The Dangers of Excess Humidity

Humidity refers to the amount of water vapor in the atmosphere. Humid air feels wet, thick and heavy, and may also have a musty or unpleasant odor. Indoor humidity can represent a threat to both health and property — and that means it can hurt your business. It can be caused by climate or other factors. Mold, condensation, water damage or other signs of excess moisture can indicate a humidity problem.

Fortunately, there’s an easy solution to controlling humidity indoors. A commercial dehumidifier can regulate the moisture in the air of any interior space — from a warehouse to an office to a crawl space — to give you peace of mind. Whether you are a facilities manager, maintenance manager or HVAC contractor who works in the field of hospitality, higher education, storage, manufacturing or production of perishable goods, you want to keep costs down and protect your goods, property or products. Proper humidity control also helps create a pleasant, healthy environment for workers, clients or customers, and other visitors to your commercial space.

With nearly three decades of experience in the industry, we can help navigate the features of different models of commercial dehumidifiers to compare before you buy — and help you stick to your budget. Our commercial dehumidifier sizing form and this guide offer helpful tools to help you narrow down the options for your business.


Businesses that Need Dehumidifiers

Almost any commercial enterprise can benefit from a dehumidifier, but some specific types of businesses and industries especially need indoor humidity control.  These include:

  • Cleaning and restoration services
  • Laboratories
  • Office buildings
  • Warehouses or other storage facilities
  • Retail stores
  • Pools, spas, hot tubs and other moisture-generating environments
  • Food or perishable goods production or storage facilities
  • Marijuana or other plant growing facilities
  • School or health club gyms or locker rooms
  • Factories
  • Businesses with basements or crawl spaces
  • Any commercial space with moisture issues or moisture-sensitive items


Those businesses that involve flood remediation and restoration can also often benefit from high quality commercial grade dehumidifiers that are portable. Hotels, schools, gyms and other facilities with pools or hot tubs need dehumidifiers designed for those high-moisture environments. Companies with perishable items — such as food — may need units specifically manufactured to work in low temperature environments.

Even if your business does not involve perishable or moisture-sensitive goods, signs of excess moisture and humidity may indicate the need for a commercial dehumidifier. Those can include:

  • Collected water inside the space
  • Pooling water outside the space
  • Condensation
  • Wood rot
  • Mold or mildew
  • Musty smells
  • Thick or wet-feeling air
  • Pests or signs of pests
  • Sagging areas of the floor above

An indoor environmental systems expert can help you evaluate whether your business needs ongoing humidity control.

Why to Buy Ebac

When shopping for a commercial dehumidifier, you may wonder what brands stand out among the rest. Ebac is one such brand.

Headquartered in the United Kingdom, Ebac is an industrial manufacturing company that specializes in commercial dehumidifiers. It is a private, family-owned business with an excellent track record and customer service. The North American division of the company is based in Newport News, Virginia. In North America, Ebac offers products that cater to companies needing cleaning and restoration and HVAC humidity solutions for residential, municipal and commercial settings. All units are manufactured in the UK.


Ebac makes a range of rugged, industrial-quality dehumidifiers. They also offer replacement parts. Do you need a commercial dehumidifier with a pump? Or perhaps a model that is designed for a specific purpose, such as repairing water damage or maintaining a climate in an indoor area with a pool or spa. Ebac manufactures dehumidifiers that are:

  • Portable
  • Wall-mountable
  • Desiccant, or use a special air drying process
  • Designed specifically for restoration
  • Designed specifically for swimming pool and hot tub areas

An Ebac commercial dehumidifier can remove as much as 560 pints per day or more, depending on the model. They can also work in as low as -4 degrees Fahrenheit, if your business has temperature control needs. Prices range from about $700 to $3,500.

Specifications to Compare

Before you start shopping, it helps to gather some information about your business. The factors that will determine which model of commercial dehumidifier makes sense for your business include:

  • Location
  • Dimensions of space 
  • Materials that make up the space (Length, Width, Ceiling Height)
  • Degree of insulation
  • Humidity level
  • Desired humidity level
  • Average air temperature

If you talk to an indoor environmental specialist, they will also want to know whether the space contains a pool, hot tub or spa. The amount of moisture a commercial grade dehumidifier can remove from the indoor air can range a great deal. You can find units that remove any amount from about 15 pints per day — or PPD — to nearly 575 PPD. Airflow ranges from about 170 to 1759.

A pro will also want to know your electrical requirements and what kind of voltage and current your electrical system can handle. Electrical specs for a commercial dehumidifier range from about 115 volts to 460 volts.

Once you have the information you need to start shopping, refer to our comparison chart to narrow down your choices of Ebac models based on size, electrical specs and more.

Note that Ebac’s smallest models  — including the CD30, CD35, RM40 — use the refrigerant R134a.  All other refrigerant style models contain R407c, which is the direct replacement to R22. As of January 1, 2010, per EPA regulations, no new manufactured product can contain R22, which causes ozone layer depletion.

Features to Consider

In addition to the sizing and electrical specs, your business may require additional features. Does the unit you purchase need to be ducted? Some units allow for ducting to or from another room or area.


Do you need a wall mounted unit, or a stand alone unit? Some of the stand-alone units can be wall mounted with an optional wall bracket. You may, on the other hand, require a portable model. Some units have carrying handles as well as castors for easy maneuverability, which may be ideal for cleaning, restoration and even pest control companies.

Some features to note: Hot gas defrost and reverse cycle defrost both automatically melt away frost buildup providing effective operation at low ambient temperatures. Reverse cycle defrost allows the unit to function smoothly in temperatures down to 33 degrees Farenheit without frost build-up.

Humidistats can also be important features to some businesses. An internal electronic humidistat automatically switches on and off to save energy — and money — by maintaining the desired level of humidity with intermittent operation. An adjustable humidistat allows you to set your desired level of humidity control. A humidistat that can be controlled on the unit or remotely works well for businesses requiring a certain RH — or relative humidity — number.

An integral high capacity condensate pump allows the unit to pump out the collected water, as opposed to having a gravity tube that leads to a drain. This is a good feature for commercial dehumidifiers that need to be installed in basement areas because the water is able to pump out to ground level. If a floor drain is not available for any application, a condensate pump is recommended.

Companies that do cleaning and restoration sometimes need to keep track of the hours a unit runs on a jobsite so they can bill it properly, which makes an hours run meter feature handy.

Talk to an indoor environmental solutions specialist about any specific needs or constraints you may have, and to make sure that any model you are considering has the features you need.
