Warm the air in your enclosure to keep electrical components at the ideal operating temperature. Heaters also reduce humidity, preventing condensation that causes corrosion or short circuits.

Under 2 ½” long, these tiny heaters fit in tight spaces, such as security camera enclosures. For localized heat in a large enclosure, place them near batteries and other parts that don’t work well in the cold.

A sensor attached to the heater might signal that it’s warm enough near the heater, while other parts of the enclosure are still cold. Moving the sensor away from the heater helps you keep electronics warm and dry, anywhere in the enclosure.

Heat the airflow from equipment-cooling fans to warm equipment and reduce humidity.
