Enclosure heaters protect electrical components from condensation moisture buildup that can result in corrosion and component failure. Heaters are available in various heating capacities, operating voltages, and mounting options.
Enclosure heaters prevent the formation of condensation and provide evenly distributed interior air temperature in enclosures.
Moisture can build up not only in outdoor or poorly insulated enclosures, but also in highly protected and well-sealed enclosures.
Moisture, especially when combined with aggressive gases and dust, causes atmospheric corrosion and can result in the failure of components such as circuit breakers, busbars, relays, integrated circuit boards and transformers.
Moisture and corrosion will remain low if relative air humidity stays below 60%. However, relative humidity above 65% will significantly increase moisture and corrosion problems. This can be prevented by keeping the environment inside a control panel enclosure at a temperature as little as 9°F (5°C) higher than that of the ambient air.

Stego small positive temperature coefficient (PTC) heaters are designed to prevent failure of electronic components caused by condensation, corrosion and low temperatures in small enclosures.
Compact convection heater for use in hazardous areas to prevent formation of condensation and frost in electrical enclosures and measuring equipment.
These touch-safe PTC heaters are for use in electrical panel enclosures. The design of the heater utilizes natural convection, which results in a circulating current of warm air. The heater's design minimizes surface temperatures on the accessible side surfaces of the housing.
The flat heater is used to provide evenly distributed temperature within enclosures with electric or electronic components. Its ultra-thin design makes it particularly suitable for high-density applications in which standard enclosure heaters are often too big.
The integrated thermostat is used to set the desired temperature while the high performance axial fan provides forced air circulation.
The heater design minimizes side surface temperatures of the housing. The small size of these control panel heaters makes them ideal for use in enclosures where space is at a premium.
The touch-safe plastic housing and the small size make these heaters ideal for use in enclosures with a high packing density. Each heater is equipped with a fixed set point thermostat and is easily wired via external pressure clamps.
These fan heaters are available with two different mounting systems – panel mounting or 35mm DIN rail mounting.
Highly efficient fan heaters prevent the formation of condensation and frost in the enclosure, and provide an evenly distributed interior air temperature in enclosures.
The plastic double insulated housing provides protection against contact with current-carrying components. This series is available with an optional fixed-point thermostat.
These compact high-performance PTC fan heaters are designed as stationary units for installation on the bottom of enclosures.
Hammond fan heaters use an incoloy tubular heating element to provide dependable temperature and condensation control within enclosures.
