What is the Role of the Desiccant Rotor Cassette?

The desiccant rotor is a kind of activated silica gel honeycomb rotor that originated in 1984, which is usually used in a desiccant dehumidifier. As the core of a desiccant dehumidifier, a complete desiccant rotor is usually able to play three roles: adsorption, desorption, and cooling. After more than 30 years of development, desiccant dehumidification technology has been widely used around the world. By continuously improving our technology, our company continues to develop high-quality desiccant rotors. Now, our company has become a leading supplier of desiccant dehumidifier cartridges and rotors worldwide.

The desiccant rotor is a patented dehumidifying wheel made of corrugated material. The shape of this dehumidifier wheel looks like a large cassette, so some people will also call it a desiccant rotor cassette.

Known as a market leader, desiccant rotor cassettes are widely recognized for their outstanding performance in most applications and environments. They consist of a very high silicone, low glass fiber, and acrylic surface coating. Unlike conventional dehumidification systems, desiccant dehumidifiers can dehumidify air at temperatures below 10°C or above 30°C. This is because the desiccant rotor material is usually silica, a porous form of granular silica with a network of internal microscopically interconnected pores that has a good water absorption effect. The water absorption of this grid is not affected by changes in the outside temperature.

The desiccant rotor is the "heart" of the desiccant rotor cassettes, and it determines the overall performance of the unit. The dehumidifier rotor is divided into process zone and activation zone by the housing structure and heat resistant seal. Moist air is drawn through the filter by the process fan into the honeycomb matrix of the rotor. As the air passes through the matrix of the rotor, the moisture is absorbed by the desiccant. The retained dry air is supplied to the room as "reactivated air". At the same time, the dried air passes through the honeycomb matrix of the filter and is then exhausted from the space using an exhaust fan. In addition, the desiccant wheel can be reused after the moisture in the desiccant is removed. This reduces overall operating costs and is economical for all industries.

The desiccant rotor cassette is used in a wide range of applications. This includes production lines and clean rooms in the pharmaceutical industry, rust prevention in aviation and defense equipment, humidity control in archives and museums, crop storage, and dry cooling in public buildings. The activated silica gel with controlled pore size is synthesized into a honeycomb matrix rotor with long service life. After 10 years of use, these desiccant dehumidifier rotors are capable of almost 90% of their original dehumidification capacity.

With expertise and decades of manufacturing experience, our company's rotor engineers optimize each system to provide the most reliable and highest quality desiccant dehumidifier rotors for the most demanding applications, achieving good performance and high efficiency throughout the rotor's life cycle. We are confident that you can find the best desiccant rotors on the market on our official website.
