Desiccant Wheel Market Analysis, Segments, Growth Rate (CAGR) of 4.89% and Value Chain 2023-2033

Market Overview

Published Via 11Press: A desiccant wheel, also known as a rotary dehumidifier or a honeycomb dehumidifier, is an energy-efficient device used for dehumidification. It is commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems to regulate the humidity levels in indoor spaces. The Desiccant Wheel Market consists of a large wheel-shaped structure with a honeycomb-like matrix made of a desiccant material. The desiccant material is a substance that absorbs moisture from the air. Commonly used desiccants include silica gel, molecular sieves, and activated alumina.

The Desiccant Wheel Market size is expected to reach USD 700.67 Mn by 2033, up from its current value of USD 414.42 Mn in 2022, growing at an annual compound growth rate (CAGR) of 4.89% from 2023-2033.

As the wheel rotates, a portion of it is exposed to the humid air stream. The desiccant material in this section absorbs the moisture from the air, resulting in a decrease in the air's humidity level. The dried air is then released into the indoor space. Another section of the wheel is simultaneously exposed to a stream of hot air, which regenerates the desiccant material by evaporating the absorbed moisture. The moisture-laden hot air is exhausted outside, and the regenerated desiccant material is again ready to absorb moisture from the incoming air stream. Desiccant wheels are highly efficient in removing moisture from the air, and they consume less energy than traditional cooling-based dehumidifiers. They are especially useful in environments where precise humidity control is required, such as in museums, data centers, and pharmaceutical production facilities.

Desiccant wheels offer precise humidity control, which is crucial in many applications such as pharmaceutical manufacturing, food processing and electronics production. Desiccant wheels use natural desiccant materials like silica gel or activated alumina that are non-toxic and recyclable, providing a more sustainable and eco-friendly alternative to traditional dehumidifiers.
  • Maintaining proper humidity levels in manufacturing processes can improve product quality while decreasing waste production – leading to increased productivity. High humidity levels can foster mold growth and other health hazards in indoor environments. Desiccant wheels help maintain a hygienic indoor climate by reducing humidity levels and preventing mold growth. They're suitable for many applications, including harsh or corrosive ones.


  • Desiccant wheels require regular maintenance to ensure optimal performance; the desiccant material must be replaced periodically and the wheel cleaned regularly to prevent contamination. Due to their large size, desiccant wheels require adequate space for installation; in some cases, retrofitting an existing HVAC system may not be feasible due to space restrictions.
  • Desiccant wheels may not be suitable for all climates. They become less effective in areas with high humidity or temperatures, which could reduce their dehumidification capacity. Furthermore, desiccant wheels produce noise during operation which could be an issue in certain applications. Despite being energy-saving devices, desiccant wheels still have higher operating costs than traditional cooling-based dehumidifiers – especially when energy costs are high.
