High humidity levels or excessive moisture in your building can lead to serious problems. According to research published by the World Health Organization (WHO), high humidity levels are associated with increased growth of mold, bacteria, and other microorganisms that cause human illness.

If you own or manage a distribution facility or warehouse where inventory is stored, humidity can also damage your products and the containers in which they are stored.

WHO states that one of the best ways to lower humidity and control indoor humidity levels is by increasing ventilation. With the right HVLS industrial fan, you can reduce bacteria growth, improve control of excess humidity levels, and improve air quality by increasing the ventilation in your space.

Humidity and Moisture Problems in an Industrial Warehouse

Industrial and warehouse spaces have a high risk of accumulating moisture. Accumulated moisture can damage not only the interior building structure, but also machinery and inventory. Not to mention, humidity can cause mold growth, posing a safety risk to working environments and employee performance.

How does moisture accumulate in your warehouse facility? Typically, air fluctuations are caused by open windows, doors, and anywhere warm air can enter the building. The temperature difference between the outside air and the inside air can cause condensation without proper air circulation.

When the temperatures cool at night, humidity is typically worse. When the warm air cools, surface materials such as floors and machinery begin to sweat. Humidity can cause rust, rot, and impose major risks on concrete floors.

Industrial ceiling fans can significantly reduce condensation problems associated with increased humidity and moisture, providing essential airflow through factories and warehouses during the day and at night, when moisture becomes a concern.

How to Reduce Humidity in a Warehouse with HVLS Fans and Ventilation

Even if you have an HVAC or air conditioning system and open windows or exhaust fan ports in your warehouse facility, it’s possible that air in your space isn’t mixing properly. The problem is probably inadequate air movement, resulting in the need to reduce humidity in your warehouse or industrial facility.

This is where a quality HVLS industrial ceiling fan can help: By creating a large column of airflow that affects a huge area, you can improve ventilation in your building. Larger HVLS fans can affect an area as big as 22,000 square feet.

This massive column of airflow leads to increased ventilation, which minimizes water vapor and moisture deposits by equalizing the room’s temperature, leading to a lower risk of bacteria and mold growth in your facility. With simple indoor air movement, you create a cooling effect.

Treating Sick Building Syndrome and Sweaty Slab Syndrome with HVLS Fans

Cutting down on bacteria and mold in your facility is not the only benefit of using HVLS fans to reduce moisture and humidity indoors. Sick building syndrome (SBS) is a condition that causes discomfort and sickness for workers in a particular area with an excessive humidity problem and lack of proper ventilation. The United States Occupational Safety & Health Administration (OSHA) says that some common symptoms of SBS include:

  • Headaches
  • Dizziness
  • Coughing
  • Difficulty concentrating
  • Eye, nose, and throat irritation
  • Fatigue

Although the specific cause of SBS is unknown, research has shown that buildings with stagnant air, poor ventilation, and higher humidity are much more likely to suffer from SBS.

Sweating slab syndrome (SSS) is another serious repercussion of high humidity levels. SSS occurs when humid air comes across a cold surface and attempts to lower its temperature to match the temperature of the surface. Since cold air holds less humidity than warm air, the air has to deposit its excess moisture on a surface, often a concrete floor or shelf. Moisture from SSS is a serious slip hazard that can also be dangerous for forklifts, carts, and other equipment that moves across the floor.

With an HVLS fan, you cut down on SSS by redistributing the air in your building and homogenizing its humidity. More air circulation in your space means a lower risk of SSS.

Final Thoughts on HVLS Fans and Humidity

Every building has a certain level of humidity and moisture, especially in parts of the world where humidity is naturally high. But if the humidity in your space becomes excessive, it can pose a danger to your employees, equipment, and inventory. Choose a dependable HVLS fan to improve airflow, decrease the amount of bacteria and mold in your space, and make your employees happier and healthier with better indoor air quality.
