Moisture build-up in industrial control enclosures needs to be controlled and eliminated because it can lead to mold growth. Mold is usually visible and has an unpleasant, musty smell. Some types can be toxic to humans, and mold growth won't stop on its own once it starts. You can prevent mold from growing in your workspace by eliminating moisture. Controlling moisture in the air and on surfaces is important to keep your workplace and your employees safe from harmful mold growth.

Check your enclosure for any leaks. Scan all pipes, faucets and other water sources for signs of water. Check floors, walls and ceiling for signs of water damage, such as water spots or puddles. If there are any leaks, call a plumber or your company's maintenance technician, if you have one, to fix the leaks. This will prevent the leaks from becoming bigger problems in the future and will prevent unnecessary moisture build-up.

Keep air passing through the space while you are working in it. Open all doors and windows and keep them open throughout the work day. This allows fresh air to circulate and moisture to evaporate more quickly than if you had kept the doors and windows closed.

Use fans around the clock. Household fans can help, but an industrial fan will work much more quickly. Industrial fans operate at high speeds to help moisture evaporate rapidly. Industrial fans are often used in buildings that have flooded. You can leave the fans on when the workspace is closed and overnight. You can purchase industrial fans at hardware supply stores.

Use a dehumidifier in industrial spaces on humid days. A dehumidifier works in the opposite way as a humidifier--while a humidifier pumps moisture into a room's air, a dehumidifier sucks moisture from the air. If you work in a climate that is prone to rain or humidity, a dehumidifier can help control the associated moisture in your industrial control enclosure. You can purchase dehumidifiers at hardware supply stores and household supply stores.
