The USI 3573 Multipurpose Vending Machine is a used, high-capacity unit that dispenses refrigerated and frozen foods from a single cabinet with a small footprint. Built by the Wittern Group, its next-generation airflow lets one machine vend sandwiches, salads, microwaveable meals, and ice cream through a common delivery area.
Two machines in one
The 3573 is field-convertible to fully frozen or fully refrigerated, and its airflow architecture supports both at once, so a single placement can carry fresh and frozen items together. With a glass-front design and up to 540 items in high-capacity configurations, it keeps an always-full appearance that drives sales. The price includes a coin mechanism, bill acceptor, and credit card reader for full cash and cashless payment.
