An insulated chamber (1) for preservation and transportation comprises a container (2) of carbon dioxide snow provided with a lateral opening (5) permitting the injection, within the container, of liquid CO.sub.2 under pressure by a distribution device (10) connected to a source of liquid CO.sub.2 (6). The distribution device is provided with an electrovalve (18) controlled by a control block (19) comprising a timer permitting selecting the duration of injection of liquid CO.sub.2 into the container (2) to form there a controlled volume of carbon dioxide snow. The installation is useful for the preservation and transportation of fresh food products as well as frozen food products.
