What level should the humidity in industrial spaces be maintained at in summer?

10/24/2025

High summer temperatures and high humidity present a challenge for most industrial environments. Whether in manufacturing plants, warehouses, electronic equipment storage areas, or production processes in the food and pharmaceutical industries, excessively high or low humidity can negatively impact equipment, materials, and products.

Effects of high humidity

When humidity in industrial spaces exceeds 60%, it creates a breeding ground for mold, mildew, bacteria, and dust mites. These microorganisms not only affect air quality but can also directly damage facilities and stored materials. For example, in warehouses, metal components and mechanical equipment can rust due to prolonged exposure to high humidity. During the production and storage of electronic products, humidity can cause circuit shorts or corrosion, reducing the lifespan of the equipment.

Furthermore, in the food and pharmaceutical industries, excessive humidity can lead to raw material spoilage, mold, and even product safety concerns.

Effects of low humidity

While excessive humidity can be problematic, low humidity can also present numerous challenges. Humidity levels below 30% can cause delicate materials like wood, paper, and certain chemicals to crack or warp. In electronics manufacturing, low humidity can also trigger static electricity, damaging equipment or causing production line failures. Furthermore, workers exposed to dry environments may experience health issues such as dry skin and respiratory discomfort, impacting productivity.

Ideal humidity levels in industrial spaces

For industrial spaces, the ideal humidity control range should generally be maintained between 40% and 60%.

40-50% RH: This is the ideal humidity range for industrial spaces. It provides just the right amount of moisture, preventing mold and corrosion while also minimizing static electricity and drying issues. This range is suitable for most manufacturing, storage, and office environments.

50-60% RH: While this humidity range is still acceptable, prolonged exposure to this range can begin to cause moisture to accumulate, especially in poorly ventilated environments, potentially leading to problems such as mold growth and metal corrosion.

Over 60% RH: In industrial environments, humidity levels exceeding 60% can quickly lead to equipment corrosion, material deterioration, mold growth, and other issues. Especially in the food and pharmaceutical industries, this humidity level can have a serious impact on product quality and safety.

How to choose a suitable industrial dehumidifier?

Condensing dehumidifiers: Suitable for environments with high humidity and more normal temperatures, they are widely used in most industrial spaces.

Adsorption dehumidifier: suitable for low temperature or very low humidity environment, often used in sensitive industries such as electronics and chemicals.

Hybrid dehumidifiers: Combining condensing and adsorption technologies, they are suitable for a variety of different industrial environments and can provide greater flexibility.
