Excess moisture in the environment can have detrimental effects on equipment, building material and the health of individuals in the area. Overly moist environments create the ideal setting for mold and mildew to grow, causing respiratory problems for those in the area and damage to the facility.

In order to combat rising humidity, an effective industrial grade dehumidifier is the optimal solution. Find out how the device works and the many ways it can benefit a building or construction site below.

How an Industrial Grade Dehumidifier Works

Industrial dehumidifiers, also known as commercial dehumidifiers, work by using a fan to draw air across the coils inside the unit. As the warm air is drawn across the coils cooled by a refrigerant, moisture is removed from the air and held within the dehumidifier as condensation. The condensation is collected in a bucket, which then can be pumped away from the unit into a drain or be emptied when full.

This process of removing excess moisture from the air helps to maintain a balanced environment free from mildew, metal corrosion, or odors that humidity can cause.

What to look for in a Commercial Dehumidifier

Not all dehumidifiers are created equal. When searching for the ideal unit, make sure to pay attention to these important specs.

Max Removal. This refers to how much moisture the unit removes from the air in a 24-hour period. The max removal is typically measured in pints, and the amount you’ll need will depend on the humidity levels in the room.

Room size. The square footage of the room will also influence how much drying power you need. A smaller room typically warrants a less powerful dehumidifier, while a larger space requires a more heavy-duty machine.

Usability. A dehumidifier that is easy to use makes all the difference. Look for a unit with a simple control panel and straightforward settings. This way, you reduce the chances of confusion and ensure the machine is running according to the settings you specify.

Condensation Hose. A dehumidifier collects excess moisture, and that needs to be let out in some way. If your unit comes with a condensation hose that can easily be routed through a drain, then there’s no need to worry about emptying out a pan that fills up. So simplify the process by selecting a unit with this helpful addition.

Does an Industrial Grade Dehumidifier Use a lot of Electricity?

In light of the impactful benefits the dehumidifier provides, you may be thinking that the machine requires copious amounts of energy. The reality is that these units are built to be energy efficient and use less energy than a hair dryer.

Industrial Grade Dehumidifier Applications

Now that we’ve covered how these units operate, let’s discuss where dehumidifiers can be put to use.

Dehumidifiers can be used for prevention or restoration after excess moisture has already damaged a space. These versatile units can be used in a wide range of applications, including:

From businesses to offices to job sites and more, dehumidifiers keep humidity in check. Read on to find out where to get the right dehumidifier for your location.

Humidity doesn't just make you uncomfortable but also causes problems and health hazards at every level of the building. Humid weather exacerbates moisture problems and often causes concerns in crawl spaces above the room and below. Moisture from the ground works with moisture from the humid air to generate condensation on the walls and other surfaces to create muggy feels and smells in the atmosphere.

In turn this can translate into mold and mildew issues not only on walls and windows but also on water pipes, toilet tanks and floors. Mold and mildew can get into wood flooring or carpets and may be hard to completely remove. Humid air can build up in walls which might attract mildew. Interior and exterior paint tends to bubble and peel under extended humid conditions. When a building goes unprotected from the humidity and outdoor elements then there is a chance for many adverse issues both hidden and visible to start destroying your building. Using air conditioning can reduce humidity while reducing temperature if done correctly.

Humidity also wreaks havoc on clothes, food and other stored items such as office paper. Dry foods can draw in moisture and quickly go stale if humidity exceeds 60%. Cansmay rust and leak in humid weather as well. If humidity is an issue, keep stored food in an air-conditioned space.

Have the right emergency plan in place to help fight conditions such as these. If you have air-conditioning problems or the need for temporary air please give us a call and we will be happy to let you know what Portable Air can do to help keep you and your building cool.

The effects of moisture inside a building under construction can become a serious problem for contractors as well as a danger to future occupants. Unless this moisture is reduced to acceptable tolerances, a contractor may be confronted with a variety of problems. They may be as small as construction schedule delays or as large as flooring failures resulting from elevated moisture content in a concrete slab.

In an attempt to manage moisture, contractors typically use one of two methods to dry building materials during the construction process: desiccant dehumidifiers or heat. While there has been much debate as to the most effective technology for construction dying, scientific fact cannot be argued.

If one were to evaluate a desiccant dehumidifier and heater with respect to their moisture removal capabilities, a heater does not compare. To simply introduce heat into a building space will not remove the actual moisture that is present in the air.

Heat-Only Systems can temporarily reduce relative humidity but it does not remove moisture from the air and, most importantly, it does not reduce vapor pressure. In fact, heating the space with particular types of heat-only systems, such as direct-fired heaters powered by combustibles such as propane or natural gas, will actually add moisture to a space. Heaters are also very ineffective at maintaining conditions and eliminating mold growth.

Desiccant Dehumidifiers used for construction drying are different from those used in permanent installations for commercial buildings, they are designed to withstand the construction environment and provide the drying capacity required to establish and maintain proper environmental conditions. In direct comparison to a heating system, as air passes through the desiccant material inside of a dehumidifier, the moisture is literally assumed by the desiccant material and consequently removed from the airstream. Because there is a direct correlation between moisture content and vapor pressure, by removing moisture from the airstream, one simultaneously lowers the vapor pressure of that airstream. For this reason, desiccant dehumidifiers are very effective at reducing relative humidity and maintaining conditions and eliminating mold growth.

For most professional trade organizations there is no longer debate as to which technology is most effective for drying building materials. For example, the Northwest Wall and Ceiling Bureau, which serves general contractors, material manufacturers, dealers as well as labor groups, in a statement about wallboard in weighed in technical bulletin #303, said "Cold damp weather contributes to joint bond failure, delayed shrinkage, ridging, nail pops, joint flashing and board sagging. Proper temperature and humidity levels (environmental conditions) are important factors in achieving satisfactory results. Some sources of temporary heat will cause high humidity. The NWCB recommends a desiccant dehumidification system for best results in joint finishing and final decoration of gypsum wallboard."

A common misconception is that the building's permanent HVAC system can address moisture problems during the construction process. The building's permanent HVAC system is engineered for temperature control with much less attention paid to moisture removal. This system does not have the capacity to remove elevated ambient moisture. Operating the building's HVAC system too early can also spread mold spores.

In summary: moisture control = mold control

Moisture can wreak havoc on a construction site affecting all types of building materials. By factually comparing the two most common technologies used for construction drying applications, it is evident that heat alone cannot reduct the moisture content or vapor pressure that is present in a construction space.

As the construction industry has evolved, and through practical application as well as scientific fact, it is evident that a desiccant dehumidifier is much more effective at drying construction materials than a heater. Because a desiccant dehumidifier reduces both humidity and vapor pressure, it is the most effective method for providing a construction environment where materials dry at an accelerated pace and the potential for mold growth is considerably decreased.


Most people know that excessive humidity can make them feel even hotter during the warmer months of the year. It comes as no surprise, then, that it has a major impact on the effectiveness of air conditioning systems. What people don't often realize is that humidity has an effect on heating systems as well. When the humidity in a space is too high or low, achieving optimal indoor comfort is easier said than done. Portable Air offers various models of temporary air conditioning as well as dehumidifiers that keep relative humidity levels in check.

How Humidity Levels Affect Air Conditioning

Air conditioners cool spaces by removing heat and moisture from the air. When humidity levels are excessive, they need to work a lot harder. If the equipment doesn't have sufficient cooling capacity, it may be unable to cope with extreme humidity. As a result, the space may never feel truly comfortable. A few common signs of high indoor humidity include:

Air Conditioning Systems & Humidity

In theory, an air conditioning system should be able to remove moisture from the air. When the humidity levels spike, however, most systems can't cope. Humidity affects air conditioning negatively because it cancels out the cooling effect. When the humidity is too high, your home/office will feel warmer than it actually is. You'll have to keep your air conditioning system running but won't derive nearly as many benefits from using it. In other words, you'll pay more to cool your home but won't actually cool it that effectively.

Air Conditioning & Cooling Capacity

People often assume that the larger and more powerful an air conditioner is, the more effectively it can cool a space. That's not necessarily true. If your air conditioner's capacity is much larger than needed, it won't be able to remove moisture as effectively. In turn, the spaces that you are looking to control, humidity levels will remain high. This is because more powerful air conditioners don't need to run as much, so they don't get a chance to remove as much moisture from the air. This is why it's crucial to size the correct unit to meet each need.

Dehumidifiers

The single best way to content with humidity when trying to cool a space is by having a dehumidifier installed. This simple appliance will pull moisture from the air, trapping the condensation, before dispersing the condensation out of the area. Dehumidifiers can be paired with air conditioning systems, which allows you to adjust the temperature and humidity level of the space in one fell swoop. When humidity levels are kept in check inside the space you are controlling during the summer, air conditioners are able to do their jobs much more effectively. You will notice that you feel cooler and more refreshed under these conditions.

How Humidity Affects Heating

If high humidity causes problems while trying to cool a space during the summer, low humidity wreaks a special havoc of its own during the winder. Humidity affects heating, but it does so in the opposite way. Humidity levels drop dramatically during the winter. In turn, relative humidity levels inside the space drop as well. In fact, they can drop so much that they can make space feel a lot cooler than it actually is.
Ideally, the thermostat in a home should be set between 71 and 77 degrees. This is optimal in terms of comfort and cost. However, this range won't produce truly comfortable results if humidity levels fall below 50 percent. When that happens, the apparent temperature in a space, which is how warm or cool a space actually feels, will be too low.

Your essential guide to drying rooms and buildings after a flood disaster.

The rain lashes down and drains block with fallen leaves and silt. The flood waters rise and search for new destinations. Houses, businesses, shops, offices, schools – the flood water does not discriminate between building types, only what ‘level’ they are at. Although these days flooding can arise at any time of year it is still a particular problem in autumn. Buildings affected can be anything from a bit damp to massively damaged by flood water. Here we provide our top tips for drying outbuildings and rooms affected by flooding. These top tips are as useful for drying up after a burst pipe, or bath overflow as they are for a rainwater flood, and should help you get dry in quick time.

1. If insured, discuss your claim and drying requirements with your insurer. They may hire a contractor to do the drying for you, in which case you can concentrate your attention on saving your contents and making sure that those you are responsible for are accommodated somewhere else. If it is a small drying job, perhaps one that is uninsured, or one that is not worth claiming for then the next 9 top tips are good to go, so long as you can establish that it is safe to do so by first consulting an electrician and perhaps a plumber.

2. Whats wet? No, it’s not a stupid question but the answer will affect how you dry the building and what equipment you use.

Say you have a traditional type constructed building with drywall and concrete floors, complete with wet carpets, then what you are looking at is potentially using a wet vac (to suck up any remaining flood water from your carpet), a carpet dryer fan to blow air under the carpet, dehumidifier and a radiant heater.

If you have a modern solid floor with tiles, timber or laminate flooring, then the chances are that it has been laid with an insulation layer which is saturated and needs to be dried before it can again be an effective insulating layer. For this, you will need a restorative drying unit (to suck water out from the insulation layer under the floor), a dehumidifier and a radiant heater.

3. Use as big a dehumidifier as you can afford. Basically, a little domestic plastic cased machine will not be up to it. You will need a big mobile dehumidifier – consider 30 ltr/day extraction rate as the bare minimum for drying a flood-damaged small room. Bigger is better and quicker. More than one room to dry? Then consider using extra dehumidifiers.

4. When using a dehumidifier make sure to minimise air ingress into the building. Close all doors and windows and trickle vents (if you have them). The idea here is that by keeping the building air sealed, that the air in the building can be made as dry as possible with the dehumidifier, without giving it the extra burden of drying extra air from outside.

5. Ensure the dehumidifier is positioned so that it can treat the air without any obstructions. Placement in the middle of the room is best. If you have a large room and a number of dehumidifiers working simultaneously, spread them evenly in the room and away from walls.

6. Use portable radiant heaters for heating up surfaces, such as plasterwork. Warm walls will evaporate water far quicker than cold walls. Either use conventional portable radiant heaters or use radiant masonry drying panels. Don’t put them too close to the wall otherwise, you will get a hot spot, but do place the distance away so that a greater area is gently warmed.

7. Add extra heat. Radiant heaters when used will also in time warm up the air in the building, but it is still cold put in electric space heaters in to raise the air temperature. Don’t use direct fired oil or gas heaters for this purpose as they will deplete the oxygen in the building. If you need more heating power, beyond what the mains supply to the building can safely provide via electric heaters, then use indirect fired oil or gas heating, with the heater located outside and warm air ducted in, ideally on a recirculation system so that heat is not wasted to the outside. Ideally, the building air temperature needs to get to at least 20°C. The warmer the air is the more moisture it can hold, the more water will evaporate from surfaces, and the more efficiently the dehumidifier(s) will work.

8. Work out what happens with the condensate collected by the dehumidifier. If it collects in a tank, remember to frequently empty the tank. If you do not do this the dehumidifier will stop to prevent it spilling the condensate on to the floor. If it has a continuous drainage arrangement make sure that it can flow by gravity to a suitable drain. If the dehumidifier has a condensate drain that is great because it means that you can get the condensate to a drain more or less anywhere within reach of the hose that you attach to the dehumidifier and means you can leave the machine to work for long periods.

9. Consider putting air circulator fans into the building. If there is not enough air movement from the various machines in the building, the dehumidifiers, heaters, carpet dryers etc., you may discover that some areas are holding air pockets which are being left by the general air circulation. In this situation use fans to move the air in these areas.

10. Use a moisture meter to track drying progress. With active drying, there is a danger that walls and floors appear to be dry when they are still damp under the surface. 2 pin or 4 pin moisture meters can be purchased for as little as $50 dollars and they tell you what is happening in the wall rather than what is happening on the surface. If you don’t get this right, you might think your building is dry and as soon as you remove the dehumidifiers and drop the heat to normal levels, damp will reappear. Also use feel to determine how the building is drying. Drying of walls will start at the top of the wall and dry towards the base. As you run your hand over what appears to be a drywall, top to bottom you will probably notice the temperature of the wall cool, part way down. This will be roughly where the wall has dried down to.

These Building Drying Top 10 Tips are designed to give a brief overview of the challenge drying a building or perhaps a room. The Guidance and standards for drying flood-damaged buildings provides a really comprehensive guide to the subject and has much more information.

Before Hurricane Harvey was just like any other hurricane scare in the past that I've ever experienced meaning I'm going to prepare but I won't overdo it. It's probably going to miss us and if it does, it won't cause much havoc. I've lived through a lot of scares but never a direct hit. I was hoping I could still work and days would go about as normal. I remember it was the last day my neighborhood clubhouse pool was going to be open so I even stopped at Toys r us and picked up an inner tube my daughter could swim better in the pool in. I didn't start to get worried until the day before and I stayed glued to the tv tracking it. I kept seeing that the intensity would be stronger than previously noted and that it wouldn't leave once it hit. I had a lot of traffic from customers I never worked with before wanting to set up camps. the phones rang off the hook. We prepared at the office to make sure the equipment would stay dry and it could be rented. Even while that was happening everyone was saying..." it's probably not going to hit but we'll just take precautions".

The day it hit I was watching on tv while it came in and decimated my hometown of Corpus Christi and all the beach towns I went to all my life. towns destroyed in a day. I kept in contact with all my friends and family as much as I could but I knew they were having to deal with it in real time and me calling would only be a distraction. Thank God everyone I know is okay was all I could think.my parents, extended family, and friends were all without power too.Now the eye of the hurricane was heading north straight towards Houston.

Harvey is here. rain, calls, rain, calls, rain rain rain, call. The phones didn't stop ringing from the earliest of the morning to the latest at night. It just didn't stop. Family time was nonexistent but that's the price we had to pay. People needed help and I did what I could. It was hard not having enough equipment and hearing stories of what everyone was going through. I was getting more calls and called my competitors more than I did directly with customers. Having my family in the room for a week straight and I barely talked to them. Every call I took wasn't just one call and send the equipment, It was a call from the customer, a call to Roy, a call to the office, a call back to the customer if there was anything I missed. a call back to Roy to see if anything changed on delivery. Oh, I forgot to mention just about every major highway was under water. i10,59/69, 288, 45, most of the grand parkway and parts of 610 were under water.I couldn't physically make it into the office. I remember watching the news 24/7 to see what roads would potentially open during the storm. Every time there was a glimmer of hope, a damn would be released and a new area would flood. I had to cancel jobs in certain areas because we or anyone for that matter, couldn't make it to that area because they were Islands. Beaumont lost power and water.

After the storm had settled, the assessment of the damage was taken. It was the worst and most damaging in recorded history. Areas were under water. That Toys R Us I mentioned along with a Costco, Kohls, Heb, Target, Best Buy, etc....were all under water. This was 2 miles from my house. All of Kingwood, where my daughter's daycare was located was underwater. My subdivision was an island. I could remember a feeling of gratefulness and guilt at the same time because of how bad so many people had it. .I along with millions of others couldn't help because we had our own families and property to protect and frankly didn't have boats. I was in a position to profit at the same time which didn't help. I took comfort in knowing that I was a part of the solution and not the problem because there were a lot of people exploiting the problem. It was also just a matter of circumstance that we had what people needed similar to hotel, vehicle sales, furniture sales, raw material sales, etc

The shimmering beacon of hope and the silver lining in the destruction was the sense of community you felt from seeing stories of people helping people. Everything that makes people different took a back seat to the similarities we shared. We were from Houston, we were in trouble, we needed help. Race, ethnicity, religion, and gender didn't make a difference. People poured in from other states to help and lend a hand. Giving was in abundance. I don't know anyone in Houston that didn't give whether it be their personal time, money, or material belongings. It was great to see people come together. I remember seeing pro-NFL players loading people in boats. I never heard of the Cajun Navy till the hurricane. All this was a reminder that we would endure and persevere. Did I forget to mention people the calls, calls, calls, calls for people needing equipment after the storm? That didn't stop until October and the Astros won and everything was back to normal. THE END...That was a joke. It will take years and decades to rebuild but we will be better, faster, and stronger than ever before.
