Types of Dehumidifiers
Humidifiers are generally classified according to their applications and working principle. Each category has its pros and cons. Basing on applications, dehumidifiers are regarded to be either portable or industrial. When it comes to working principles, these appliances are categorized as a desiccant type or refrigerant type. Read our indepth article on this subject here.
These appliances are mostly designed for homes and office premises. Their daily capacity ranges from 10 to 30 liters. Often, they are used to reduce humidity and for drying laundry. The aesthetic look of these humidifiers is their most prominent feature. They come with control panels, which have features such as timers and fan speed.
Just as the name suggests, these dehumidifiers are mostly used for heavy industrial operations. Their daily rating ranges from 30 to 1200 liters. They can either be portable (fitted with wheels) or permanently fitted on walls, floors, and ceilings. They are characterized by their bulky and strong nature. Their control panels have basic functions. The humidifiers come with a basic filter and a humidistat, which is used to preset the required humidity level.
Indoor Pool Dehumidifiers
These dehumidifiers are mostly installed indoors in spas, Jacuzzis, and rooms that have heated pools. They are also fitted on ceilings, walls, and floors. In most cases, wall-mounted indoor dehumidifiers have a limited capacity. Therefore, they are only used in rooms that have small swimming pools. Roof-mounted indoor dehumidifiers have a larger capacity. This makes them suitable for rooms that have larger pools.
Refrigerant Type Dehumidifiers
These appliances are also referred to as condenser drying, condensation type, or mechanical dehumidifiers. They use the refrigeration cycle to lower humidity levels. The humidifiers come with a condenser coil and an evaporator. The fan attracts humid air to the evaporator, where it is chilled below dew point to condense into water. The water is then collected in a tank. Refrigerant type dehumidifiers are recommended because they are cheap to buy and use. They are similarly energy efficient.
Desiccant Type Dehumidifiers
These units consist of a rotating desiccant wheel. Humid air is drawn to the wheel by a fan. The wheel absorbs all moisture and releases dry air back into the rooms. As a result, the wheel often gets wet. To dry it, hot air is passed through the system. Desiccant type dehumidifiers are preferred because they are also cost effective. Besides this, they can work perfectly in rooms that have low temperatures and humidity levels.
Factors to Consider When Buying a Commercial Dehumidifier
Before you purchase a dehumidifier, several factors ought to be considered. This will help you overcome the confusion that is associated with making this decision. These factors include size, a temperature range of the appliance, energy use and efficiency, noise level, water removal mechanism, and mobility.
The size of dehumidifiers depends on their working capacity. This implies the rate at which they absorb moisture from air within 24 hours. Larger dehumidifiers have a larger capacity than smaller units. This is why it is advisable to purchase units that have a large capacity if you need to dehumidify large rooms for a longer period.
Commercial dehumidifiers are typically rated according to their pint capacities. This correlates to the amount of space that the device will be used. Units with a large pint capacity are efficient as far as energy use and moisture removal are concerned. Low pint capacity dehumidifiers are suitable for cupboards, caravans, and bathrooms. Large pint capacity models are suitable for large basements and crawl spaces.
If the room that needs dehumidification experiences temperatures lower than 65 degrees Fahrenheit, you should consider buying a unit that is designed to operate at low temperatures. Garages, basements, and crawl spaces tend to get cold, more so in winter. Buying a model whose coil won’t freeze due to cold temperatures is, therefore, advisable. New models are Energy Star rated. This ensures efficiency even when temperatures drop to 42 degrees. Besides the climate range of a dehumidifier, you must also factor in the climatic conditions of your locality. This will help you buy the best industrial dehumidifier.
Standard commercial dehumidifiers have a power consumption of 50 to 80 watts. Manufacturers are coming up with Energy Star compliance models whose power consumption is marginal. Buying an energy efficient dehumidifier helps you save a lot of utility expenses. Models that have a higher rating have a low consumption and must, therefore, be given priority. Each model’s rating is determined by gauging the amount of water absorbed against the number of kilowatts used per hour.
Water Removal Mechanism
All dehumidifiers work by absorbing excess moisture from water. However, they have different water removal mechanisms. Typically, the devices have plastic buckets, which need to be frequently emptied. More often than less, the appliances shut off automatically when the buckets get filled. When you opt for such models, ensure that removing the bucket is not cumbersome.
You must similarly watch out for clicking locks and easy-grip handles. These features come in handy as far as handling filled buckets is concerned. Other models come with drain pipes, which allow water to drain into a sink. However, it is advisable to buy an appliance that comes with both the hose and reservoir. You should similarly ensure that the device bought has a hose that can be replaced when it starts leaking.
Noisy dehumidifiers can be quite a nuisance. Most models in the market have an average noise rating of 50 db. This can be quite irritating and disruptive, more so at night or during meetings. It is recommended to buy a commercial dehumidifier that comes with two-speed fans. This guarantees quiet and smooth operation even when humidity levels are low. Units that are less noisy are also energy efficient. Test an appliance’s noise level to establish its db. specification before you purchase it.
Mobility, Portability, and Convenience
If you opt for a heavy and bulky commercial dehumidifier, consider one that comes with caster wheels. Such machines can easily be moved from one room to another whenever a need arises. Find one that also has a long power cable because this will allow you to use it anywhere. For convenience purposes, look for models whose filters are washable. The filter must have the ability to shield the coils from dirt and dust. It should similarly be easy to remove and wash these filters effortlessly. To enhance the efficiency of the system, this should be done twice a month. This maintenance practice negates the need to replace the filters frequently.
