Warm the air in your enclosure to keep electrical components at the ideal operating temperature. These heaters also reduce humidity, preventing condensation that causes corrosion and short circuits. The fan blows hot air upward so it heats the enclosure evenly.

Heaters with thermostat are adjustable, so you can decide when the heater turns on and off. Heaters with humidistat switch on if the enclosure reaches 65% relative humidity or more, when condensation is most likely to form. Adapt heaters without built-in control to fit your system—add your own thermostat, humidistat, timer, or switch.

All heaters meet American, Canadian, and European safety standards. Heaters rated IP20 are designed so you can’t accidentally touch the circuits inside and get shocked. Heaters that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping.

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. These heaters create radiant heat, which spreads out in all directions without needing a fan. They also reduce humidity, preventing condensation that causes corrosion and short circuits.

Heaters run continuously—turn them on with a thermostat, humidistat, timer, or switch. Use a thermostat to control temperature or a humidistat to control moisture.

These heaters are rated IP32 to keep out objects the size of a screwdriver and drops of water falling from above. As UL and C-UL Recognized Components that are also CE Marked and VDE Certified, they meet American, Canadian, and European safety standards.

Mount these heaters in any position. To install heaters with mounting clips, screw the clips to your enclosure and press the heater into the clips.

These slim heaters fit into small spaces to protect electronics from cold and condensation. Made of aluminum, they radiate heat to warm the air in your enclosure. You can also use them in contact with components that need direct heat.

To control heaters, add a thermostat, humidistat, timer, or switch.

Heaters are rated IP30, which means objects larger than 2.5 mm, such as screwdrivers, can’t fit inside and accidentally contact live circuits. CE Marked and VDE certified, they meet European safety standards. They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping.

Screw these heaters into a light bulb socket in lockers, cabinets, and enclosures. They protect equipment from low temperatures and condensation.

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. For even heat, a fan blows upward to circulate warm air.

Choose a heater that clips to DIN rail or one that mounts to the bottom of your enclosure. Add a sensor (sold separately) that reaches the part of your enclosure you need to keep warm.

Heaters with thermostats turn on when the enclosure gets colder than the temperature you set. Heaters with humidistats switch on to reduce condensation when the relative humidity gets too high.

Heaters 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.
