To reach store shelves, perishable items often embark on an extensive journey across states and even continents. Making this all possible are cold chain systems with uninterrupted series of cold storage and food distribution activities. The development of the system opened the doors to new markets in multiple industries, making it an export success. The U.S. food industry spends millions each year on moisture control and climate control solutions that allow businesses to prosper. As a result, cold chain systems are vital to global trade and the availability of food around the world.
