When the inside temperature of a control cabinet changes, humidity or condensation can build inside. The additional moisture can cause equipment damage or performance failure. Using a fan assisted resistor heater such as the KH 503-251, warmer air can be dispersed on the inside, lowering the risk. It also helps to ensure a safe minimum temperature if needed. Enclosures that are in outdoor settings receive the most advantage from a heater, as they are exposed to the outside elements.
