Dehumidifiers for Enclosures

Keep sensitive equipment dry inside enclosures. Also known as Peltier dehumidifiers, these dehumidifiers use electrical currents to remove moisture from the air. They’re smaller and require less maintenance than traditional dehumidifiers, since they don’t use refrigerant or compressors. However, they use more energy. Place dehumidifiers at the bottom of an enclosure, or mount them onto the included DIN rail. Moisture collects in the drain hose. Use a drain kit (sold separately) to direct moisture out of the enclosure.

Removal Capacity—Removal capacity is based on 80° F and 60% relative humidity.

Enclosure Humidistats


Fixed Actuation Point	Adjustable Actuation Point

Reduce the humidity in your enclosure to prevent condensation that can cause corrosion and short circuits. These humidistats switch your heater on when the enclosure reaches the relative humidity setting. Once the humidity falls by 5%, the heater switches off. To install, clip humidistats to a DIN rail.

CSA Certified, CSA-US Certified, CE Marked, and VDE Certified, these humidistats meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.

Fixed Actuation Point—Fixed humidistats work for most applications. They keep humidity below 65%, which is when condensation is most likely to form. Since they aren’t adjustable, the humidity setting can’t be tampered with or accidentally changed.

Adjustable Actuation Point—For critical components, use adjustable humidistats to set the relative humidity you need in your enclosure. Use a lower humidity setting in damp environments and places with frequent temperature changes. Condensation is more likely in these situations.
