Our 20ft refrigerated containers are perfect for lower volume needs (1000 cu ft) temperature controlled storage. The cooling units control the internal temperature at set points between -20 and +80 degrees Fahrenheit. They require a 3 phase electrical connection. While most customers use these boxes for freezing or chilling products they can also be used to keep products at a constant temperature up to 80 degrees. Our customers store everything from ice cream to pharmaceutical products. We sell units with a 90 day warranty, ask about details.
