To keep the condenser coil clean, the True TAC-36-LD open-air cooler has a reversing condenser fan motor that changes directions during the defrost off-cycles. The refrigeration system maintains a set temperature range between 35 and 40 degrees Fahrenheit, and the self-contained capillary tube system meters R404A refrigerant to keep temperatures cool. For structure and cold air retention, polyurethane insulation is foamed in the cabinet's walls. A plexiglass lower front panel is sturdy and break resistant, while the interior back wall is perforated for efficient airflow, ensuring contents are cooled.
