A refrigeration unit designed to display perishable goods without doors or covers, allowing customers direct and immediate access to products, defines this type of commercial equipment. These units typically utilize a constant flow of cold air to maintain food-safe temperatures while presenting items such as beverages, produce, and grab-and-go meals. A common example is the refrigerated display case found in grocery stores showcasing pre-made salads near the checkout lanes.
This equipment offers several advantages, including enhanced product visibility, impulse purchase encouragement, and reduced energy consumption compared to enclosed models (depending on design and usage). Historically, the open design has been favored for its convenience and marketing appeal, driving sales by making items more accessible and visually appealing to shoppers. Early iterations were less energy-efficient, but modern engineering focuses on balancing accessibility with sustainable operation.
