Wittern 3575 Snack Vending Machine – MDB, Dual-Spiral Candy Shelves, Guaranteed Vend, Refurbished

Wittern 3575 Snack Vending Machine – Dual-Spiral Guaranteed-Vend Merchandiser

The Wittern 3575 snack vending machine is a full-size, commercial-grade USI snack merchandiser built for operators who want dependable multi-price selling without the babysitting that cheaper machines demand. This unit is configured with two dedicated candy shelves running dual snack spirals, so narrow candy bars, gum, and mints stay tightly indexed and drop cleanly every time. Behind the glass front sit six adjustable flex trays that hold snacks, candy, gum, mints, and pastries in a single cabinet.

With an MDB control board driving up to 40 numbered selections and iVend guaranteed-vend sensing, the 3575 is a machine you can place and trust. It suits any operator moving past small countertop or mechanical units into real, full-size commercial vending where one stop fills hundreds of packages instead of dozens.

Wittern 3575 Specifications

Key Features That Make the 3575 Earn

• iVend guaranteed vend: a delivery sensor confirms every product reaches the bin; if a package hangs, the machine re-attempts up to three times or refunds/prompts a new pick – no more “took my money” service calls.
• Dual-spiral candy shelves: two shelves double-index small candy and gum, packing more facings into the same footprint and reducing jams on thin product.
• Full MDB electronics: multi-price control board reads coin, bill, and card devices on the industry-standard bus, and prices each selection independently from the keypad.
• Six adjustable flex trays: reset motor spacing to match chips, bars, cookies, or pastries as your planogram changes.
• Large LED credit display & POS window plus all-steel, door-in-cabinet security for demanding public locations.

About USI & The Wittern Group

USI (U.S. Alliance / United Selection International) is the vending brand of The Wittern Group, a family-owned manufacturer based in Des Moines, Iowa that has built vending equipment in the United States for decades. Wittern-built snack machines like the 3575 are known for rugged all-steel cabinets, straightforward field service, and long parts availability – a big reason refurbished USI units stay in route service for many years.

Where This Machine Earns

The Wittern 3575 snack vending machine fits medium-to-high-traffic indoor accounts: office break rooms, warehouses and light manufacturing, hospitals and clinics, cafeterias, gyms, apartment clubhouses, and campus common areas. Its ~350–400 package capacity means fewer restock trips, and because you spend most of your time driving to a location, a full-size machine that empties out at a strong dollar per fill typically returns far more per visit than a small mechanical unit. Match the tray layout to what a given stop actually buys and let the guaranteed-vend electronics keep uptime high.

Frequently Asked Questions

How many selections and how much product does the Wittern 3575 hold?

The 3575 supports up to 40 numbered selections across six adjustable flex trays. As configured here with two dual-spiral candy shelves it holds roughly 350–400 packages; the platform is rated to about 630 items depending on tray setup.

Does the Wittern 3575 take credit cards?

Yes – the machine uses a full MDB control board, so it already runs a coin mechanism and bill validator and is credit/debit-card ready. A Nayax or similar MDB card reader can be added on the standard bus for tap and mobile-wallet payments.

What power does it need?

The 3575 runs on a standard 115 VAC grounded wall outlet – no special electrical service required for a typical indoor break-room placement.

Will it fit through a standard door?

At 41″ wide and 35″ deep it clears most standard 36″ doorways; measure your entry path and confirm the 72″ height clears low frames before delivery. Curbside freight drops the machine at the location.

Is this machine new or refurbished?

This is a refurbished unit – cleaned, tested, and guaranteed-vend verified – and it carries our 1-year limited parts-and-service warranty for U.S. customers.

How is it delivered?

It ships free via curbside freight from our Hanover, Minnesota facility, usually arriving in 3–7 business days after your 1–2 day processing window. See our Buyers Guide and browse more snack vending machines to compare models.
