An energy saving apparatus for use with a heat exchange system having a cooled chamber, a compressor, a condenser, an evaporator, an evaporator fan, and refrigerant within refrigerant carrying lines has an evaporator fan controller for monitoring operational status of the system (cooling or non-cooling) and setting an energy saving operational speed for the evaporator fan based on the operational status of the system (cooling or non-cooling) and a current sensor coupled to the evaporator fan controller for detecting the operational status of the system (cooling or non-cooling). If the system is detected as cooling, the evaporator fan controller directs the evaporator fan to operate at a high speed and if the system is detected as not cooling (non-cooling), the evaporator fan controller decreases the operational speed of the evaporator fan to a low speed, thereby decreasing evaporator fan produced heat, resulting in an overall decreased energy requirement for the heat exchange system.
