Additional Product Information
When the inside temperature of a control cabinet changes, this causes humidity or condensation to collect inside. The additional moisture can lead to equipment damage or a performance failure. Using a PTC heater such as the KH 501-025, warmer air can be dispersed on the inside, reducing the risk. It also helps to maintain a minimum temperature if needed. Cabinets that are in outdoor settings receive the most advantage from a heater, since they are exposed to the outside elements.
