If the interior temperature of an enclosure changes, humidity or condensation may collect inside. The added moisture causes such issues as equipment damage, data loss, or performance failure. With a fan assisted resistor heater such as the KH 503-501, warmer air can be dispersed easily, reducing the chances. It also helps keep the temperature at the minimum amount required. Control cabinets that are in outdoor settings receive the most benefit from a heater, as they are exposed to the outside elements.
