Refrigerated and Insulated Containers


Midstate Containers has been selling and renting out refrigerated containers to businesses all across the state of California for well over 15 years. We've worked with organic farmers, wineries, breweries, florists, butchers, schools, hospitals, county fairs, meat processing plants, farmers market growers, dairies, biotech operations, restaurants, and much, much more.

All of our units have aluminum exterior paneling, high-density lightweight polyurethane foam wall construction, stainless steel interior walls and ceiling, and an aluminum T-rail floor. 


How are insulated storage containers different from refrigerated units? Our insulated shipping container units are a refrigerated container with a non-working "reefer" unit, meaning there is no working motor installed. What are they used for? Well, they are often used in warmer climates, when third-party cooling units are installed, or when produce, wine, or citrus is needed to be kept at a mild temperature, among other things. 

Why Shop With Midstate?


A shipping container is a much more affordable cold-storage solution than building a permanent cold-storage structure. Dollar for dollar, a portable refrigerated cargo container costs, on average, less than a third of what a new building would cost to construct. 


Not only are sea-train refrigerated containers more affordable, they are built to last a very long time (think over a decade at sea being exposed to the elements) and can be moved very easily (tow truck or forklift) from one site to the next, out of the way when not needed, and turned off and on with the click of a button. No site preparation is needed other than having a level surface and they can be delivered usually within a couple of days. 


Our units come in two sizes: 20' and 40' long. The 40' containers are readily available for purchase and rent. Our 20' units are currently not for sale and only available for rent.



Our reefers are most often equipped with Carrier or Thermo King refrigeration units and come with two main power supplies, 460v 3Ø and 220v 3Ø. We also have custom built units that work off of 220v 1Ø.
