Abstract: An anti-condensation control apparatus for a refrigeration device generally includes a sensor module and a control module. The control module receives an input from the sensor module and compares the input to a set point. The control module generates an output indicative of a difference between the input and the set point and updates the output based on the input from the sensor module. A heater modulator controls a heater based on the output from the control module to maintain a temperature of the outer surface of a refrigerated device such that relative humidity adjacent the sensor module is substantially between 90-95 percent relative humidity, or slightly above dew point.
