Heaters Sizing and Selection Overview

When temperatures dip below the minimally acceptable ranges for electronics, our electric heaters can raise the temperature inside enclosures to appropriate levels. Heaters are designed to protect sensitive mechanical, electrical and electronic equipment from the harmful effects of condensation and corrosion. Two styles offer heating powers from 10 W to 800 W.

The graph in "Semiconductor Control Panel Heaters (for 10-60 W Heating Applications)" represents a painted-steel enclosure mounted in a calm-air building interior. The lowest temperature differential between room temperature and enclosure interior must be 10 F+ to prevent humidity and condensation. For outdoor applications, double the heating power requirement.
