Description
The FBD Expansion Accumulator Tank is a critical pressure-management component for frozen beverage dispensers (slush and frozen cocktail machines). With a 21.5 oz capacity, this tank acts as a buffer to absorb pressure fluctuations in the syrup and carbonated water lines, ensuring a consistent mix and protecting internal valves from “hammering” or sudden surges. Constructed from high-strength, food-safe materials, it is a genuine OEM part designed for long-term reliability in high-volume fountain environments.
Technician’s Repair Tip: If your machine is producing inconsistent drink texture or “shuddering” during the dispense cycle, the accumulator tank may be waterlogged or the internal diaphragm may have failed. Check the air-charge (if applicable) and ensure all fittings are secured with the correct O-rings to prevent CO2 leaks from entering the liquid path.
