The Beverage Air 203-126A Capillary Tube is designed to regulate refrigerant movement in compatible commercial refrigeration systems. This precision-sized tube features a 0.036" inner diameter, 0.087" outer diameter, and an 84" length, allowing it to meter refrigerant as it moves from the condenser to the evaporator. It works by restricting the flow of refrigerant, causing a pressure drop that allows the refrigerant to expand and absorb heat effectively within the evaporator coil. This controlled process helps maintain stable cabinet temperatures. Beverage Air 203-126A Capillary Tube supports efficient cooling operation, helps maintain food-safe storage conditions, and contributes to reliable refrigeration performance in commercial equipment.
