A refrigerated air curtain redirection unit can be retro fitted to the front base of a an existing reach-in commercial open-display refrigerated cabinet, or provided as original built-in equipment for a newly manufactured cabinet to reduce refrigerated air spillage. The unit has a body part that protrudes outwardly of the open frontage of the cabinet at an upward angle and there is an inwardly curved part at its top region whereby an air vortex is formed that acts to draw air from the curtain at its base into an air duct of the cabinet.
