A heat transfer enclosure for receiving articles to be processed or stored under conditions of reduced temperature, comprising one or more members of thermally conductive material having a thermal conductivity of at least 10 Wm-1 K -1, said one or more members having a contact surface for contacting articles located in the enclosure and including projections extending generally away from said surface;wherein in use heat is conducted between a said article contacting said contact surface with an upper 10 surface of said article and a heat exchange fluid in said heat transfer enclosure via an article--contact surface--projections--heat exchange fluid heat transfer path. |
