What Is a Dehumidifier and How Does It Work?

A dehumidifier is a device designed to remove excess moisture from the air, helping to maintain a comfortable and healthy indoor environment. In high-humidity regions like Dubai and the UAE, dehumidifiers are essential for preventing mold, corrosion, foul odors, and damage to sensitive equipment or materials. At JAQS, we provide high-performance dehumidifiers for both residential and industrial applications, tailored for the unique climate conditions in the UAE.

Why Dehumidification Is Important in the UAE

The UAE climate is known for its high heat and humidity, especially in coastal cities such as Dubai, Abu Dhabi, and Sharjah. This excessive moisture in the air can lead to condensation, microbial growth, and degradation of goods and building structures. Installing a dehumidifier ensures better air quality, enhanced comfort, and protection for valuable assets in both homes and commercial environments.

Types of Dehumidifiers

There are two main types of dehumidifiers used in the UAE:

  1. Refrigerant (Compressor-Based) Dehumidifiers
    These work by drawing in humid air, passing it over cold coils to condense the moisture, and then reheating the dry air before releasing it back into the room. They are energy-efficient and ideal for warm climates like the UAE.

  2. Desiccant Dehumidifiers
    These use a moisture-absorbing material (desiccant rotor) to remove humidity from the air. Desiccant units are especially effective in colder environments or when extremely low humidity is required.

How a Dehumidifier Works

The basic working principle of a dehumidifier involves these steps:

  • The unit draws humid air into the system through a fan.

  • The air passes over cooling coils (in refrigerant types), where moisture condenses into water droplets.

  • The water is collected in a built-in tank or drained away via a hose.

  • The dry, dehumidified air is reheated slightly and released back into the room.

In desiccant models, the air passes through a rotating wheel coated with desiccant material. The moisture is absorbed and then removed through a heated regeneration process.
