Low-Profile Enclosure Heaters
Radiate heat inside narrow spaces to keep equipment warm and dry. These slim heaters fit where standard ones don’t. They protect equipment from premature failure caused by cold, condensation, and humidity.
Heaters with a thermostat automatically turn on and off to maintain the set temperature range. Heaters with a nonadjustable thermostat have a set range that you cannot adjust.
