Dubai’s summer heat needs some relief; swamp evaporative coolers and misting fans are just the solutions. Selecting the one requires a consideration of their features and applications:
Reduces and maintains the level of humidity in the air, usually for health or comfort reasons, or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It can be used for household, commercial, or industrial applications. Large dehumidifiers are used in commercial buildings such as indoor ice rinks and swimming pools, as well as manufacturing plants or storage warehouses.
Dehumidifiers extract water from air that passes through the unit. There are two types of dehumidifiers - condensate dehumidifiers and desiccant dehumidifiers.
Condensate dehumidifiers use a refrigerator to collect water known as condensate, which is normally greywater but may at times be reused for industrial purposes. Some manufacturers offer reverse osmosis filters to turn the condensate into potable water. Some designs, such as the ionic membrane dehumidifier, dispose of water as a vapor rather than liquid.
Desiccant dehumidifiers (known also as absorption dehumidifiers) bond moisture with hydrophilic materials such as silica gel. Cheap domestic units contain single-use hydrophilic substance cartridges, gel, and powder. Larger commercial units contain hot air recovery systems in order to remove humid air from outside the room.
Dubai does not experience high humidity the whole year. However, its summers are very hot and humid. September is by far the most humid month with humidity levels reaching as high as 90%.Problems because of Humidity There are two main reasons to explain the atrociously high levels of humidity in Dubai. The first one is that the country is located within Northern desert belt which is mainly characterised by arid subtropical climate. The second one is the presence of the sea. If the wind blows from the coast, it usually gets very humid. Also, there can be heavy fog. These factors contribute to the unusually high levels of humidity in Dubai.
As you can see, the humidity situation in Dubai tends to be generally high given that the city is located on the coast. High humidity has several disadvantages. These include the following:
Prevents formation of bacteria, mites, mould and mildew High humidity, especially in the summer months, provides favourable conditions that encourage mould formation and thriving of mites at a very rapid rate. Since mould, mites and mildew require a constant supply of moisture to survive, you can expect to suffer from this problem. A dehumidifier is important as it reduces the moisture in the air and hence helps you control mould and dust mite formation.
High humidity is associated with a raft of health issues because it is the main cause of bacteria formation. High humidity can lead to sleeping disorders, respiration problems, burning of eyes, throat and nose, asthma and allergies brought about by mould spores. The perfect solution for this problem is investing in a dehumidifier that has an efficient filter.
If the air contains too much water, it will condense on cooler surfaces like walls and window glasses. If this water is left to stay on your walls and windows, it poses a real danger of damage to your property. It can also damage your painting, important file records or valuable books and other properties.
If you have expensive electronic equipment like Flat Screen TV, home theatre or cameras, they are at the risk of being damaged by high humidity. High humidity in homes leads to water condensing on PCBs of electronic gadgets or even rusting of PCB. By installing a dehumidifier, you could stop your electronic gadgets from being terribly destroyed.
It is not uncommon to visit a posh house and then be met with bad smell. The bad smell is brought about by high humidity. High humidity can also damage expensive clothing items and your carpet.
So what would you prefer? Purchasing a dehumidifier or putting your household property and building at risk? The simple solution to all the above problems is to invest in a dehumidifier. As you can see, there are many reasons to invest in a dehumidifier. How to reduce humidity in home in Dubai As beautiful as Dubai is, the humidity and heat can be a nightmare. At such times the only solution might be to go indoors to your cooled room. But what if you have to deal with humidity problem outdoors and indoors? To put it simply, that’s just plain torture. In this section, we tell you top three things to do to reduce humidity in your Dubai home.
If air is properly circulated in the room, it can dramatically reduce humidity in your home. A room without proper circulation feels stuffy and there is a feeling as if air is stagnant. This usually leads air to become denser and a rise in humidity.
To improve circulation, use ceiling fans and where necessary, extra floor fans and box fans. Properly circulated air in the room dries out and reduces the humidity which leads to the not only cooler but also more comfortable room. Ensure ceiling fans are rotating properly for the season. During summer, the proper way for fans to rotate is counterclockwise. During winter, you should reverse rotating direction so that cooler air is pulled up, while warmer air is rotated around the room.
Ventilation fans in your bathroom and kitchen are usually used to reduce bad smells in these rooms. The rooms tend to produce a lot of moisture and lack of ventilation quickly leads to mould growth.
Use the vents in these rooms to reduce excessive humidity and the rooms will be safer and even more comfortable. Ensure that these vents are not stopped or blocked in any way. Always ensure that the vents are kept clean and don’t have any debris and dust.
Preventive maintenance can go a long way in ensuring proper levels of humidity in your home. Always make sure that you schedule regular maintenance on the major units in your homes like hot water system and HVAC systems as this will ensure long life and efficiency.
Also, you can perform the following preventive measures to reduce humidity in your Dubai home: Watch out for any leaks in your ceiling. Check seals and replace weather stripping and caulk around windows and doors which can let in hot and humid air Inspect your air ducts for moisture and ensure that they are properly insulated Reduce the overall moisture in your home A dehumidifier is the surest and the most efficient way to check the humidity in the rooms of your home. If only certain places in your home experience high humidity, a basic dehumidifier might help. However, if you have humidity in the whole of your house, you may want to buy a whole-house unit. A dehumidifier is not part of your AC system and can be run independently of your AC unit. It can also operate on days with high humidity but temperatures are reasonable. A dehumidifier combined with your air conditioning unit will dramatically improve the moisture-removing capability of the units.
Using less water for shower is another way to decrease moisture in your home. When bathing, ensure you take shorter and cooler showers as this will reduce the amount of steam in the bathroom. Removing houseplants also a good way of reducing humidity in the house. This is because plants usually release moisture in the air and if you have lots of houseplants, they could be the reason for the high humidity in the house. You can either put these plants outside during the humid months or have them concentrated in one room. Applications of dehumidifiers
A dehumidifier is used for various residential, commercial and industrial purposes. While a rise in temperature is noticed immediately, a rise in humidity gets unnoticed and will cause adverse effects in the long term. Some of the wide areas where high-quality dehumidifiers find their applications include the following.
Humidity in the air results in a damp environment which is a breeding ground for fungus and insects such as moths, and fleas which require damp environments to breed. It certain cases, the humidity in the air leads to respiratory and perspiration issues in the human body. Dehumidification of air keeps the health issues away and the environment free from pests.
A humid climate is extremely uncomfortable as it causes excessive sweat and perspiration of fluids from the human body leading to dehydration and nausea. The precipitation levels of the body vary due to moisture leading to fatigue quickly.
While human lifestyle becomes uncomfortable due to the humidity in the air, it also causes issues in material objects such as pipes and grills to rust. These get rusted more quickly due to the moisture in the air. This results in frequent maintenance of iron ducts and pipes. A high-quality dehumidifier helps in comforting the human lifestyle. Also, it reduces the cost of repair and maintenance of households by removing the humidity in the air. wall mounted dehumidifier Cool Group International
High-quality Dehumidifiers are widely used in industrial environments to maintain a certain level of humidity to create a conducive environment to produce or manufacture humidity-sensitive products. eg. ferrous materials are prone to rusting due to humidity and hence steel storage areas should have controlled humidity. Dehumidification of air is essential in such environments.

We will explain based on the technology and also based on the applications. Types of High-quality Dehumidifiers based on technology Based on the technology, there are two types as listed here:
These are the most commonly used dehumidifiers that usually work like a refrigerator by drawing moist air. Thereafter evaporating the moisture in the air over a condensing coil, thus removing the water. The dry air is released back into the environment. High Capacity Dehumidifier Cool Group International These types of dehumidifiers suit normal room temperature environments (above 10°C). The condenser coil is at an optimal temperature above 10°C. However in colder climates, this becomes less effective. The water is collected in a tray in the machine or can be drained out through a drainage pipe.
These dehumidifiers suck the air and pass them over a material that absorbs the moisture in the air. The desiccant material is usually silica gel. This is the most natural disinfectant that we commonly find in shipped electronic goods. They don’t condense the air over the coil and hence, they are ideal for colder climates. The wet air is taken through the inlet and the moisture content is absorbed by the desiccant. The outlet air will be dry which is recirculated in the room. Types of Dehumidifiers based on applications There are numerous applications for dehumidifiers and we are explaining only a few of them:
These are usually industrial high-quality dehumidifiers which are heavy duty. These can withstand lower climatic conditions. Desiccant types are used under these conditions and come in huge variety of dehumidification capacity ranging from 0.35 kg/h to 58 kg/h. These are for dehumidification of air during storage of medicines, vaccines, fruit and vegetables such as banana, onion, potato etc. Read More about Cold Room Dehumidifier dehumidification Principle Cool Group International
Warehouses need to have controlled humidity. This is especially true when you are storing items such as medicines, fruits, vegetables, tobacco etc. Depending on the size of the warehouse, the capacity has to be decided. Normally condensation types are used for temperature above 10°C. We have models with dehumidification capacity ranging from 22 liters/day to 520 liters/day Read More about Warehouse Dehumidifier
As you can imagine swimming pools huge amount of humidity. This will cause extensive damage to the surrounding areas if left uncontrolled. The temperature of the water is different from the temperature of the surrounding. This temperature difference also causes excessive moisture. For this reason, all indoor swimming pools need to have a strong capacity for dehumidification of air, which is capable of working continuously. Read More about Swimming Pool Dehumidifiers
These are smaller in size as its name says. They are lightweight and can be carried easily and are relatively cheap. They are very effective for smaller spaces and they are mostly condensation types. They typically use a coolant to cool the surface by condensing the air into water vapour. They work on the principle of condensation and they operate with very little noise.
