How High Humidity Damages Industries:

Humidity levels above 50% pose a danger to the industry. It has a detrimental influence on product quality and manufacturing efficiency. Moisture in the air causes harm to raw materials, machinery, and final items when it surpasses optimum levels. These problems cause production downtime, waste labor effort, and are costly to fix and correct. Occasionally, the damage is irreversible, resulting in PERMANENT defacement.

Due to excessive humidity levels, commercial warehouses, manufacturing, distribution, and service industries confront various difficulties. Let’s take a look at the most pressing issues.

Mold and hygiene issues: 

Bacteria, mold, and mildew thrive in high humidity conditions. There is a risk of health and safety risks to consumers and staff. To keep bacteria, mold, and mildew at bay, it is important to regulate relative humidity between 30% and 50%.

Corrosion:

Corrosion is the unintended yet harmful deterioration of a material or substance caused by its surroundings. In manufacturing contexts, humidity is critical for corroding metallic goods and machinery.

Rusting and other kinds of corrosion occur when materials react to moisture and air, compromising the machine’s integrity and function. Steel, for example, begins to corrode at merely 40 percent relative humidity and rapidly worsens, causing the entire device to fail.

Insect Infestation: 

Insects and bugs flourish in wet environments. If your workplace is infested with cockroaches, silverfish, centipedes, earwigs, and mosquitoes, it negatively influences staff health and productivity.

Structural damage: 

Increased moisture affects factories and warehouses’ concrete, pipes, floors, and storage areas, causing structural damage. Wooden buildings expand, shrink, and even decay as humidity levels fluctuate.

Quality control:

High humidity significantly influences the quality of the finished goods because it absorbs the extra moisture in the air. Excess humidity, for example, can impair the strength and flavor of food and medications and can even cause toxicity in the food and pharmaceutical industries. The product’s toxicity is due to viruses, bacteria, mold, fungus, and mites that flourish in humid environments.

Safety issues:

Condensation can form on manufacturing floors as a result of excessive humidity levels. As a result, the floors become slick, resulting in employee harm. Increased moisture in electric machinery can lower insulating resistance, resulting in short circuits and electric shock.

Damage to machinery:

Damage to equipment occurs as a result of a variety of reasons. The most significant of these is excessive wetness. High RH can quickly saturate electrical and electronic gear, posing a safety and quality concern.

The Only Solution:

The best commercial dehumidifier is the ultimate solution to these problems. Optimal industrial dehumidification provides appropriate humidity levels in enclosed spaces by combining moisture extraction with heat transfer and relative humidity at room temperature.

How do I choose a commercial dehumidifier? [Buyer’s Guide]

There are several variables to consider when selecting the best commercial dehumidifier for your office or business. Some of the most important aspects to consider are listed below.

Pump:

For added convenience, consider purchasing a commercial unit with a built-in pump. A built-in pump automatically pumps the collected water through a hose connected to a sink or nearby drainage hole. The moisture may be pushed out vertically because they’re automated. It’s almost illogical to buy an industrial dehumidifier without a built-in pump, given their customary enormous sizes and high weights, because you’d have to empty the water container manually. Thankfully, each item on this list includes a built-in pump.

Area of coverage:

The amount of space that a dehumidifier may cover is tremendous. These devices can cover regions of up to ten thousand cubic feet.

This is critical since the quantity of energy required to power your appliance will vary significantly depending on the product’s energy efficiency and the amount of space it must cover. Keep in mind that this grade varies a lot across brands and even between different models within the same brand.

The Dri-Eaz F413 Revolution LGR Dehumidifier, appropriate for spaces up to 7,000 square feet, has one of the most remarkable coverage areas on our list.

Humidity Level:

When purchasing business dehumidifiers, the humidity range in the surroundings must be considered. Because humidity levels are affected by temperature and seasons, the dehumidifier must endure harsh circumstances and reduce excessive humidity levels.

Level of noise:

Appliances that make a lot of noise are a pain to live with. Most models have a decibel rating of 50 or higher on average. It may be rather distracting and unpleasant at higher levels, especially during meetings or late at night. We recommend buying a model with two-speed fans, which will provide smooth and silent operation regardless of the humidity level. Quiet units are also energy efficient.

Before buying an appliance, test its noise level to ensure that it meets the manufacturer’s decibel specifications.

Pint capacity:

The pint capacity of a dehumidifier measures how much moisture it can remove. When a unit’s pint capacity is 250 PPD, that implies it can remove 250 pints of water from the environment per day. For industries, the greater the pint capacity, the better.

Drainage System:

Industrial operators will appreciate the simplicity of dehumidifiers with continuous drainage and a connected drain hose. They don’t have to constantly check to see if the water tank is full or empty. This feature prevents water leakage, puddles, and other safety concerns.

Temperature:

The interior temperature influences humidity level variations. Humidity is heavier in warmer temperatures than in cooler, dry conditions. In both cases, the commercial dehumidifier must be able to function effectively.

Material:

The material used in dehumidifiers is crucial to the unit’s longevity. When purchasing a dehumidifying system, businesses must ensure that the housing is built of high-quality steel and molded polyethylene.

Sensor for frost:

The frost sensor detects frost development in coils and switches off the dehumidifier, allowing the ice-covered coils to thaw and defrost. The machine automatically resumes when the defrost procedure is completed. So keep an eye out for a commercial model with a frost sensor and a hot gas bypass system.

Humidistat:

Humidistats integrated inside the device detect moisture levels in the air and assist in restoring and maintaining ideal humidity levels. As a result, make sure your industrial dehumidifier has a humidistat.

Timers:

A timer may be used to operate and maintain the humidity range without requiring significant input from the workers. If your industrial grade dehumidifier has a timer, it will undoubtedly save you time and work.

Filters:

The washable filter helps eliminate microorganisms, mold, and mildew at a low cost by reducing the expense of buying and replacing air filters.

Warranty:

Purchasing electrical equipment without a warranty is like flying without a parachute. While neither scenario is equally deadly, they are analogous in several ways. One of the first things to consider when purchasing a commercial dehumidifier for your office or business is the warranty that comes with the equipment. That way, you can rest easy knowing that if anything goes wrong with your equipment within the specified time frame, the business will be there to help you.

Additional features: 

You may want to think about adding a defrost system and an inbuilt humidistat to your refrigerator. The defrost mechanism is very beneficial since it lets the machine operate in extremely cold conditions by removing any ice build-up on the coil automatically. Also, look at the housing’s quality and the materials it’s made of, and see whether the package contains hoses and cables, so you don’t have to spend extra money on accessories.


Frequently Asked Questions 


  1. What is the purpose of a commercial dehumidifier?

    A commercial dehumidifier takes a dehumidifier's standard function of controlling humidity levels in a specific region and expands it up to a larger area, such as factories, warehouses, and retail. Unlike their domestic equivalents, commercial dehumidifiers can remove up to 150-250 pints of moisture from the air per day.
    If left uncontrolled, the humidity in a warehouse may be disastrous, resulting in damaged products as well as the growth of mold and mildew. It is beneficial to remove it with a device such as a professional dehumidifier to maintain your area running as intended and free of health hazards.

  2. Do commercial dehumidifiers last longer?

    Commercial dehumidifiers are more expensive than household dehumidifiers because they are more durable materials and last longer. Poor insulation and a lack of a central air system can result in extreme temperatures, excessive humidity, mold, and mildew.

  3. What Are the Uses of Commercial Dehumidifiers?

    Huge spaces, such as warehouses, large basements, arenas, or any other large area that may be impacted by excess moisture, benefit from commercial dehumidifiers. Though they are more heavy-duty, they are also suitable for residential use, particularly if you have a basement, garage, or even a crawl area that needs moisture control to avoid concerns like mold or mildew. They are less appealing for residential usage since they are more heavy-duty, but buying one for a more inconspicuous location, such as an unfinished basement or garage, would be ideal for a commercial dehumidifier.

  4. Are commercial dehumidifiers loud?

    Single-room dehumidifiers are quieter than commercial-grade dehumidifiers. Fortunately, they're usually found in basements, crawl spaces, and industrial environments, where noise isn't an issue.

  5. How long does it take for an industrial dehumidifier to work?

    Commercial dehumidifiers, on average, take between 24 and 48 hours to dry out a room, depending on the size of the space. Consumer units might take anything from two days to a week to arrive. Test areas using a moisture meter to verify they are totally dry.

  6. What does Aham stand for a dehumidifier?

    AHAM and saturation determine the dehumidifier testing conditions. The American Home and Appliance Manufacturers Association (AHAM) is a trade association that represents home and appliance manufacturers in the United States. The abbreviation is frequently used because the organization suggests precise testing conditions of 60% humidity and 80 degrees Fahrenheit.
