A Freezer is a refrigeration unit designed to store food and other perishable items at sub-zero temperatures, typically ranging from -18°C to -25°C, to preserve them for a longer period. Freezers are widely used in restaurants, hotels, supermarkets, bakeries, hospitals, and food processing units. Unlike chillers, freezers maintain temperatures below freezing point, which helps prevent bacterial growth and extends shelf life. Most commercial freezers are constructed with a stainless steel body, heavy-duty insulation, and a powerful compressor for consistent cooling performance. Freezers are essential equipment in commercial kitchens to ensure long-term storage and food safety standards.
