Chapter 1: How to Know Which Dehumidifiers You Should Use for Restoration Projects

Dehumidifiers play an important role in water restoration jobs. They offer an easy and efficient way to reduce the moisture content in the air to offer the balanced drying system needed to safely and effectively perform a water restoration job on a property.

In terms of a water damage restoration dehumidifier, Aer Industries offers two types: conventional dehumidifiers, and low grain refrigerant dehumidifiers, also known as LGR dehumidifiers.

two types of dehumidifiers

The goal of this dehumidifier buying guide is to you choose the commercial dehumidifier for your job.

What Is a Conventional Dehumidifier?

A conventional dehumidifier is considered a basic industrial portable dehumidifier. It condenses water onto its cold coils to effectively remove the water from the air. Most of the water evaporates and the rest goes out the exhaust of the machine.

These water damage dehumidifiers are self-contained units that work well in high humidity, and they can remove water at about 55 grains per pound.

Aer Industries is a leading dehumidifier supplier, and we offer several different conventional dehumidifiers for sale:

1. BlueDri™ BD-130 Industrial Dehumidifier

If you have the funds, it’s a good idea to have one or two of these portable commercial dehumidifiers on hand to act as backups.

How to Utilize Low Grain Refrigerant Dehumidifiers

Low grain refrigerant dehumidifiers are also called LGR dehumidifiers. Water restoration professionals typically buy LGR dehumidifiers because they have capabilities that the conventional refrigerant dehumidifiers do not have. The LGR is a heavy-duty dehumidifier machine that can remove water below 55 grains per pound (GPP).

If you’re looking for an LGR dehumidifier for sale, Aer Industries has three models:

low grain dehumidifiers

An LGR dehumidifier is a great industrial air dehumidifier, but it is the most powerful when used in conjunction with an air mover and an air scrubber. Aer Industries wants you to have the proper tools for the job, so we offer industrial dehumidifier packs that combine these items to offer you a discount on the equipment you need.

Placement Guidelines

One of the ways to determine the heavy-duty dehumidifier to use is to look at the square footage of the space needing restoration. You also have to take into consideration the saturation level, the temperature and the humidity of the room.

heavy duty humidifier

Some general figures for choosing the compact industrial dehumidifier are:

  • 600 to 800 sq. ft. space: 75-99 PPD AHAM
  • 800 to 1,000 sq. ft. space: 57-99 PPD AHAM
  • 1,000 to 1,200 sq. ft. space: 100+ PPD AHAM
  • 1,200+ sq. ft. space: Use more than one dehumidifier

Determining Correct Placement of Your Dehumidifiers

Dehumidifiers need to be placed properly to ensure they work efficiently and effectively. Keep in mind the following for positioning your dehumidifiers:

  • It’s important to place your property restoration dehumidifier in the center of the room for maximum efficiency.
  • If you have to use two or more dehumidifier systems, you should stagger them so there is an equal amount of space between them and distance from the walls.
  • Always place industrial air dehumidifiers facing away from each other so they are drying separate areas.

The initial placement of your heavy-duty dehumidifier machine is essential to quickly getting the evaporation process started, but you may need to make adjustments as the property dries over time. Aer Industries, your commercial dehumidifier dealer, is available to answer any questions you may have about proper placement when you buy commercial dehumidifiers.

Dehumidifier Effectiveness

No matter which model you choose of the industrial dehumidifiers for sale, you will see the terms AHAM and saturation. These terms are important factors in knowing how effective a dehumidifier will be. AHAM and saturation must be considered when you’re choosing an industrial size dehumidifier, or you’ll end up with a unit that’s ineffective.

aham saturation dehumidifier

AHAM Versus Saturation

What is the difference between these two terms, and what do they really mean?


AHAM stands for the Association of Home Appliance Manufacturers, which is the company that established the testing conditions and therefore the standard. AHAM ratings refer to “average” conditions, which means a humidity level of 60 percent and a temperature of 80 degrees Fahrenheit. Water damage professionals use the AHAM rating to know how a dehumidifier will operate in average conditions.


Saturation measures the maximum amount of moisture an industrial size dehumidifier can extract in one day — in extreme conditions. Saturation measurements are taken at 90 percent humidity and 90 degrees Fahrenheit.

These conditions are more extreme than what will usually be seen in the water restoration field, so the saturation level just gives you an idea of the maximum performance you can expect from the dehumidifier you choose. In reality, industrial dehumidifier machines will be able to remove far more water in the field.

How to Compare Commercial Dehumidifier Machines

When you encounter a dehumidifier sale, you may find a larger water damage restoration dehumidifier is only measured at AHAM or only measured at saturation. Without having both measurements on every model, how can you compare the two to choose the model?

Dehumidifiers can remove more water in saturation conditions than in AHAM conditions. As a quick translation, this means that an AHAM measurement of 70 PPD is more effective than another model with a saturation measurement of 80 PPD. For comparison purposes, there is a general rule you can apply in this situation.

dehumidifiers water

A dehumidifier extracts about half as much moisture in a day in AHAM conditions as it does in saturation conditions. For example, the B-Air® Vantage VG-1500 commercial dehumidifier removes 76 PPD in AHAM conditions and 150 PPD in saturation conditions.

Aer Industries offers products from some of the industrial dehumidifier manufacturers, and our experts can answer any questions you may have when it comes to AHAM and saturation.

Frequently Asked Questions About Commercial Dehumidifiers:

Q: How do I clean my commercial dehumidifier?

A: You will need to change your dehumidifier’s air filter as needed – typically between jobs. You will want to clean the condensing coils as well, but less frequently; every 3-6 months is fine for most equipment. For desiccant dehumidifiers, you may need to clean out the desiccant wheel as well.

Q: When do I need to use an LGR dehumidifier instead of a conventional (refrigerant) one?

A: Conventional (refrigerant) dehumidifiers are great for smaller water damage restoration projects or as backup/additional dehumidifiers on bigger projects. For larger restoration jobs, LGR (low grain refrigerant) dehumidifiers are often needed due to the larger amounts of moisture in the environment.

Q: Can dehumidifiers be left running overnight?

A: Commercial restoration dehumidifiers from Aer Industries, including B-Air® and BlueDriTM brand equipment, can be left running overnight and for days at a time if necessary. If you use another brand of equipment, check your guide from the manufacturer on usage recommendations.
