This is a SNACK VENDING MACHINE made by Dixie Narco. This style is actually a Hershey model.
DN7000CVHE/SII/10 or often misread as DN7000 CV HE - 511 - 10
10 Selection refrigerated Candy Vending Machine with spirals inside just like a normal glass front vender would have.
The 5 Shelves may have various combinations of 6 Snack spirals and 10 Candy spirals, combining to have as many as 50 rows of candy holding 15 per row for a total of over 750 items to sell. However the SII computer programs multiple rows down to only 10 selection buttons.
These models are often used poolside, at carwashes, or outside malls. There insulated case works quite well even in direct sunlight to keep the candy from melting, the only drawback to it is people cannot see which products are inside the machine and have to rely on the selection button labels themselves.
An electronic eye, or drop sensor makes sure that each customer gets an item or a refund.
the SII controller supports most MDB Coin Mech's and Bill Validator's or Recyclers and of course Credit Card readers.
