Heaters

Enclosure heaters protect electrical/electronic 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. Larger capacity heaters include a fan to circulate heat inside the enclosure. Some models include integral thermostats.

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.
