Air cooled chillers having a condenser section (300) sized to match chiller capacity and auxiliary cooling requirements satisfied by use of an independent cooling coil (314) dedicated to providing auxiliary cooling. The independent cooling coil (314) is located within the current condenser (300), but utilizes available space within the existing condenser, as well as a small portion of the airflow driven by the existing condenser fan (320). Thus, the auxiliary cooling capacity is provided with a single dedicated coil design, but which otherwise uses existing equipment and space.
