Countertop display refrigerators are an attractive and practical solution to cold food and beverage storage. Also known as countertop merchandisers, they are usually found in commercial kitchens and dining areas as well other retail environments. Because they are particularly effective in boosting impulse sales, they are often used as promotional tools. These appliances feature transparent glass doors allowing for maximum visibility of the contents while maintaining a controlled temperature inside. Typically, countertop display refrigerators have one or two doors that either swing or slide open, making them ideal for self-service. Adjustable temperature controls can be used to keep food and drinks well within the proper food safety zone, between 33 and 39 degrees Fahrenheit. There are also freezer models that can reach temperatures as low as -10 degrees Fahrenheit. Internal evaporators and condensers promote faster cooling, therefore leaving little worry in regard to temperature recovery after repeated opening of the doors. Available in many styles and sizes, countertop display refrigerators are both versatile and sure to get noticed.
