Important Aspects to Consider a Commercial/Industrial Dehumidifier

If you are going to buy dehumidifiers for commercial space for the first time, it is necessary to know what you need. Not all industrial dehumidifiers will cater to your individual needs. Here’s a brief overview of the critically important aspect to consider when buying industrial dehumidifiers.

Coverage Area:

Whether you want a dehumidifier for a large garage, basement, or warehouse, the coverage area should be your first consideration. Do check the place a commercial dehumidifier will cover before purchasing. Some models offer up to 10000 cubic-feet coverage and some even higher. Buy a unit that can handle the commercial space you want to dehumidify.

Built-In Pump:

Commercial and industrial dehumidifiers must come with a built-in pump to ensure maximum convenience. It will expel the accumulated water automatically through a hose. So, you won’t have to manually drain the water tank when it’s full.

Noise Level:

An industrial dehumidifier can get annoying rather quickly. Noisy units can cause extreme disturbance during your all-important business meetings. Therefore, always check a unit’s noise level. We recommend that you get a model with 50 DB or lower noise level.


Portability is a bonus as you can keep moving the unit to different areas. Choose a model with wheels and handles to place them wherever you want.

Auto Shutoff/Restart:

Auto Shutoff/Restart feature is a blessing if your office is in an area where power failures are more frequent. Such a unit will automatically restart when power resumes and shutoff when water tank is full.

Built-In Humidistat:

It will provide temperature readings and humidity-related information in real-time.

Low-Temperature Operation:

If you want a dehumidifier for warehouses, basement, or garages, buy a unit that can operate in low temperatures. Choose a model that works equally effectively in winters as in summers.
