Harmful Effects Of High Humidity In Industries

High humidity is a severe threat to industries. It negatively impacts production efficiency and product quality. When the air’s moisture exceeds ideal levels, it damages raw materials, machinery, and finished goods. These issues result in production downtime, wasted workforce effort, and is quite expensive to repair and rectify. Sometimes the harm becomes irreparable, resulting in PERMANENT defacement.

Commercial warehouses, manufacturing, distribution, and service industries face several issues due to high humidity levels. Let’s look at the most relevant problems here.

🗜️ Corrosion: A destructive yet unintentional degradation of a material or substance due to its environmental condition is corrosion. Humidity plays an essential role in corroding metallic products and machinery in manufacturing environments.

When materials react to moisture and air, it results in rusting and other forms of corrosion that affect the machine’s integrity and performance. For metals such as steel, the corrosion starts at just 40% RH and rises rapidly, damaging the entire unit.

🎍 Mold and hygiene problems: High humidity environments are the perfect breeding ground for bacteria, mold, and mildew. This can be quite hazardous to consumer and employee health and safety. The RH levels need to be kept between 30-50% to contain the growth of bacteria, mold, and mildew.

🏛️ Structural damage: Increased moisture damages concrete, pipelines, flooring, and storage spaces in factories and warehouses. Fluctuating humidity levels cause wooden structures to expand, contract, and even rot.

🦟 Pest Infestation: Some several insects and bugs thrive in moist conditions. If cockroaches, silverfish, centipedes, earwigs, and mosquitoes infest your work environment, it negatively impacts employee health and productivity.

⚙️ Damage to machinery: Equipment damage happens due to several factors. The most important of them are high moisture levels. High RH can cause electrical and electronic machinery to saturate quickly, creating safety and quality risks.

✔️ Quality control: High humidity level dramatically impacts the quality of the end products, absorbing the air’s excessive moisture. For example, in the food or pharmaceutical industry, excess humidity can reduce the potency and taste of food items and medicines, sometimes even creating toxicity. The product’s toxicity is attributed to the viruses, bacteria, mold, fungi, and mites that thrive in humid conditions.

🔒 Safety issues: Condensation can occur on factory floors due to high humidity levels. This causes the floors to become slippery and result in injury to employees. In electric machinery, increased moisture can reduce insulation resistance leading to short circuit and electric shock issues.

Dehumidification is the savior

Important factors to keep in mind while purchasing a commercial dehumidifier

Investing in the dehumidifiers’ commercial model is the best decision you can make to protect your business space from humidity issues. Commercial grade dehumidifiers face larger humidity extraction challenges when compared with household ones. They need to be rugged, reliable, bigger in size, durable, and portable, with the capability to operate optimally at a broader range of temperatures.

Dehumidifier commercial units must be carefully inspected, and evaluated, for two primary parameters, viz., energy efficiency and optimal performance. The following are significant factors to keep in mind while purchasing a commercial grade dehumidifier.

Square feet area– The commercial area to be dehumidified must be measured before looking for an industrial dehumidifier. As each model caters to a different area specification, you must ensure you choose the right unit.

Pint capacity – The moisture removal capacity of a dehumidifier is known as the pint capacity. When the pint capacity is 250 PPD, it means that the unit can remove 250 pints of water per day from the atmosphere. The larger the pint capacity, the better it is for industries.

Humidity level – The humidity range in the environment must be considered while buying commercial dehumidifiers. As temperature and seasons play a vital role in humidity levels, the dehumidifier must withstand tough conditions and reduce high humidity levels.

Drainage facilityDehumidifiers with continuous drainage facility and an attached drain hose offer utmost convenience to industrial operators. They need not keep checking if the water tank is full or to empty the tank. This feature helps avoid water spillage, puddle, and safety issues.

Indoor temperature – The indoor temperature plays a significant role in humidity level fluctuations. Warmer temperatures are heavier on humidity compared to colder dry temperatures. The commercial dehumidifier must be able to operate efficiently in both conditions.

Noise level – High noise levels cause auditory problems to industrial workers. However, since commercial dehumidifiers are robust and high capacity, the noise levels are also relatively high. Special care must be taken to choose the model with the lowest possible decibel levels.

Housing material- Dehumidifier material plays a critical role in the durability of the unit. While buying the dehumidifying system, industries must inspect if the housing material is made up of good quality steel and molded polyethylene material.

Frost sensor – Detecting frost buildup in coils, the frost sensor turns off the dehumidifier and lets the ice-covered coils warm and defrost. Once the defrost process is done, the machine automatically restarts. So look out for a commercial variant with a suitable frost sensor and hot gas bypass system.

Humidistat – Inbuilt humidistats not only monitor the moisture levels in the air, but it also helps restore and maintain optimum humidity levels. Hence ensure your commercial dehumidifier comes with a humidistat.

Timers – Operating and maintaining the humidity range without much workforce interaction is possible with a timer. If your industrial grade dehumidifier comes with a timer, it will surely optimize your effort and time.

Washable filters – Saving the cost involved in buying and replacing the air filters, the washable filter helps get rid of the microbes, mold, and mildew cost-effectively.

Apart from all the factors mentioned above, industries need to check for automatic reset and automatic restart feature, caster and semi pneumatic wheels, and digital controls, to ensure convenience, and to save cost, time, and effort. Make sure you compare and contrast the features of different commercial models before settling for your best buy.

Features of an industrial dehumidifier that you don’t find in a household dehumidifier

If you live or work in a humid environment, then you need a dehumidifier to lower and optimize the relative humidity. Considering the size of your space, the purpose of utilization, humidity level, risk factor, water seepage and chemical level, you must decide between choosing a residential or industrial dehumidifier.

⚈ Household dehumidifiers are usually more compact, with low capacity, light load, and volume, compared to industrial dehumidifiers.
⚈ They are visually appealing and ideal for confined spaces such as the basement, crawl space, attic, etc.
⚈ Made of low duty components, the household dehumidifiers are easily portable and less noisy than their commercial counterparts.
⚈ They also easily blend in with your home decor, adding a sense of coziness and style to your living space.

✔️ On the other hand, industrial dehumidifiers are of larger capacities with a more robust and more durable design. They are rugged and are built to last in larger areas with extreme conditions.
✔️ They offer greater installation flexibility as they work in highly demanding environments.
✔️ Built to last longer than residential dehumidifiers, the industrial variants are made for heavy-duty use.
✔️ They are ideal for industrial environments that operate on a wide temperature range, non-stop usage, corrosion, resistance, and higher airflow.

However, there are certainly exceptional cases where commercial dehumidifiers can be used in residential settings. Indoor pool, spas, and laundry rooms are examples where commercial dehumidifiers can help, as there are large water bodies and too much water usage.
Based on your need, space size, and pint capacity, you can choose between a residential or an industrial dehumidifier.

Remove excess moisture in commercial spaces using these 3 tricks

5 Expert tips to increase the durability of an industrial-grade dehumidifier

A typical dehumidifier lasts up to 10 years. If you want to increase the durability and longevity of the commercial dehumidifier, you must take care of the unit properly. Here are 5 simple tips from experts to boost the durability of your commercial grade dehumidifier.

🌡️ Mind the temperature:
Humidity levels tend to fluctuate throughout the year with temperature and seasonal variations. During colder climates, the air is relatively drier with lesser humidity. But in warm or hot temperatures, the air is super humid. The efficiency of the dehumidifier increases and decreases in warm and cold climates respectively. Hence you must operate the dehumidifier based on the temperature and RH requirements.

To increase the lifespan of the industrial dehumidifier, it must not be operated below 60 degrees Fahrenheit. As the water removed from the air can freeze while condensing on the cooling coils, it can damage the unit badly.

The best way to manage durability is to invest in a commercial dehumidifier with a built-in humidistat and auto-defrost capability. Automatic on and off feature also helps commercial dehumidifiers to save energy by automatically switching off the unit when the temperature falls below recommended levels.

🧼 Clean regularly:
A thorough cleaning at least once a month is imperative to keep the dehumidifier in optimal running condition. While dehumidifying the commercial space, these units gather mold, mildew, bacteria, germs, and other particles.

Before getting into the cleaning process, ensure your safety by turning off and unplugging the system. Mind you, as industrial power ranges can be FATAL. Then wipe the outer housing using a damp cloth without spraying water or cleaning solvents on the unit. Remember to gently scrub and rinse the reservoir, air filter, hose drain, and the bucket filter.

📆 Replace air filters and power cord:
The air filters in the dehumidifier helps remove dust particles from the incoming air before it passes through the coils. These filters must be washed frequently and replaced at scheduled timing to avoid clogs and facilitate better air circulation. They are not very expensive and can be purchased from sellers who sell HVAC filters.

Inspect your power cord regularly. Never use a damaged cord as it will result in fire hazards, electric shocks, and safety risks. If you find your cord battered, immediately replace it with a cable of the same type and amperage. Therefore periodic replacement of air filters and power cord play a significant role in the longevity of the dehumidifier unit.

🔍 Check for wear and tear:
As part of the weekly maintenance, commercial dehumidifiers must be checked for corrosion, rusts, and other wear and tear. Inefficiencies in operation, accidents, ageing, and other environmental factors contribute to the deterioration of the dehumidifier units. Regular checking and repairing will help increase the lifespan of the commercial dehumidifier.

🧑‍🏭 Train employees:
If the operators are not trained properly, they will not be able to run the dehumidifier optimally. They will cause equipment wear and tear, performance failures, and injuries. Industry regulators stipulate that only well trained and certified employees should handle and manage heavy duty dehumidifiers.

Once you follow all the 5 expert tips delved upon above, the durability of the commercial dehumidifier will definitely increase.

FAQ Section

1. What to do when an industrial dehumidifier is not working?

If the industrial dehumidifier is not working we should contact the customer service / an HVAC professional to investigate the problems.

2. What happens if your most trusted dehumidifier starts acting funny, or worse, stops working?

The first step is not to panic. The second step is to investigate the issue. The final step is to troubleshoot the dehumidifier as quickly as possible.

The common issues in a dehumidifier are as follows.
1. Overflow or leaks
2. Freezing up
3. Bad odor
4. Increased noise
5. Too much head pressure
6. Defective humidity sensor
7. No outward airflow
8. Low or no water level
9. Stops functioning altogether

Irrespective of the issue, follow the steps below to troubleshoot your unit.
⚠️ Check if the main power panel is switched on
⚠️ Ensure that the circuit breaker and fuse is not tripped or blown
⚠️ Switch on all the controls
⚠️ Set the humidistat between 50% to 60% relative humidity
⚠️ Check if the fans are running
⚠️ Empty the water tray
⚠️ Clean the air filter
⚠️ Check for any disconnections or cuts in the wiring

If you are STILL not able to make head or tail of it, immediately call your dehumidifier service professional to sort out the issues in a jiffy. It is a known fact that dehumidifiers make a lot of noise. The compressor, exhaust fans, and condensate pumps are vital contributors to the sound levels. On average, a home dehumidifier noise is rated around 55-60 dB, which is about the same as regular human speech sound level.

Some crawl space dehumidifiers tend to get noisier when the fan motor or compressor mounting brackets or screws become loose. This improper connection causes the fan or compressor to vibrate and become noisy. So whenever you feel that the dehumidifier in your crawl space has started becoming noisy, first unplug the dehumidifier and tighten any loose components. Even after tightening, if the noise increases, you may have to replace the fan or compressor.

3. What is a boat dehumidifier?

Boats, yachts, ships, and marine ecosystem buildings located on the seaside and riverside suffer from the ill effects of high humidity. This condition causes significant discomfort to the people travelling or working in these areas. The moisture in the air causes wood rot, and damages furnishings, appliances, and other metallic objects in the boat. It creates musty odor, mold and mildew growth, rusts machinery and metal furnishing, and dampens walls.

Worsening things even further, humidity gives allergies and sinus infections to travellers, making them irritable. It even brings mosquitoes, insects, and other pests into the interiors of the boat.

The only solution for this moisture problem is to use an effective boat dehumidifier that is built to withstand challenging marine conditions. It helps keep the boat dry, clean, and warm. Desiccant, compressor, or thermoelectric types of dehumidifiers can be used in the boat according to the need and preference. Whatever the choice is, the unit must be waterproof, compact, portable, and comprise of rust-free components. It must also withstand long periods of non-usage.

The boat dehumidifier must be chosen based on two important criteria, namely weather conditions and water quality. The dehumidifier for saltwater conditions will not be effective in freshwater boats. It needs to have safety features to prevent electrical incidents and corrosion damage. Built-in humidistat would be a great power saver that can help the unit switch off when the humidity is ideal and resume dehumidifying once the level increases.

A condensate pump with a vent or a long hose that can be release the collected moisture even when it is unattended would be an added advantage. Since the boats are always on the move, the boat dehumidifier must be compact in size with a fastening feature that prevents the unit from rolling away.

4. What is a crawl space dehumidifier?

Crawl spaces at home or in commercial buildings are MOST vulnerable to humidity problems, as they are not easy to ventilate. When humidity exceeds ideal levels, or when there is water seepage or flooding, crawl spaces are the worst damaged spots in a building. It becomes a hotspot for pest infestation, mold and mildew growth, wood rot, product decay, and disease-causing allergens.

High moisture levels in whole house damage the structural integrity of the building causing breakage, corrosion, and rust. Slowly the building’s basement gets damaged and might collapse at any moment.

The only viable way to save your building from these hazardous conditions is by dehumidifying your crawl space. There are compact, powerful crawlspace dehumidifiers available in the market that dries out moisture and keeps your basement and crawl space in perfect condition.

Over 40% of the air on your first-floor seeps in from your crawl space and basement. Insects and pests that breed in damp basement areas slowly proliferate into working areas. The air quality in the crawl space profoundly impacts air quality in the building. It affects the machinery, appliances, furniture, walls, and every other living and non-living entity in the rest of the building.

While shopping for a crawl space dehumidifier, you must ensure that the models are built with the following features. They must have good pint capacity, simple ducting, inbuilt humidistat, digital control panel, condensate pump, low-temperature operation, hot gas bypass, automatic restart and defrost systems.

These features enable the quick melting of frost buildup and help the unit can resume dehumidifying optimally. You should check the energy efficiency of the dehumidifier before purchasing one for your confined space. They must be built to last and reliable enough to withstand flooding and water seepage, and perform well in tough conditions. They also need horizontal configurations since the basement and crawl space have low clearances.

 Check out the warranty on parts and labor before making your buying decision.
Though small enough to easily fit in crawl spaces , these units must have high power and capacity to eliminate as much as 70-90 pints of water per day from areas as large as 2,500-3,000 square feet.
