Humidity plays a vital role in our everyday lives. Keeping indoor humidity levels under control is essential to maintain air quality and comfort. Humid air feels hotter, and high humidity levels can lead unwanted allergens—such as dust mites, mildew, and mold—to thrive, leading to a broad spectrum of health ailments.
High humidity in commercial spaces such as warehouses, offices, server rooms, and basements can cause stock damage in the short run and structural damage in the long run. Maintaining optimum humidity level and temperature is critical for the long-term storage of archives, artifacts, manuscripts, as excess moisture can cause irreversible damage.

Whether you live in a house, apartment, or work in an office or a factory, a dehumidifier ensures to keep your space’s humidity level free of excess moisture, making it comfortable and healthy. A commercial dehumidifier can help protect your machinery and merchandise from damage while maintaining a healthy work environment.
A commercial dehumidifier can remove deeply embedded moisture quickly and efficiently, speeding the drying process, and inhibit the growth of mold and preventing a musty smell. Most commercial and industrial units have wheels, providing easy mobility to areas requiring assistance. Commercial dehumidifiers generally use a desiccant or a compressed refrigerant system to remove air moisture and reduce humidity levels. These devices work by passing humid ambient air over a cold metal surface m leading the air’s moisture to condense on this cold surface. This collected moisture is drained into a reservoir or is piped to a suitable drain.
Commercial Dehumidifiers
Commercial dehumidifiers are reinforced with high-efficiency compressors and durable steel exteriors to endure the harshest conditions. These machines are designed for heavy duty uses and come with larger moisture removal capacities. Commercial dehumidifiers are often built using steel chassis or tough molded plastic casings, making them resistant to knocks and bumps suitable for long service life. Commercial dehumidifiers can efficiently operate in harsh weather conditions. They are equipped with powerful capacity fans, which pull a larger air volume, enabling higher moisture removal rates and a wider coverage area.
Commercial dehumidifiers have wide-ranging applications in factories, offices, building sites, storage facilities, and restoration. Commercial dehumidifiers are ideal for water damage restoration tasks, including excess water removal, high-speed drying, humidity maintenance, and protecting your business facility or restoring areas plagued by water and moisture damage. They are also used in production processes, dry materials storage, damp prevention in buildings, and drying out newly constructed masonry and plasterwork. Commercial dehumidifiers owned by construction companies or hired on rent come with portable wheels that ensure they can withstand being moved from site to site and withstanding damage.
Choosing a Commercial Dehumidifier:
Voltage: Generally, commercial dehumidifiers operate on a 230V supply, while there are some models available that can work as an 110v version or a duel voltage (both 230V and 110V) machine. If you use the dehumidifier for restoration tasks or on building sites, a dehumidifier with dual voltage is ideal.
Drainage: Most commercial dehumidifiers come with a dual drainage option; you can collect the water in the tank or add a hose to empty the water into drainage directly. Small tanks need emptying more frequently, and commercial dehumidifiers have an auto shut off when they are full. If you have a large space or dealing with high humidity levels, then it will be ineffective.
Condensate Pump: Unlike gravity drainage, pumps allow you to drain the condensed water at a distant location without physically raising the dehumidifier. When the container is full, it activates the pump and pushes water up and out of the unit. This water can be directed to a drain, out of a window, or any other location. Most pumps are capable of pushing water up to 15 to 17 feet vertically or horizontally.
Portability: Consider commercial dehumidifiers equipped with caster wheels, as they can be moved around easily. Some models are also equipped with handles that help in improved portability.
Advanced Air Filtration: Advanced air filters can capture fine particles and debris and protect sensitive compressors from damage.
Humidistat: A humidistat automatically maintains humidity at the pre-set level, ensuring that you can use the machine to run continuously without being present on the job site.
Hot gas defrost: The condensation fins can over time get frosted up, restricting airflow through the unit and limiting its efficiency. Commercial dehumidifiers are equipped with a Hot Gas Bypass System, enabling them to continue operating in lower temperatures. Such a feature is handy when a dehumidifier is used in spaces with lower temperatures, like warehouses.

Furthermore, they are also valuable for water damage restoration duties and high-speed drying.
Are Commercial dehumidifiers heavy?
Commercial dehumidifiers’ weight can range from 50 lbs. to as much as 353 lbs. The all-steel construction of most of these dehumidifiers lends itself to their heavy-duty, durable nature and their increased weight. But generally, these dehumidifiers are put in place and not moved unless used by a commercial restoration company.
Can I leave an industrial dehumidifier on all night?
If required, you can leave the commercial dehumidifier for 24 hours. However, be aware that the machine will always generate noise while operating. You can consider running the industrial dehumidifier from early morning until late evening and then turning the machine off.
How much water will a commercial or industrial dehumidifier remove?
The water removal rate denotes the number of pints per 24 hours a dehumidifier can remove. Commercial and industrial units can remove up to 160 pints, while most residential dehumidifiers are limited up to 70 pints.
How loud are Commercial dehumidifiers?
Commercial-grade dehumidifiers are louder than single-room dehumidifiers. Luckily, they’re typically in basements, crawl spaces, and industrial settings where noise isn’t a primary concern. Nevertheless, you can check the decibel rating provided by the manufacturer and select the machine accordingly if you are concerned with high noise.
How well do commercial dehumidifiers work?
Commercial dehumidifiers are powerful and can effectively remove 150 to 250 pints of moisture per day.
Why Do Commercial Dehumidifiers need a Defrost System?
Ice can build up on the evaporator coils of a refrigeration dehumidifier under some humidity and temperature conditions; it can hinder air circulation and eventually create a block covering the coils and prevents the machine from running optimally and end up causing damage to the unit. In addition, the accumulated ice can distort or deform mechanical elements in severe cases, thereby permanently damaging the machine. Therefore, high-quality dehumidifiers usually come with a defrost system. This system will turn the device off and enable the ice-covered evaporator coils to defrost. The unit will automatically restart as soon as the coils have been defrosted.
