Retail operations such as grocery stores, convenience stores and gas stations also use many different kinds of freezers and coolers within their operations. Some of these implementations include glass door coolers for beverages, walk-in beverage storages, deli cases, fish coolers, blast chillers, ice makers and freezers, and also floral coolers. Each one of these freezers and coolers depend on staying at a deliberate temperature to ensure the intended product keeps fresh for a long period of time.
