Innovative Applications: 4 Unconventional Uses of Solid Desiccant Dehumidifiers

Updated: 4 days ago




Solid desiccant dehumidifiers are indispensable tools in controlling humidity levels in various industrial and commercial settings. Especially when those levels must reach dew points at or below 50°F. However, their versatility extends beyond traditional applications of long-term storage, cold storage, or ice rinks, with innovative uses continually emerging across diverse industries.


In this blog, you’ll learn about some applications of solid desiccant dehumidifiers that might not be as familiar to you. And we will highlight the efficacy and versatility of desiccant technology in solving unique challenges.

1. Preservation of Historic Artifacts:

Solid desiccant dehumidification plays a crucial role in the preservation of historical artifacts by controlling humidity levels to mitigate the damaging effects of moisture. Historical artifacts, ranging from ancient manuscripts to delicate artworks, are highly susceptible to deterioration caused by fluctuations in relative humidity. When exposed to excessive moisture, organic materials such as paper, parchment, and textiles can degrade rapidly, leading to irreversible damage.


One of the key reasons desiccant dehumidification is essential in artifact preservation is its ability to maintain stable humidity levels within archival storage environments. Ideally, these environments should have a relative humidity (RH) range of 35% to 55%, as recommended by conservation standards. At higher humidity levels, the risk of mold growth, insect infestation, and chemical degradation increases significantly. Conversely, excessively dry conditions can cause organic materials to become brittle and prone to cracking.


When the dew point temperature exceeds the temperature of the artifacts, condensation can form, leading to moisture absorption and subsequent degradation. For example, at a dew point temperature of 50°F (10°C), artifacts stored in an environment with a temperature below this threshold are at risk of moisture damage. Desiccant dehumidifiers help maintain dew point temperatures below critical thresholds, preventing condensation and preserving the integrity of historical artifacts.


Desiccant dehumidifiers also ensure archival storage facilities maintain optimal humidity conditions year-round, regardless of external weather fluctuations. For instance, during the hot and humid summer months, these dehumidifiers effectively remove excess moisture from the air, preventing mold growth and chemical deterioration.


2. Indoor Agriculture “Grow” Facilities.

Indoor agriculture facilities, commonly known as “grow” facilities, rely on precise humidity control to optimize cop growth and yield. Humidity levels significantly impact plant transpiration, nutrient uptake, and susceptibility to diseases such as powdery mildew.


For example, cannabis cultivation requires specific humidity levels throughout different growth stages. During the vegetative phase, maintaining relative humidity (RH) around 50% to 70% at a temperature of 70°F to 85°F promotes vigorous vegetative growth. However, during the flowering stage, humidity levels need to be lowered to around 40% to 50% to prevent mold and bud rot while ensuring proper flower development. Advanced climate control systems with humidity modulation capabilities are employed to create ideal growing conditions for various crops.

3. Hospital Operating Rooms.

In hospital operating rooms, controlling humidity is vital for maintaining a sterile environment, ensuring patient safety, and staff comfort. Excessive humidity can foster bacterial growth and compromise the effectiveness of sterilization processes. On the other hand, low humidity levels can contribute to discomfort and respiratory issues among both patients and healthcare providers and staff.


For instance, an ideal humidity range of 40% to 60% at a temperature of 68°F to 75°F is recommended for operating rooms. This ensures optimal conditions for infection control and patient comfort during surgical procedures. Modern HVAC systems with integrated humidification and dehumidification capabilities should be employed to regulate humidity levels dynamically based on real-time monitoring and feedback.


4. Disaster Recovery and Remediation:

Disaster recovery and remediation efforts can greatly benefit from the use of solid desiccant dehumidifiers because they effectively combat the damaging effects of excess moisture in the aftermath of natural disasters. Whether it's flooding, hurricanes, or severe storms, the ability to rapidly remove moisture from affected environments is crucial for mitigating further deterioration and facilitating the restoration process.


For example, in a water-damaged building with high humidity levels, the dew point temperature may exceed the temperature of the building materials. This creates an environment conducive to mold growth, corrosion, and structural degradation. By utilizing desiccant dehumidifiers, restoration professionals can lower the dew point temperature below that of the building materials, effectively extracting moisture from surfaces and accelerating the drying process.


Moreover, desiccant dehumidification offers precise control over humidity levels, allowing restoration experts to create optimal conditions for drying out water-damaged materials. This is particularly beneficial in scenarios where time is of the essence, such as preventing mold growth and microbial contamination in flooded buildings. By rapidly reducing moisture content in the air and surfaces, desiccant dehumidifiers help mitigate secondary damage and minimize the risk of long-term structural issues.


In addition to facilitating the drying process, desiccant dehumidification offers benefits such as the removal of odors associated with water damage, the prevention of warping and swelling of wood and other porous materials, and the restoration of indoor air quality by helping reduce airborne contaminants. Overall, the versatility and efficiency of desiccant dehumidifiers make them indispensable tools in restoring water-damaged properties and mitigating the impact of natural disasters on communities and infrastructure.
