What is mean by anti condensation heater?

An anti-condensation heater is a device designed to prevent the formation of condensation on surfaces, particularly in environments where temperature differences can cause moisture buildup. These heaters maintain a surface temperature above the dew point, thereby inhibiting the condensation process. They are commonly used in areas like electrical cabinets, glass display cases, and refrigerated units to protect sensitive equipment and maintain visibility. By reducing condensation, these heaters help prevent corrosion, mold growth, and damage to stored items.
