An evaporator assembly for refrigerating a cold table comprises a housing, an evaporator coil, and at least one electric fan. The housing comprises a mounting portion that is configured and adapted to support the housing from a vertical wall of the cold table. The evaporator is inclined within the housing to reduce the occurrence of evaporator freeze-up. The evaporator assembly is configured to discharge air from the housing both upward and horizontally. Air is drawn into the housing from a space between the housing and the vertical wall of the cold table.
