Refrigerated storage containers

Midstate Containers has been selling and renting out refrigerated containers to organic farmers, wineries, breweries, florists, butchers, schools, county fairs, meat processing plants, farmers market growers, dairies, biotech operations, and restaurants. 

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. 


Our insulated shipping containers are a refrigerated container with a non-working reefer unit. They are often used in hot weather climates, when third party cooling units are installed, or when storing produce, wine, or citrus is needed at a mild temp. 


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 reefers 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. 

Sizes available 

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

Power supply

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.
