information How Customized Desiccant Dehumidifiers Benefit Brand Owners
Humidity control is critical in various industries, influencing processes, product quality, and the environment. In this article, as a trusted desiccant dehumidifier manufacturer, Norm Pacific explores the benefits of desiccant dehumidifiers, the differences between compressor and desiccant dehumidifiers, and the advantages of customized dehumidifiers in meeting specific needs.
What is a Desiccant Dehumidifier?
A desiccant dehumidifier is a type of dehumidifier designed to remove moisture from the air without the need for compressors or refrigerants.
It employs a slowly rotating desiccant rotor to absorb moist air, eliminating moisture through a heated air stream. The adsorption process involves the adherence of water molecules to the surface of the desiccant rotor. The unit then expels dry, dehumidified air back into the space, creating a more comfortable environment. This method allows effective dehumidification even in extreme temperatures and low humidity conditions.
Differences between Compressor and Desiccant Dehumidifiers
Compressor Dehumidifiers
Compressor dehumidifiers rely on the compression and expansion of refrigerant to remove moisture. The liquid-to-gaseous state change of the refrigerant under pressure and decompression is used to evaporate and cool in the pipeline. When the humid air comes into contact with the cold pipe, the moisture in the air condenses into water, thereby reducing the humidity in the air. That is, condensation is achieved by lowering the temperature of the system. Because the temperature needs to be reduced for condensation and dehumidification, it is unsuitable for colder environments like below 15°C, which will cause frost to form on the system. Compressor dehumidifiers are larger and make more noise than desiccant ones.
While effective in higher temperature and humidity environments like 25°C, and 70%RH, they face challenges in colder conditions, causing frost and inefficiency.
Desiccant Dehumidifiers
In the desiccant dehumidifier, the desiccant rotor rotates slowly to collect the passing humid air. Then, it removes it through the hot air flow, condensing and dripping water through the heat exchanger or directly discharging the moisture to the outside.
The advantage of desiccant dehumidifiers is that they still perform well in extreme temperatures (the dripping type is as low as above 0°C, and the exhaust type is about -15 degrees C) and low humidity (below 30% RH), which is beyond the capabilities of compressor dehumidifiers. They are quieter, more compact, and do not rely on refrigerants, making them flexible and environmentally friendly.
Benefits of Desiccant Dehumidifiers
Eco-Friendly Operation (GWP=0)
Desiccant dehumidifiers do not use compressors or refrigerants, eliminating the threat of contributing to global warming. The dehumidification function uses physical water absorption rather than chemical action so that no harmful chemicals will be produced during dehumidification.
Compact, Lightweight, and Quiet
These compressors-free dehumidifiers are smaller, lighter, and operate silently. They are easy to move and store, while their silent operation ensures minimal disturbance. These dehumidifiers offer a sleek and discreet solution for maintaining optimal humidity levels in homes or offices. Compared to a compressor dehumidifier with equivalent capacity, the weight of a desiccant dehumidifier is approximately 30% to 50% lighter than that of a compressor dehumidifier.
Frost-Free Operation
Unlike compressor-based systems, desiccant dehumidifiers can effectively function in lower temperatures without the issue of frost. This is because they work by removing moisture from the air using a desiccant material rather than cooling the air like compressor-based systems.
When the environment cools down, such as below 15°C, a compressor dehumidifier's evaporator (cooling coil section) may reach below 0°C and frost, necessitating a defrosting process, resulting in a significant reduction in dehumidification capacity. Generally, the dehumidification capacity of a compressor dehumidifier, at 27°C, is reduced to only about one-third at 15°C and further diminishes to about one-sixth at 5°C. In contrast, a desiccant dehumidifier employs physical moisture absorption, followed by reheating for regeneration. The moist and warm water vapor is cooled and condensed by room-temperature air in the heat exchanger. Even in a 5°C environment, it can maintain over 80% of its dehumidification capacity.
Incorporated Heating Function
Apart from dehumidification, they often include a heating function, aiding in deodorization and sterilization. Due to the adsorption and heating effects of the desiccant rotor, experiments have confirmed that the desiccant dehumidifier, running for 1 hour in a 7.7m3 indoor space, achieved a removal rate of 95.2% for bacteria in the air compared to the control group.
Delivery of Dry and Warm Air
Blows dry, warm air, which is the most powerful against cold and dampness. Therefore, they are ideal for speedy laundry drying and preventing dampness, musty odors, and indoor condensation, creating a healthy environment in any room. In some regions, users take advantage of the dry and warm air expelled by the desiccant dehumidifier during operation to expedite the drying and deodorizing of damp clothing, making it an efficient clothes-drying machine.
Deodorizing & Preventing Mold
Warm air can be used to dry and prevent mold and unpleasant odors. Thermal catalyst coating can decompose odors and harmful gases. For instance, Norm Pacific’s desiccant rotor, following JEM1467 standards, was tested for formaldehyde removal, demonstrating an approximate removal rate of 98%.
