Perhaps the most important specification for any dehumidifier is the total amount of moisture it can remove per day. For commercial dehumidifiers, we measure this in two ways.

The AHAM capacity is the measured under the conditions of 80°F and 60% RH, the average type of environment as recommended by the Association of Home Appliance Manufacturers. This should be closer to the performance of the dehumidifier in actual use. On the other hand, the maximum capacity is the largest amount that the unit can collect per day at saturation (90°F and 90% RH). For desiccant models, the capacity is not measured the same way since they do not produce condensate.

The size of the dehumidifier you need mainly depends on the size and condition of the space you need to dehumidify. To help determine which capacity is best for you, measure the dimensions of your space and the humidity level. A larger space and higher moisture content both require a more powerful dehumidifier. However, this doesn’t mean that the highest capacity is always the best.

Coverage Area

As mentioned, you need a dehumidifier that can handle as much space as you have. You can expect a dehumidifier to accomplish its task more quickly in a smaller area than a larger one with similar humidity levels. While a higher capacity usually covers a larger space, it can vary per brand and model. Dehumidifier manufacturers should indicate this for each model.

Another specification to note is the airflow, in cubic feet per minute (CFM). This is the volume of air that the dehumidifier can process per minute. The airflow rate does not necessarily relate to the coverage area and capacity, but it’s important to note when using dehumidifiers for deep drying.

Drainage

Most commercial dehumidifiers, especially when mounted on a wall or ceiling, have options for continuous drainage. Simply attach the drain hose (which may be included with the unit) onto the outlet port typically on the side or at the back of the unit. If the dehumidifier is mounted on the ceiling, place a tray beneath the outlet and make sure the hose is directed down towards the drain to prevent water leakage.

(Video) Top 10 Best Commercial Dehumidifiers in 2022 Reviews

Some heavy-duty dehumidifiers may also come with a built-in condensate pump for automatic draining in any direction even vertically up to a certain height. This is particularly useful for large spaces without a floor drain available. If you’ve already found a dehumidifier you like but it doesn’t have a pump built-in, you may opt for a separate external unit.

Meanwhile, desiccant dehumidifiers do not need drainage since they don’t produce any condensate.

Low-Temperature Operation

Most dehumidifiers work best in warm and humid climates. If you get extremely cold winters, then you need a dehumidifier that can operate even when temperatures drop to 41°F or below. Commercial dehumidifiers are typically built to handle harsher conditions than residential dehumidifiers. They are equipped with advanced defrosting systems to automatically melt frost and protect the internal components. However, compressor dehumidifiers are still limited by the operating temperature range. On the other hand, desiccant units are particularly efficient in low temperatures down to -4°F. You can find many benefits of this feature in commercial or industrial applications.

Humidistat

A built-in humidistat monitors and automatically adjusts the humidity in the area. You can set your target humidity level and the unit will shut off once this is reached, thus reducing your energy consumption. When the dehumidifier senses humidity above your setting, it will start operating again. Most wall- and ceiling-mounted dehumidifiers work with a remote digital humidistat for more convenient operation.

Build Quality

Industrial dehumidifiers are mostly built with steel or heavy-duty plastic to make them more durable and resistant to harsh environments. The metal or rotomolded casing gives them a rugged structure ideal for a variety of commercial applications. The unit’s construction also protects the internal components from harmful elements and chemicals in job sites. Lastly, take note of the product’s warranty policy. A longer warranty period typically means the manufacturer has confidence in the quality and durability of its product.

Uses for a Ceiling-Mounted Dehumidifier

Top 7 Best Ceiling-Mounted Dehumidifiers - 2022 (11)

Ceiling-mounted dehumidifiers are often used in large commercial areas where floor space is extremely valuable. Although most are used in commercial spaces, they can be beneficial for a variety of purposes in both residential and industrial applications.

While the typical portable dehumidifier is smaller, it needs a lot of open space on each side to promote airflow. Ceiling-mounted dehumidifiers give you more flexibility in installation. If you have limited space in your house for multiple portable units, you can use a high-capacity dehumidifier, hang it from your basement ceiling or between floor joists in the crawl space, and then connect it to your air ducts to cover the whole house. It can also be a perfect solution to high humidity if you have limited space in a damp basement, laundry room, or indoor pool.

Considering the costs of purchasing, installing, and operating them, ceiling-mounted dehumidifiers are more commonly used in commercial spaces. Merchandise or any goods for sale or storage can be damaged when exposed to excess moisture. High humidity may also cause electrical equipment to overheat and malfunction. A commercial-grade ceiling-mounted or wall dehumidifier is an ideal solution to humidity control in spaces for storage or transport of goods and equipment.

Additionally, indoor facilities such as pools, spas, and greenhouses where water is always present, require high-capacity dehumidifiers to keep humidity down to comfortable levels. Excess moisture combined with other chemicals in the air can be dangerous to people’s health and damaging to furniture and structure.

Lastly, services involving food preparation, cooking, and cleaning may cause high moisture levels. It’s critical to meet requirements for temperature and humidity levels in these industries.

Proper Usage, Maintenance of Ceiling-Mounted Dehumidifiers

Ceiling-mounted dehumidifiers offer greater flexibility in installation. You can place it in many different areas in a residential or commercial property. Just like any other dehumidifier, they must be operated in an enclosed space to work effectively. It’s best to keep doors and windows closed as more outside air enters the job will be harder for the dehumidifier.

When using the dehumidifier, find the right humidity setting for its purpose. Most dehumidifiers feature a built-in humidistat to adjust the room humidity to your set humidity level. The ideal indoor humidity range is from 35% to 55% RH. Depending on the ambient temperature and application, you may need to select a different setting. In any case, keep your dehumidifier operating only when it’s absolutely necessary.

Dehumidifiers usually require little to no maintenance, but it’s still imperative to perform routine cleaning to take extra care of your unit. When installing your dehumidifier on the ceiling, make sure that it can still be accessed for maintenance and cleaning every few weeks. Consult your manual for specific instructions on installation, usage, and maintenance.

Frequent cleaning helps maintain proper functioning and prolong the life of your dehumidifier. The unit collects not only moisture but also dust, dirt, and all kinds of impurities in the air. When it builds up inside the unit, it can contaminate the air your dehumidifier releases into the room. Clan the unit’s exterior as soon as you notice dust or grime. Wipe it with a damp cloth and vacuum the inside to remove any remaining debris. Wash or replace the filters as needed.

Lastly, take note of the unit’s operating temperature range. Most dehumidifiers work best at temperatures 56°F and above unless it’s specifically designed for colder conditions. If you operate in colder environments, the condensate may freeze on the coils and damage the machine permanently. If you really need to operate in lower temperatures, a desiccant dehumidifier is designed specifically for this purpose.
