USI Mercato 4000 Snack Vending Machine – 32-Selection, iVend, New

USI Mercato 4000 Snack Machine – 32-Selection Ambient Snack Vendor

The USI Mercato 4000 snack machine is a front-loading, glass-front ambient snack vendor built by U-Select-It (USI) for small to medium indoor locations. Configured here with a 32-selection tray layout, it merchandises chips, candy bars, cookies, crackers, pastries and other shelf-stable packaged snacks behind a large LED-lit point-of-sale window, making it a straightforward, service-friendly choice for offices, break rooms and waiting areas.

This machine is the same platform sold under several names — the 32 Select Black Diamond Snack, WS4000 HR Series, SV28 and AB32 — so replacement trays, coils, motors and boards are widely stocked and easy to source. The Mercato 4000 chassis supports up to 53 selections at full configuration; the 32-selection build offered here strikes a practical balance of variety and footprint for the average single-machine account.

USI Mercato 4000 Snack Machine Specifications

Key Features

• iVend guaranteed delivery: an infrared sensor array confirms the product actually dropped — if it doesn’t, the customer’s money is returned, cutting refund headaches and service calls.
• Motor pairing for wide products: adjacent coils can be linked so the machine can vend oversized bags and wide items without jamming.
• MDB payment platform: ships with a coin mechanism and bill acceptor on the standard MDB bus, so a Nayax, USA Technologies or similar credit-card / tap reader drops in for cashless acceptance.
• Large LED-lit window: bright, low-draw LED lighting showcases product and improves selection at a glance.
• Configurable trays: spiral pitch and tray height adjust for chips, candy, crackers and pastries; splitting coils can double a selection’s count for thin products.
• Secure, serviceable cabinet: lockable powder-coated steel door with a front-loading layout that makes restocking and maintenance fast.

About U-Select-It (USI)

U-Select-It is a vending-equipment brand of The Wittern Group, a family-owned American manufacturer headquartered in Des Moines, Iowa, that has built vending machines in the United States for decades. USI is known for durable, easy-to-service snack and combo equipment backed by domestic parts availability and VendNet’s Des Moines-based technical support line — a meaningful advantage for operators who need parts and answers quickly. Because the Mercato 4000 has been produced under multiple badges over its run (Black Diamond, WS4000, SV28, AB32), boards, motors, coils and vend sensors remain some of the most cross-compatible and readily stocked in the snack-machine market, which keeps long-term service costs predictable.

Where This Machine Earns

The Mercato 4000’s compact 35-inch-wide footprint and ambient (non-refrigerated) design make it well suited to indoor, moderate-traffic locations: professional offices, employee break rooms, medical and dental waiting areas, auto-service lounges, small manufacturing floors, apartment community rooms and fitness studios. With 32 selections you can carry a broad snack mix without over-committing floor space, and because there is no refrigeration deck the machine runs quietly and draws little power.

As a general rule, a single well-placed ambient snack machine typically services a location of a few dozen to a couple hundred daily foot-traffic before a second unit or a combo machine is worth adding — pair it with a drink or combo unit where beverages are also in demand.

The iVend guaranteed-delivery system is especially valuable in unattended or after-hours locations, since it removes the most common source of customer complaints and lost sales: a product that hangs on the coil.

Frequently Asked Questions

How many selections does the USI Mercato 4000 have?

This unit is configured with 32 selections. The Mercato 4000 platform can be built out to as many as 53 selections, and coils can be split to increase count for thin products.

Does the Mercato 4000 take credit cards?

It ships with a coin mechanism and bill acceptor on the industry-standard MDB bus and is credit-card ready. A Nayax or similar cashless reader can be added at purchase or retrofitted later so the machine accepts tap, chip and mobile payments.

What power does it need?

The Mercato 4000 runs on a standard 110V AC, 60 Hz wall outlet. Because it is an ambient (non-refrigerated) snack machine, its power draw is low compared with a refrigerated drink or combo unit.

Will it fit through a standard doorway?

At about 35-5/32 inches wide the cabinet clears most 36-inch commercial and residential doorways. At 72 inches tall and roughly 34-1/4 inches deep it delivers upright on a curbside freight pallet; confirm your entry path and any tight turns before delivery.

Is this machine new or refurbished?

This USI Mercato 4000 is new and carries our full 2-year limited parts-and-service warranty for US customers.

How much does it weigh and how is it delivered?

Shipping weight is approximately 481 lbs depending on tray and option configuration. It ships as curbside freight on a pallet with free continental-US delivery. Review our Buyers Guide for placement and receiving tips.
