A refrigerated merchandiser includes a case defining a product display area and having a base, a lower flue, a first air passageway, and a second air passageway. The first air passageway and second air passageway are in fluid communication with the lower flue and with the product display area. The refrigerated merchandiser also includes an evaporator positioned in the first air passageway and a fan assembly positioned in the base in fluid communication with the lower flue to generate an airflow. A fan plenum into which the fan assembly is disposed includes an airflow divider to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway. The proportion of air between the first portion and the second portion is a function of the position and geometry of the airflow divider.

1. A refrigerated merchandiser comprising: a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area;an evaporator positioned in the first air passageway;a fan assembly with a single fan positioned in the base in fluid communication with the lower flue to generate an airflow; anda fan plenum into which the fan assembly is disposed, the fan plenum including an airflow divider to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, wherein the proportion of air between the first portion and the second portion is a function of a position and geometry of the airflow divider,wherein the fan plenum includes a top wall, a side wall, and a plenum base, and wherein the airflow divider partitions the fan plenum into a first duct and a second duct, the first duct in communication with the first air passageway and the second duct in communication with the second air passageway,wherein the airflow divider includes a first wall member and a second wall member, wherein the first wall member and the second wall member operably separate the first duct from the second duct, andwherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°, wherein an increase in α decreases the proportion of air between the first portion and the second portion of the airflow. 2. The refrigerated merchandiser of claim 1, wherein the single fan is an axial flow fan. 3. The refrigerated merchandiser of claim 1, wherein the single fan is a centrifugal fan. 4. The refrigerated merchandiser of claim 3, wherein the airflow divider is positionally adjustable. 5. The refrigerated merchandiser of claim 1, wherein the plenum base is positioned parallel to the top wall. 6. The refrigerated merchandiser of claim 1, wherein the side wall includes a bottom edge, and wherein the plenum base is removably secured to the side wall and is adjustable relative to the bottom edge. 7. The refrigerated merchandiser of claim 1, wherein the angular separation α of the first wall member from the second wall member is about 90°. 8. A refrigerated merchandiser comprising: a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area;an evaporator positioned in the first air passageway;a fan assembly positioned in the base in fluid communication with the lower flue to generate an airflow; anda fan plenum including a top wall, a side wall, and a plenum base into which the fan assembly is disposed, the fan plenum further including an airflow divider having a first wall member and a second wall member that operably separate the fan plenum into a first duct in communication with the first air passage way and a second duct in communication with the second air passageway, wherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°,the air flow divider configured to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, wherein a change in a changes the proportion of air between the first portion and the second portion of the airflow. 9. A refrigerated merchandiser comprising: a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area;an evaporator positioned in the first air passageway;a fan assembly with a single fan positioned in the base in fluid communication with the lower flue to generate an airflow; anda fan plenum into which the fan assembly is disposed, the fan plenum including an airflow divider to direct a first portion of the airflow to a first duct in communication with the first air passageway and to direct a second portion of the airflow to a second duct in communication with the second air passageway, wherein the proportion of air between the first portion and the second portion is a function of a position and geometry of the airflow divider, and wherein the airflow divider includes a first wall member and a second wall member, wherein the first wall member and the second wall member operably separate the first duct from the second duct, and wherein the second duct is partially defined between the first wall member and the second wall member. 10. The refrigerated merchandiser of claim 9, wherein the airflow divider is positionally adjustable. 11. The refrigerated merchandiser of claim 9, wherein the fan plenum includes a top wall, a side wall, and a plenum base, and wherein the side wall includes a bottom edge, and further wherein the plenum base is removably secured to the side wall and is adjustable relative to the bottom edge. 12. The refrigerated merchandiser of claim 11, wherein the plenum base is positioned parallel to the top wall. 13. The refrigerated merchandiser of claim 9, wherein the fan plenum includes a top wall, a side wall, and a plenum base, and wherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°, whereby a quantity of air discharged to the first air passageway with respect to the second air passageway is proportional to α. 14. The refrigerated merchandiser of claim 13, wherein the angular separation α of the first wall member from the second wall member is about 90°. 15. The refrigerated merchandiser of claim 9, wherein the single fan is a centrifugal fan.
