Mastering Moisture Control: Unveiling the Power of Desiccant Dehumidifiers with Polygon

June 1, 2023

Kyle Mattingly, a Project Manager at Polygon in Orlando, Florida, provides a concise overview of desiccant dehumidifiers and their operation.

Desiccant dehumidifiers are introduced as one of the most efficient and effective methods for removing moisture from the air. The central component of these dehumidifiers is the desiccant wheel, also known as a rotor. The desiccant wheel acts like a sponge, absorbing moisture from the air.

Different desiccant materials are used in the construction of the wheel, including lithium chloride, molecular sieve, and silicon gel. The wheel continuously rotates during operation, facilitating the moisture absorption process.

The dehumidification process involves two separate air streams. The first is the process air stream, which is drawn into the dehumidifier through the process inlet. As the air passes through the dehumidifier, the moisture present in the air is absorbed by the desiccant wheel. The dehumidified air exits the dehumidifier through the process outlet, delivering drier air to the conditioned space.

The second air stream is the reactivation air stream, also known as the regeneration air. This air is introduced into the dehumidifier and heated, typically using electric heat elements, gas burners, or steam. The heated air then passes through the desiccant wheel, capturing the accumulated moisture from the wheel. The moisture-laden air is discharged or exhausted outside the dehumidifier.

The video emphasizes the importance of proper understanding and utilization of desiccant dehumidifiers for effective moisture control. It encourages viewers to reach out to the Polygon team for any questions or further information.

Polygon’s expertise in desiccant dehumidification technology is highlighted in the video’s overview, emphasizing their commitment to providing comprehensive solutions for moisture-related challenges. By explaining the principles of desiccant dehumidifiers, Polygon aims to educate and assist viewers in understanding the benefits and applications of this technology.
