Commercial refrigeration is designed to preserve food at low temperatures, aiming to increase its shelf life and maintaining its quality. Typically, it uses medium-to-small-sized refrigerated units for refrigerating or freezing food and products that require storage or processing under low-temperature conditions. This type of refrigeration is primarily used in the hospitality and catering industries, as well as in shops, supermarkets, butcheries, fruit and vegetable businesses, and dairy stores intended for retail sale.
