Commercial Dehumidifiers

Commercial dehumidifiers are essential pieces of equipment for damage restoration professionals and the operation of many other industrial businesses.

Removing moisture from the air prevents mold from forming, salvages building materials and protects expensive equipment from moisture damage.

It also helps improve indoor air quality and habitability by removing uncomfortable levels of indoor humidity and condensation.

Types of Commercial Dehumidifiers: LGR vs Conventional Models

Conventional Dehumidifiers Usage Areas

You will find two main types of commercial dehumidifiers for sale. Which type is right for you will depend on the level of moisture that you need removed and any size limitations.

When you buy commercial dehumidifiers, your two primary options include conventional or low-grain refrigerant (LGR) dehumidifiers. Here is how the two compare:

Conventional Dehumidifiers

Conventional dehumidifiers can be used in most water damage remediation or indoor climate control situations.

A conventional dehumidifier sucks in surrounding air and passes it through a series of cooling coils.

By cooling down the air, the unit can remove moisture as it condenses. The unit also contains a heat pipe that prevents frost from forming.

Conventional dehumidifiers are less efficient than LGR dehumidifiers at removing high volumes of moisture.

This makes conventional dehumidifiers suitable for moderate water damage situations or ongoing humidity control.

The conventional types are typically more portable commercial dehumidifiers, which makes them easy to transport to and from different job sites. They are also usually less expensive than industrial LGR dehumidifiers are.

LGR Dehumidifiers

Low grain refrigerant dehumidifiers (LGR) have the greatest moisture removal capacity when it comes to quickly removing water from the surrounding environment.

When emergencies such as a burst pipe or massive flooding cause more sever water damage with higher levels of saturation, you are morel likely to want an LGR model.

LGR dehumidifiers use a double-cooling system that lowers the temperature of the air that enters the machine. This causes more condensation to form on the coils, and more moisture can then be removed. Because an

LGR dehumidifier pre-cools air through a heat exchange, it can remove more water per kilowatt of energy compared to conventional units.

Grain is a term used to describe the weight of water per pound of dry air. LGR dehumidifiers can remove water to below 55 or even 40 grains per pound.

An LGR dehumidifier’s capacity is also measured based on how much water it can remove given a certain relative humidity and room temperature.

You may see that the capacity of an LGR dehumidifier can vary between removing 75 to 99 pints per day (PPD) because it depends on the humidity levels and temperature of the environment.

These dehumidifiers are an important piece of water damage restoration equipment that can effectively remove moisture from carpets, walls, wood and other saturated building structure materials.

This makes them ideally suited for extreme water damage and flood cleanup after a natural disaster, burst pipe or other event.

AHAM and Saturation Measurements for Commercial Dehumidifiers

There are two different metrics used to measure a commercial dehumidifier’s performance, AHAM and Saturation.

Both of these describe conditions at which maximum water removal capabilities are measured. It is important ot understand these standards of measurement so that you can select the right dehumidifier for your needs based on moisture removal capabilities.


AHAM conditions are the conditions recommended by the Association of Home Appliance Manufacturers based on average levels of humidity and average temperatures.

AHAM measurement are taken at 60 percent humidity and 80 degrees Fahrenheit. Measurements taken in these conditions are intended to give you an idea of how a dehumidifier will perform in a typical environment.


A saturation rating is taken at 90 percent humidity and 90 degrees Fahrenheit, which represents much more extreme conditions.

This is to give you an idea of a commercial dehumidifiers maximum water removal capabilities, even though environments like this are not likely to be encountered often in the field.

You should expect moisture removal capabilities to be closer to AHAM ratings in most situations. In environments with higher levels of moisture you may exceed the AHAM rating, getting closer to saturation measurements.

Keep in mind these performance metrics in mind when determining the industrial dehumidifier that best fits your needs.

How to Choose the Right Industrial Dehumidifier

When choosing the right commercial dehumidifier for your needs you will want to consider size and portability, water removal requirements, and the types of environments that you will be using the dehumidifier in.

When choosing the right industrial dehumidifier for your needs you will want to consider size and portability, water removal requirements, and the types of environments that you will be using the commercial dehumidifier in.

You should consider:

  • Size and Portability: The size and portability is an important consideration, and will depend on the available space in your truck or van that you use for transporting equipment and the man power that you have available to move equipment in and out of job sites.
  • Water Removal Capabilities: Different commercial dehumidifiers have different water removal ratings. You want to make sure that the restoration dehumidifier you buy is powerful enough to do what you need, but there’s no need to spend the extra money on a dehumidifier that can remove more water from the air than needed. Use our guide to understanding AHAM and saturation ratings to help you understand what each model is capable of.
  • Types of Environments: The porosity of a material will affect its ability to hold water and how much water it can hold. The types of materials you want the dehumidifier to help you dry may affect the type of commercial dehumidifier best suited for your work. For example, concrete surfaces will be more easily dried than carpet or drywall.

Industries Served

Commercial Dehumidifiers serve an important purpose and are used by many professionals in a variety of industries, including:

  • Water damage restoration
  • Fire damage restoration
  • Greenhouse climate control
  • Mold remediation and prevention
  • Indoor climate control in buildings

Industrial Dehumidifiers are effective both for prevention of problems that can be caused by moisture, such as rust in equipment, and remediation of water damage after a flood, fire, or other event

Water damage restoration and mold remediation professionals rely on dehumidifiers in order to successfully remediate property damage.

Restoration Dehumidifiers may also be used on an ongoing basis inside schools, shopping centers, processing plants or other structures that may have high levels of humidity.

Building owners and operators work hard to ensure their buildings and facilities are as clean as possible. Part of this is ensuring there is no condensation that can threaten a building’s cleanliness, air quality, or cause mold or bacteria to grow.

Commercial Dehumidifiers for Water Damage Restoration and Disaster Cleanup

When water damage affects a building, it’s critical to use thorough restoration tactics to get the damage, water saturation and humidity levels under control before the situation gets worse.

Using a commercial dehumidifier manages moisture in emergency situations, and it’s important for the following reasons:

  • Protecting building structure from damage
  • Preventing metal components from corroding
  • Preserving decor elements like furnishings and window treatments
  • Eliminating the potential for mold to grow and spread
  • Controlling and reducing water retention in building surfaces
  • Reducing condensation and drying affected materials

Using heavy-duty commercial dehumidifiers is the best option when water damage threatens a building’s integrity. High-capacity dehumidifiers can help salvage building materials and prevent further damage.

Overall, industrial-strength dehumidifiers — especially commercial LGR dehumidifiers — are the most efficient way to remove moisture and reduce humidity levels quickly in a damaged building.

How to Use a Commercial Dehumidifier: Best Practices for Restoration

How you use a dehumidifier will vary based on factors like the size of the space, the extent of the water damage, and the type of materials affected. However, here are some general best practices that apply to most scenarios:

How Many Commercial Dehumidifiers Do I Need?

While this may vary depending on the levels moisture present and the type of dehumidifiers you are using, here are some general rules for water removal requirements:

  • 600-800 sq. ft. – 75-99 PPD (AHAM)
  • 800-1,000 sq. ft. – 75-99 PPD (AHAM)
  • 1,000-1,200 sq. ft. – 100+ PPD (AHAM)
  • Over 1,200 sq. ft. you will need multiple air movers

The more saturated an environment is, the more likely you are to want multipole dehumidifiers, even if it is a smaller space. You will also want four to five air movers for every dehumidifier you use.

Commercial air movers help to circulate the air so that the dehumidifier is not cycling through the same air repeatedly.

Where Should I Place My Industrial Dehumidifier?

Commercial dehumidifiers should be placed in the center of the room or affected area. If you are using multiple dehumidifiers, place them at even intervals in the center of the space.

Commercial Dehumidifiers Placement Instructions

For the most effective moisture removal, use air movers to help circulate the air in the room. You will want four to five air movers for every industrial dehumidifier.

Commercial Dehumidifiers for Greenhouse Climate Control

Greenhouse growing is a complex undertaking with many factors to consider. These factors include the right amount of sunlight, regulated temperature levels, and balanced air moisture content.

Successful greenhouse growth requires having as much control over these factors as possible.

Balanced moisture content is important to produce healthy plants. Too much moisture can stunt plant growth. It can also promote fungi, mold, and mildew growth, but moisture balance is a difficult factor to control.

That’s why it’s important to use industrial dehumidifiers to keep the moisture content in balance.

To properly use a commercial dehumidifier in a greenhouse, it’s important to keep these factors in mind:

  • Number of Commercial Dehumidifiers Required: Small- to medium-sized greenhouses need two to four industrial dehumidifier units, and large greenhouses may require up to 10 units. Place them at equal distances around the greenhouse near windows and doors. At least one should be raised up slightly.
  • Operating Time of Industrial Dehumidifiers: You can operate commercial dehumidifiers all day long. But for best results and equipment longevity you’ll need to turn each unit off three times daily to empty the water tank. This also prevents the unit from overheating.
  • Supply of Fresh Air Flow: Open the greenhouse windows and doors each night for 15 minutes to allow a fresh supply of air. This also allows high temperatures to dissipate before the heat begins to rise again during the daylight hours.

Be sure to know the ideal growing conditions for your specific plants. Some plants thrive in high-humidity environments while others require low humidity.

Knowing this ahead of time will help you select the right dehumidifiers for your greenhouse operation.

Commercial Dehumidifiers for Mold Remediation

Commercial Dehumidifiers are often used in conjunction with air movers and air scrubbers during the course of a mold remediation job. They help to remove moisture from the air, which is typically the cause of mold growth in an area.

Best practices for using Industrial dehumidifiers for mold remediation will vary depending on the levels of moisture present, but for high levels of moisture and water, you can typically follow best practices for using commercial dehumidifiers for water damage restoration.

Often mold growth and water damage from a flood or other event go hand in hand.

Commercial Dehumidifiers for Indoor Climate Control

High condensation levels threaten the cleanliness and comfort levels in commercial buildings and facilities like business buildings, shopping centers, schools, and airports.

Over time, an accumulation of condensation can create the following problems:

  • Mold: Condensation can encourage mold growth. When mold takes hold in a building, it creates unpleasant smells and unleashes harmful spores. To prevent mold growth and to improve indoor climate and comfort levels, it is important to use professional dehumidifiers on an ongoing basis.
  • HVAC Problems: High condensation can cause moisture damage to the inner components of the HVAC system. Condensation also leads to rust, mold, and wear and tear on other HVAC system parts over time. Using commercial dehumidifiers to eliminate condensation can help protect and extend the life cycle of your HVAC system.
  • High Energy Consumption: When indoor building equipment is exposed to high moisture levels, it becomes difficult for them to operate at full capacity. This means they must work harder, which consumes more energy. Dehumidification systems for indoor climates can help recoup the costs of high energy bills and can help keep utility costs low.
  • Damaged Materials & Furnishings: High moisture levels can slowly deteriorate building materials like carpets, upholsteries, and wood surfaces. Property management dehumidifiers can preserve your building’s materials and furnishings for years to come.
