Cool dollies are commonly used in air cargo services and it is mainly because they have to store the temperature sensitive goods in case if the warehouse is overloaded. Generally, they store the goods such as fresh fruits, flowers, fish, vegetables, meat, chocolates, frozen foods and pharmaceuticals inside a cool dolly. And also by using a cool dolly, it is easy to move temperature sensitive goods from one place to another place while maintaining the particular temperature level inside the cool dolly. So the goods inside the cool dolly will not get damaged even while moving because they seal it in a very safe manner which the external hotness is not entered into the cool dolly.
