Refrigerated equipment, commonly known as reefer units, maintains controlled temperatures for transporting perishable goods. These units are vital in preserving the quality and safety of temperature-sensitive items such as food, pharmaceuticals, and chemicals during transit. Reefer units use advanced cooling systems, insulation, and temperature monitoring to ensure the cargo remains within specified temperature ranges. They find extensive use in the food supply chain, enabling the transportation of fresh produce, dairy, and frozen products across long distances. Reefer containers, trailers, and trucks are equipped with these systems, enabling industries to meet consumer demands for fresh products globally while preventing spoilage and maintaining product integrity.
