These are typically available in 20′ 24′ & 40’hc with stainless steel flooring, stainless steel exterior / interior walls, most of all they are insulated. They are offered as non working or working refers. The non working means the motor is no longer working and sold as just a insulated container. The working models are obviously working and can be cooled or controlled to go below freezing via electricity not gas or diesel. If you need the specifics on the container please feel free to ask about the current model we are offering. Sometimes there is a shortage on these & we will have to wait for them to come in off the ships to we deliver them. If we do have them we are almost always the cheapest non greedy company to sell them.
