USI 3535 Mercato Snack Vending Machine – 5-Wide, iVend Guaranteed Delivery, Refurbished

Refurbished USI 3535 Mercato Snack Machine – iVend Guaranteed Delivery, 5-Wide Capacity

The USI 3535 Mercato snack machine is a five-wide, glass-front snack vendor engineered by USI/Wittern for medium-to-high-volume indoor accounts. It pairs a deep, flexible product bay with iVend™ Optical Sensing, an infrared drop-detection system that confirms every purchase actually falls to the delivery bin — and issues an automatic refund or free re-vend if it doesn’t. That single feature cuts customer complaints, chargebacks, and service calls, which is exactly what a route operator wants from an unattended machine.

This unit has been professionally refurbished: inspected, cleaned, and tested to reliable working condition so it performs like new at a fraction of the cost of a factory-fresh machine. In a standard tray layout the USI 3535 Mercato snack machine offers roughly 40 selections — typically split across chip/pastry rows and candy/cracker rows — and the ambient (non-refrigerated) cabinet handles chips, crackers, cookies, pastries, candy, gum, and mints with ease.

Because it is a 5-wide (five-tray-column) cabinet rather than a narrow 3- or 4-wide unit, the 3535 gives a location the product variety of a bigger footprint while still fitting against a single wall. Deep spiral columns hold multiple facings of each item, so high-demand snacks stay in stock longer between service visits — fewer trips for the operator and fewer sold-out coils for the customer. It’s a machine designed to run quietly in the background and simply not cause problems.

USI 3535 Mercato Specifications

Key features that make money on location

• iVend™ Optical Sensing: optical sensors verify the product cleared the spiral and dropped; if it hangs, the shopper is refunded or invited to pick again automatically — no lost sale, no angry note taped to the glass.
• First-in / first-out vend sequence: each column rotates stock so older product sells first, keeping snacks fresh without manual rotation.
• Dual-spiral delivery: lets you pair two products in a single row for wider variety in the same cabinet.
• MDB + DEX intelligence: plug in a coin changer, bill validator, and a modern card reader; DEX pulls sales data for route accounting and telemetry.
• ADA-compliant & LED-lit: reachable keypad and delivery bin plus bright, low-draw lighting that shows product well in break rooms and lobbies.

About USI / Wittern

The USI 3535 is built by USI (Wittern Group), a family-owned American manufacturer based in Clive, Iowa that has produced vending equipment since 1931. Wittern engineers the iVend guaranteed-delivery platform in-house and supports its machines with widely available parts and service documentation — a big reason USI snack machines are a favorite for operators who want long service life and easy repairs.

Where this machine earns

With a five-wide footprint and roughly 40 selections, the USI 3535 Mercato snack machine fits accounts that see steady foot traffic but don’t need a warehouse-sized bank of machines: corporate break rooms, manufacturing floors, schools and universities, hospitals and clinics, apartment community rooms, gyms, and busy waiting areas. The ambient cabinet means no compressor and low power draw, so placement is flexible — anywhere with a standard outlet and a level floor. Snack machines typically pair well with a drink machine on the same wall; browse more options in our Snack Vending Machines category, and new operators can plan placement with our Buyers Guide and Vending Startup Program.

USI 3535 Mercato snack machine FAQ

How many selections does the USI 3535 Mercato hold?
In a standard tray layout it offers roughly 40 selections across five adjustable trays; the exact count depends on how the snack and candy shelves are arranged (commonly 4 snack / 2 candy or 5 snack / 1 candy).

Does it take credit cards, or can a Nayax reader be added?
Yes. The machine is MDB + DEX and card-reader ready, so a Nayax or similar cashless reader mounts directly and works alongside the coin mechanism and bill validator.

What power does it need?
A standard 115V, 60Hz grounded outlet. It’s an ambient snack machine with no compressor, so power draw is low.

Will it fit through a standard door?
At about 41.4″ wide it is wider than a typical 36″ doorway, so plan delivery through a double door, dock, or wide entrance. It stands about 72″ tall and 34.75″ deep.
