Abstract
A refrigerated merchandiser (12) includes a display case (30) defining a product display region having an open-front isolated from the ambient air of the store by means of a downwardly directed inner air curtain (55) of relatively cold refrigerated air. The amount of airflow forming the air curtain is selectively increased in response to a signal from a controller (80) whenever a sensor (70) detects a disturbance in the integrity of the air curtain or from movement in front of the display case.
