During humid seasons or environments, the excessive moisture in the air not only makes people feel uncomfortable but also causes furniture 

to mold, food to spoil, and even affects the lifespan of electronic devices. The rotary dehumidifier, as an efficient dehumidification device, is 

gradually becoming the "humidity buster" in households, industries, and other fields. This article will deeply analyze the working principle, 

advantages and disadvantages, applicable scenarios, and how to choose of the rotary dehumidifier, and will be supplemented with practical 

cases to help you fully understand this device. 

I. Working Principle of the Rotating Wheel Dehumidifier: Why is it so efficient?

The core of the rotating wheel dehumidifier lies in its wheel structure. The wheel is composed of special-shaped honeycomb channels made 

of a special material, with highly absorbent materials (such as silica gel or molecular sieves) covering the surface. During operation, the wheel 

rotates slowly, dividing into two areas:

Processing Air Area: When humid air passes through the wheel, the moisture is adsorbed by the absorbent materials, and the dry air is expelled.

Recovery Air Area: The other part of the wheel is heated (usually by electricity or steam), the adsorbed moisture is desorbed, and it is then expelled 

through the exhaust port.

This process repeats continuously, achieving continuous dehumidification.

Advantages: Compared with traditional compressor-type dehumidifiers, the rotating wheel type can work efficiently in low-temperature and 

low-humidity environments (even below 0℃), and there is no concern about the freezing of condensate water. 

II. Advantages and Disadvantages of Centrifugal Dehumidifiers: Do They Meet Your Needs?

Advantages:

• Highly adaptable to low temperatures: It can still effectively dehumidify in cold environments or low-temperature warehouses.

• No risk of condensation and ice formation: Unlike compressor dehumidifiers, it does not require frequent defrosting.

• Precise humidity control: It can precisely control humidity by adjusting the speed or heating temperature.

• High durability: Without a compressor structure, the failure rate is lower and the lifespan is longer. 

Disadvantages:

• High energy consumption: The regeneration process requires heating, and the power consumption is usually higher than that of the compression type.

• Limited working temperature: High-temperature environments (such as above 50℃) may affect the lifespan of the rotor.

• High initial cost: Due to the complex technology, the price is usually higher than that of traditional dehumidifiers. 

III. Application Scenarios: Where is it needed?

Rotary dehumidifiers are widely used in places that are sensitive to humidity or have special environments:

• In households and residences: basements, cloakrooms, bathrooms, etc. (areas prone to moisture).

• In industrial fields: pharmaceutical warehouses, food processing plants, electronic factories (such as lithium battery production requires

  an extremely low humidity environment).

• In commercial places: libraries, archives, swimming pools, gyms, etc.

• In special scenarios: cold storage, laboratories, moisture-proof storage, etc.

IV. How to Choose a Centrifugal Dehumidifier? Remember these points!

• Dehumidification capacity: Select based on the size of the space and the degree of humidity (for example, a 30㎡ room requires a

  daily dehumidification capacity of 10L or more).

• Environmental temperature: In low-temperature environments (such as cold storage), choose centrifugal models; in high-temperature

  and high-humidity environments, consider compressor models.

• Energy consumption ratio: Pay attention to the rated power and dehumidification efficiency, and choose energy-saving models.

• Noise level: For household use, recommend choosing models with a noise level below 45dB.

• Additional functions: Such as intelligent humidity control, mobile wheel design, air filtration, etc. 

V. Practical Case: Application of Centrifugal Dehumidifiers in Family Basements

The basement of a certain user's home measures approximately 20 square meters. It is cold and humid in winter (the temperature often drops below 10℃), 

and the problem of wall mold is severe. They previously used a compressor dehumidifier, but gave it up due to its low efficiency at low temperatures and 

frequent frosting. Later, they replaced it with a centrifugal dehumidifier with a daily dehumidification capacity of 12L, setting the target humidity at 50%.

Results:

After one week, the humidity in the basement dropped from 80% to 55%, and the musty smell disappeared.

The equipment operated continuously at low temperatures without frosting problems.

The monthly electricity bill increased by approximately 60 yuan (with an average daily operation of 8 hours), but it solved the long-term dampness damage. 

Conclusion

The rotary dehumidifier, with its low-temperature adaptability, stability and precise humidity control capabilities, has become an effective 

tool for dealing with humidity problems. Although it has relatively high energy consumption, it has obvious advantages in specific scenarios. 

When choosing one, it is necessary to consider environmental requirements, space size and energy efficiency factors to maximize its value. 

Say goodbye to humidity, start with a suitable dehumidifier!
