Commercial Dehumidifier Buying Guide
After reviewing the best options available for commercial dehumidifiers, let’s take a look at some factors that determine what sort of commercial dehumidifier you would need.
Humidity Levels
The humidity levels of your region will govern your choice of a dehumidifier. Not all humid areas have the same moisture levels. Some are more humid than others.
Areas with very high humidity would need a higher pint per day (PPD) capacity than areas with lower humidity levels. Assess the moisture level in your region and then make the right purchase.
Installation Area
Users install a dehumidifier in all sorts of places. Be it garages, warehouses, or basements, a dehumidifier is usable anywhere.
However, if you plan to buy a dehumidifier for basement or crawl spaces, make sure it is compact and low in height. Open spaces can house bulky and tall dehumidifiers.
Drainage Outlet
When figuring out the installation place for the dehumidifier, you must also consider the drainage options.
Condensate water formed after the removal of moisture from the air needs discharging. A hose is connected to the dehumidifier that carries the water from the appliance and passes through a window or a hole in the wall. The water is then let out the other end.
Make sure that you have a window or some arrangement for the hose to discharge the drainage water.
What are Commercial Dehumidifiers, and How do they Work?
A commercial dehumidifier is a high-grade dehumidifier built to tackle large spaces and excessive moisture. These appliances are designed to perform continuously and remove moisture from large spaces such as warehouses, storage areas, shops, and offices.
These appliances use a hydrophilic material, such as silica gel, to attract water droplets suspended in the air. A fan pulls in moist air, which then passes through a rotating wheel lined with silica gel. The silica gel removes water from the air, and the air is let out of the dehumidifier.
This way, a dehumidifier effectively reduces humidity levels indoors.
Why Buy a Commercial Dehumidifier Over a Consumer-Grade Unit?
While consumer-grade units are ideal for homes and small spaces, they won’t suffice in a commercial setting. Commercial settings include large open spaces characterized by high moisture levels. Therefore, a small unit would not effectively reduce humidity inside.
A commercial dehumidifier is built to tackle such circumstances and can efficiently remove water from highly humid air.
Moreover, a consumer-grade dehumidifier would have to work harder and consume more energy for the purpose.
However, a commercial-grade humidifier is built on energy-efficient designs and consumes less energy, lowering power bills.
What to Look for in a Commercial Dehumidifier
Below are the basic features you should consider when buying a commercial dehumidifier so that your money doesn’t go to waste:
Coverage Area
Coverage area is measured in square feet and determines how big a floor plan the dehumidifier can work in. Dehumidifiers have capacities best suited to certain room sizes.
Commercial dehumidifiers have a coverage area between 1000 and 7000 square feet. Smaller spaces like offices, shops, or parlors will make good use of commercial dehumidifiers with a coverage area of 1000-1200 square feet.
However, large warehouses and storage areas or showrooms would need dehumidifiers made to tackle bigger spaces. In such circumstances, make sure to invest in a dehumidifier with a coverage area of 4500-6000 square feet.
For the best results, measure the floor area of your space and then tally it with the coverage range of the dehumidifier.
Air Flow
The airflow determines the amount of air processed by the dehumidifier to remove moisture. As a general rule, the higher the airflow, the better. Airflow is measured in cubic feet per meter (CFM), and ideally, anything above 250 CFM is good.
Tank Capacity
The condensate formed after removing moisture from the air is collected in the appliance tank as drainage water.
Usually, the tank capacity is smaller than the dehumidifying capacity of the appliance. The latter determines how many pints of water are removed in a day. Typically, this capacity varies from 50 to up to 200 pints a day.
Make sure that both these capacities are sufficient enough to cater to the humidity levels in your area. Otherwise, the appliance won’t make a difference, or the tank would overflow if the model does not support automatic drainage.
Noise Levels
Noise levels are related to airflow. The higher the airflow, the higher the noise. Because these are commercial-grade models, they are bulky and process large amounts of air. Understandably, they do have some operational noise.
A good balance between the airflow and noise level is 250 CFM and noise level below 55dB. When deciding on a dehumidifier, do take into account its noise level. The noise level can also be managed by placing the appliance in the basement or in a farther corner to prevent disturbance.
Drainage
As discussed earlier, dehumidifiers produce drainage. Most modern models have automatic drainage where users have to attach the hose to the appliance and let the other end of the hose out of a window or a door. The water is then drained through this hose outside.
Some appliances work on gravity drainage and use no specialized machinery to force the water out. Others use pump drainage that uses a water pump to force the water from the appliance through the hose and out of the room.
Assess your needs and see if you would need a pump drainage system or if gravity drainage suffices. We advise not to go for manual drainage because you will have to repeatedly empty the water reservoir yourself with those models.
Energy Efficiency
Because commercial-grade dehumidifiers are large appliances that process volumes of air, they consume a significant amount of energy. Therefore, we advise you to always look for certified energy-efficiency models that run on low power and do not add to the electric bill.
Maintenance Costs
Another factor that would determine the operational cost is the maintenance of the dehumidifier. We advise you to invest in models that come with removable and washable filters.
Otherwise, filters that prevent dust and debris from entering the dehumidifier would need replacing every time. This would increase running costs.
Other than that, look for models that come with a good-quality hose that does not break easily.
Pros and Cons
Like all things, there are several pros of using commercial dehumidifiers. Accompanying them are some cons as well. Let’s take a look at both.
Pros
Tackles Large Spaces
Commercial humidifiers can remove damaging moisture from large spaces. They minimize the chances of mold and mildew growth and keep the environment fresh and breathable.
Protects Wood and Stored Items
These appliances are widely used in commercial setups, including warehouses and showrooms. Many warehouses store food items that might go bad if moisture persists.
In such areas, a commercial dehumidifier plays a key role in preventing food spoilage.
Moreover, wood furniture is prone to damage in the presence of moisture. A dehumidifier protects the wood in homes and furniture showrooms.
Reduces Stuffiness
You spend a good part of your day in your workplace. Commercial settings employ many people, and therefore in humid areas, they become quite stuffy. The unpleasant environment not only makes it difficult to breathe but also makes the area hot.
A commercial dehumidifier lowers moisture levels in these large and busy spaces, making them much more livable.
Cons
Noise
Commercial dehumidifiers are large appliances processing lots of air at a time. Therefore, they produce noise. While some models may produce lesser noise, the noise is rarely entirely absent.
Cleaning and Maintenance
With proper cleaning and maintenance, commercial dehumidifiers will definitely last longer than expected. Here are a few tips on how to properly clean and maintain commercial dehumidifiers.
- Unplug the dehumidifier and move it away from the power outlet.
- Drain the collected water via the hose.
- Next, take a damp cloth and wipe it down on all sides. Make sure to rub off any dirt marks.
- Reach and take out the filter.
- Wash the filter gently with cold water and rub it gently to remove all the stuck dirt and debris.
- Let the filter dry completely.
- Check the coils of your dehumidifier. Make sure that they are not dirty; otherwise, they can cause overheating. Vacuum the coils to clean them.
- Detach the drainage hole and inspect it for blockage. Remove any dirt balls or other blocking objects.
- Make sure that the hose is not ruptured from any part.
