What Are Desiccant Dehumidifiers?

Unlike a compressor dehumidifier, a desiccant dehumidifier is a specialized device that doesn’t use coils, refrigeration systems, or compressors to reduce humidity out of the air. On the other hand, this dehumidifier will lower the moisture in your place using a process known as adsorption.

Desiccant-based dehumidification is mainly popular for low temperature dehumidifying since there’s no possibility of ice developing and intruding compressor operation.

Furthermore, desiccant dehumidifiers can get rid of a significant amount of humidity with more efficiency. As a matter of fact, this makes them a perfect option for heavy-duty moisture removal works in commercial, residential, and industrial spaces.

How Does A Desiccant Dehumidifier Works?

A desiccant dehumidifier works by utilizing a desiccant chemical to absorb damp from the air.  A fan will then draw the wet air towards the dehumidifier in which it is passed through the desiccant. After that, the desiccant moisture absorber is detained on a rotating wheel gradually.

The rotating wheel that is not utilized is then heated up, so the humidity will drip out to the water tank. Then, it will reheat the air and pump the desiccated air back into your space. This will surely reduce the relative moisture in the atmosphere.

Do Desiccant Dehumidifiers Work?

Usually, a desiccant dehumidifier cannot strive with the drying rate of a compressor. However, if you are wondering if this dehumidifier works, the answer is YES.

Desiccant dehumidifiers are efficient, and in fact, they can be the best choice for certain situations.

If you are concern about our environment, it is important to note that this device doesn’t contain the refrigerants that a compressor does, and such refrigerants can subsidize greenhouse gases.

Moreover, this dehumidifier works better at a superior range of temperatures, most especially in cooler settings. Actually, at a lower temperature, a desiccant dehumidifier is more efficient compared to compressors.

What Is the Best Desiccant?

Desiccant is a hygroscopic substance utilized to sustain or induce desiccation (a state of dryness) in its surrounding area.

Further, desiccants that are made for specialized purposes might be in forms excluding solid. Commonly, they are encountered in foods to preserve crispness. But for industrial purposes, they are utilized to control the level of water in the gas streams.

Even though some of these substances are chemically sluggish, others need specialized handling methods.

The best desiccant is silica – an otherwise sluggish water-insoluble and non-toxic white solid. But aside from this, there are also molecular sieves (usually zeolites), calcium chloride, calcium sulfate, and activated charcoal.

What Are The Different Types of Desiccant Dehumidifiers?

Here are the four different types of desiccant dehumidifiers.

  1. Commercial Desiccant Dehumidifier

Usually, this type is utilized by various kinds of construction workers. This is because a commercial desiccant dehumidifier is very effective in drying up the air and construction materials in extremely cold or warm weather conditions. In fact, most commercial construction institutions prefer this type over a compressor-based model.

  1. Disposable Desiccant Dehumidifier

Also known as a moisture absorber, this type of desiccant dehumidifier can only be used once. A disposable dehumidifier has a low humidity sucking capacity every day, making it ideal for small rooms that don’t need regular dehumidification.

One of the best things about a rechargeable desiccant dehumidifier is wireless and doesn’t need to be plugged in to use it.

However, this type is not ideal in a large room and space with very moist conditions. But it is best used in a small room that has minor moisture levels. 

  1. Full-size consumer-grade desiccant dehumidifier
