Expert Guide to Choosing and Pricing Pool Dehumidifiers

A pool dehumidifier is a specialized device designed to control humidity levels in indoor pool halls. By collecting moisture from the air, it helps prevent mold growth, equipment corrosion, and deterioration of air quality. These systems not only extend the lifespan of equipment and building materials but also create a comfortable and healthy environment for swimmers.

Their operating mechanism is typically based on refrigeration (compressor-based) systems or desiccant dehumidifiers, which draw in humid air, separate moisture from it, and return dry air to maintain balanced humidity levels. When selecting and purchasing a unit, factors such as dehumidification capacity, pool hall area, application type (residential or industrial), energy consumption, and additional features like timers, air filters, or digital displays play a crucial role.

To check the price of pool dehumidifiers and choose a model that suits your specific needs, it is recommended to consult reputable and specialized suppliers for a smart and efficient purchase.
Overall, selecting the right dehumidifier leads to reduced maintenance costs, improved energy efficiency, and enhanced comfort and health levels for both the pool environment and its equipment.

What Is a Pool Dehumidifier?

A pool dehumidifier is a device designed to control air humidity in indoor swimming pool areas and plays a crucial role in maintaining environmental and structural integrity. Due to continuous water evaporation from the pool surface, humidity levels rise, and if left uncontrolled, this can lead to vapor formation, equipment corrosion, structural damage, and reduced indoor air quality.

Pool dehumidifiers typically operate using refrigeration systems or moisture-absorbing materials. In this process, humid air is drawn in, excess moisture is removed, and the air is then returned to the pool area at a standard relative humidity level (approximately 50% to 60%).

The price of a pool dehumidifier depends on factors such as dehumidification capacity, operating type (refrigeration-based or desiccant), dimensions, power consumption, and additional features. Characteristics such as corrosion-resistant housing, fully automatic operation, low noise levels, and heat recovery capability help increase efficiency and reduce energy costs.

Overall, using a pool dehumidifier improves air quality, prevents damage caused by excessive humidity, and helps extend the lifespan of the pool structure, equipment, and facilities.

What Is Humidity?

Excessive humidity in enclosed environments not only causes discomfort and a heavy feeling but also creates ideal conditions for the growth of dust mites, fungi, and bacteria. Dust mites are microscopic organisms that multiply rapidly in humid conditions and are commonly found in bedding, carpets, curtains, and indoor air. These organisms can be highly irritating for individuals with allergies or asthma. Using a residential or pool dehumidifier helps control humidity levels and prevents the growth of these pests, significantly improving indoor air quality.

In indoor swimming pools, the absence of an effective dehumidification system can lead to serious problems. High humidity creates an ideal environment for mold, fungi, and bacteria growth, posing health risks to users and damaging pool equipment. Mold spores spread through the air and enter the body via inhalation, potentially causing respiratory issues, allergies, asthma, and even fungal infections.

Moreover, excessive humidity promotes the growth of various bacteria and microorganisms that can cause skin conditions such as itching, rashes, and superficial infections. Humid air also creates a suffocating and heavy atmosphere, which is particularly uncomfortable for individuals with asthma or respiratory conditions.

From a technical perspective, high humidity is a major enemy of pool equipment. It leads to metal corrosion, wood decay, and deterioration of paints and surface coatings. Over time, this results in damage to pumps, ladders, and other metal components. Additionally, water vapor condensation on walls, ceilings, and windows can cause stains, mold growth, and scaling, negatively affecting the appearance of the space.

Ultimately, excessive airborne moisture reduces visibility within the pool area, especially on swimmers’ goggles, and increases feelings of discomfort and suffocation. Therefore, using a standard pool dehumidifier is essential not only for protecting human health but also for extending equipment lifespan and preserving the aesthetic quality of the pool environment.

Methods of Reducing Air Humidity

To control and reduce air humidity in enclosed spaces, various methods are available, each selected based on environmental conditions and humidity levels.

• Use of Desiccant Materials: In small and confined spaces, moisture-absorbing salts or chemical desiccants such as silica gel can be used. This method is mainly suitable for closets, small storage areas, or poorly ventilated spaces, but it is by no means sufficient for large halls or swimming pools.
• Dehumidification Using Cold Surfaces (Mechanical and Thermodynamic Systems): This is the most common and effective method in industrial environments and large halls. In these systems, humid air is cooled as it passes over a cold surface (evaporator), causing moisture to condense. The dry and conditioned air is then returned to the space. This is the operating principle of refrigeration-based dehumidifiers, which are widely used in pools and industrial facilities.
• Electrical Dehumidification (Air Ionization): In this method, electric fields and ionic charges are used to attract and collect water particles suspended in the air. This technology is mainly applied in small or residential devices or specific applications and has not yet become as widespread as mechanical systems.

Overall, selecting the appropriate humidity control method depends on space size, relative humidity level, application type, and maintenance costs. In large environments such as indoor swimming pool halls, purchasing a dedicated pool dehumidifier is considered the most reliable and effective solution.

When Do You Need to Use a Pool Dehumidifier?

A dehumidifier is a necessary tool for indoor swimming pools where it is not possible to ventilate or remove the excess moisture in the air and replace it with fresh.
Or when the outside air is humid and has a high relative humidity (above 50%RH), and replacing it does not reduce the humidity around the pool (such as in the north or south of Iran). In this situation, it will be necessary to use a pool dehumidifier to reduce the humidity of the indoor pool area.
In general, if the relative humidity in indoor pools at 25 degrees Celsius is less than 40% RH, the swimmer will feel cold (the ambient air temperature of indoor pools should be around 25 to 29 degrees Celsius based on the type of use).
Also, the presence of more than 60% humidity in the air around the swimming pools is not suitable in any way because the humidity above 60% not only deprives the swimmers of comfort when breathing but also causes a lot of damage to the building and equipment such as electrical and mechanical engine room machines in the long run.
Whenever the temperature difference between the water of the swimming pool or hot tub and the surrounding air is more than 2 to 3 degrees Celsius, the process of water evaporation and increasing humidity starts (especially when there is a hot tub).
Based on the environment type, dehumidifiers are divided into two types: those without a heating coil and those with a heating coil for heating the air coming out of the device.

How Pool Dehumidifiers Work

Pool dehumidifiers remove moisture from the air by suctioning the indoor air and replacing it with dry air at a higher temperature (in modes that have a heating coil) or with the same ambient temperature (in models without a heating coil).
Most dehumidifiers work with electricity and have a compressor, condenser, and evaporator parts. These devices are made as an all-in-one package.
They are selected and adjusted according to the percentage of relative humidity, the temperature of the environment, and the area of the pool. This makes them able to extract moisture from the environment and convert it into distilled water, which then drains through the drainpipe.

Mechanical/Refrigerated Pool Dehumidifiers

One of the applications of mechanical dehumidification systems is for indoor swimming pools. The main advantage of these systems is that the latent heat, sensible heat, and the heat produced by the operation of the system's compressor can be used separately in any part of the building that needs heating.
One of the most common methods of dehumidification in dehumidifier devices is to use the same thermodynamic cycle method of air conditioning systems or the use of a cooling coil.
In this method, the humid air is directed over the cold coil of air-conducting devices or direct expansion coils, the moisture contained in it is distilled, and dehumidification occurs.

Components of a Pool Dehumidifier

A standard pool dehumidifier consists of the following components:

• Fan: Draws in and circulates air through the unit.
• Evaporator Coil: A cold coil that condenses moisture into liquid.
• Condenser Coil: A hot coil that releases absorbed heat.
• Compressor: The heart of the refrigeration system, compressing refrigerant and enabling the cooling cycle.
• Refrigerant: A substance such as R410a or R134a that absorbs and releases heat.
• Drain Pan/Pump: Collects and discharges condensed water.
• Air Filter: Removes airborne particles and protects internal components.
• Control System: Includes humidity sensors (humidistat) and temperature sensors to regulate operation.
• Corrosion-Resistant Housing: Typically made from galvanized steel or anti-corrosion coatings due to high humidity and chlorine exposure.

Types of Industrial and Pool Dehumidifiers

Pool dehumidifiers are classified based on operating mechanisms, installation methods, and specific applications. Below is a detailed explanation of each type, including operating principles, key components, advantages, disadvantages, common applications, and practical examples.

1. Refrigeration Dehumidifiers

These are the most common dehumidifiers used in indoor swimming pools and operate based on the refrigeration cycle, similar to air conditioners and refrigerators.

Air is drawn into the unit by a fan and passes over the evaporator coil, where its temperature drops below the dew point, causing moisture to condense.

Condensed water is collected in a drain pan and discharged via piping or a pump.

The dried air then passes over the condenser coil, is reheated, and returned to the environment.

The compressor compresses refrigerant such as R410A or R32 to sustain the cycle. Some models include heat recovery systems to reuse waste heat.

Capacity: Typically 20–500 liters per day, depending on pool size.

Advantages:

High efficiency in controlling both temperature and humidity.

Energy recovery of up to 100% of compressor waste heat, saving 30–50% energy.

Easy installation and operation with relatively low initial investment.

Suitable for medium to large pools with stable performance.

Produces useful heat during colder seasons.

2. Desiccant Dehumidifiers

These systems use moisture-absorbing materials such as silica gel or zeolite without cooling.

Air passes through a desiccant wheel or bed where moisture is absorbed.

During regeneration, heated air (80–120°C) releases the absorbed moisture.

No liquid water is produced; moisture exits as vapor.

Capacity: 10–200 liters per day, more efficient at lower volumes.

Advantages:

• Excellent performance at low temperatures.
• No need for water drainage.
• Quiet operation and year-round efficiency.
• Reduced risk of mold and bacterial growth.
• Useful heat output during regeneration.
