Heatcraft Mullion Reach-in Unit Coolers are ideal for under-counter refrigerators. The thin line design allows the unit to be mounted behind the mullion with sufficient clearance for tray slides. A down flow fan arrangement draws air in at the top and discharges at the bottom. The result is superior air circulation and uniform temperature throughout the cabinet. This method of air circulation ensures limited box temperature rise when the cabinet doors are open. And, the versatile design is adaptable for mounting on the back wall or ends of a cooler.
