A warehouse or storage spaces are large plain buildings used by individuals and businesses such as manufacturers, importers, exporters, wholesalers to store and preserve products before moving them out at a particular time. The storage time ranges from a few days to even a year.
Maintaining optimal humidity levels in warehouses and storage spaces is challenging as these places are not as insulated as residential spaces. Ventilation systems, cracked windows, door gaps, constant staff movement, and other openings lead to warm air entering these places and increasing humidity. Moisture levels in these places increase at night when surface materials such as floors, ceilings, crates packages – reach their dew point due to cooling off warm air, which leads to moisture accumulation due to condensation.
Humidity & Moisture Problems
High ambient humidity can lead to deterioration of the quality and shelf-life of the stored products. Some common symptoms of high humidity include sweating on concrete surfaces, rust, and rot, leading to inventory and capital equipment losses.
Products are often stacked one above the other or packed tightly in storage spaces and warehouses. Without appropriate humidity control, they can absorb moisture from the air and may have a wide-ranging impact. Deterioration of stored products’ chemical and physical properties, fungal growth, softening the structural matrix, discoloration, separation, etc. are major issues. Additionally, food and medicines stored in these places are at higher risk as mold and mildew growth can pose a significant health hazard to consumers.
Working in humid and muggy conditions can also be quite unpleasant for employees and may lead to frustration. To prevent such damage, storage space and warehouses should maintain optimum humidity around the clock to improve the humidity conditions, and one of the most efficient ways to do so is using a dehumidifier.
Using Dehumidifiers to Mitigate High Humidity Levels in Warehouses and Storage Spaces
The optimum humidity level for storage areas and warehouses ranges between 45%-55% RH. Dehumidifiers can significantly reduce moisture issues by providing additional airflow during daytime and mitigate condensation issues that occur overnight, controlling dew points and relative humidity in warehouses, indoor grow rooms, and archive storage facilities.
Heavy-duty dehumidifiers are made of durable materials and higher capacity and can handle more expansive space. When used in conjunction with HVAC systems, these machines can efficiently remove more moisture, allowing you to turn up your thermostat. Warehouse dehumidifiers can save a ton on power consumption, reducing the cost of electricity.
How Warehouse Dehumidifiers Work
Most dehumidifiers work by pulling air into the unit using a fan. When the hot, humid air passes over the refrigerated coils inside the unit. The dry air is then reheated and released back into the room via an outlet. The collected moisture within it condenses and drained into a collection reservoir until it is exhausted. Many heavy-duty dehumidifiers are equipped with an internal pump that allows water to be pumped vertically into a collection area.
Most heavy-duty dehumidifiers are equipped with automatic humidity control that allows you to pre-set the ideal conditions – drier, normal, humid, and monitor the indoor humidity. These units shut down automatically whenever the collection reservoir becomes full or after the spaces reach the desired humidity levels.
Factors to Consider While Buying a Dehumidifier For A Warehouse
Selecting the ideal warehouse dehumidifier is essential to maintain the optimum humidity level to have the products stored in the right conditions. Some factors that are needed to be considered are mentioned below:
Area size: It is a measure of space that needs to be covered by the dehumidifier. Commercial warehouses and storage spaces are huge areas; hence you need a dehumidifier that efficiently covers this space. If the space is too large for one dehumidifier, you can consider purchasing multiple dehumidifiers.
Facility Climate: Factors such as local climatic conditions also influence the performance requirement of the dehumidifier. The number of doors in the loading bay, frequency of door opening and closing, and the amount of time outside air enter the facility also impact the dehumidifier’s performance.
Type of Products: Consider the type of products or items are stored inside the warehouse and storage spaces, as some articles and inventory are more sensitive to moisture than others. Facilities where employees and machinery operate continually or with great frequency usually include supplementary climate control systems like heating, cooling, or air filtration. Units used in these environments will have to meet increased or decreased performance specifications and integrate with these other climate control elements.

Tips for Maintaining Humidity Levels in Warehouses and Storage Space
Maintaining Clean Work Environment: Keeping your warehouse or space clean is ideal for monitoring moisture, machinery, and inventory. Frequently inspect the structure and check for damage. Look for moisture or water damage, inspect piping and windows through which humidity can leak inside, and help you identify and treat mold and mildew growth.
Keep Track of Inventory: If there is inventory at the storage space or warehouse, it should be stored up and out of the way. Inspect the packaging, and consider placing the sensitive products where they are easily accessible and be inspected frequently for moisture damage. Keep track of how long the products have been stored and carry out occasional inspection to help alleviate any concerns before they arise.
