The Randell RF-COI107 Refrigerator Evaporator Coil 15-3/8\" X 4\" X 3-3/4\" provides reliable heat extraction to maintain consistent holding temperatures within your commercial refrigeration unit. This heavy-duty copper and aluminum heat exchanger works by circulating cold liquid refrigerant through its continuous tubing network; as a fan draws warm cabinet air across the dense metal fins, the refrigerant absorbs the ambient heat and evaporates, leaving behind chilled air to protect food safety. The compact dimensional footprint maximizes internal storage space while ensuring uniform airflow distribution. Utilizing this genuine OEM replacement component guarantees precise fitting and proper pressure ratings, which prevents refrigerant leaks, lowers energy consumption, and reduces operational strain on the system\'s compressor.
