Ever eaten a prepackaged salad? Chances are it travelled in one of these chilled boxes. The reefer unit takes up the first two feet of the container, leaving 46 feet of clear space for salad or potatoes. There are two major variations of these containers. Some have full panels around the reefer units. Some have open framing around the reefer unit. Both are equally easy to model. The set comes with two fully decorated injection molded container with weight capturing bottoms. It also comes with a pair of cast resin reefer units that can be user installed in about 20 minutes. The reefer unit is the same that many trucks use in over the road usage. Unlike their 40' counterparts, these containers carry fuel and power for their reefer units. If you look at the lower portion of the nose mounted unit, you will see a fuel tank. These containers carry the same kind of ISO style stacking frames at the 40 foot point. This makes it easy for them to stack on 40 foot or 20 foot containers as well as on top of another 48. The IBC (Inter Box Connector) points are set so that they match up to the seagoing standards. These container models, like all of the deLuxe container line, are available in pairs with 2 different road numbers.
