A term used in reference to a refrigerated container to indicate it is a type that permits the temperature within the container to be controlled. The reason that this is important is so a gas such as nitrogen can be maintained in a stable condition within the container. Nitrogen reduces the spoilage rate of fruits and vegetables.

Sophisticated, computercontrolled systems that manage the mixtures of gases within a container throughout an intermodal journey reducing decay.

Any gas or mixture of gases that prevents or retards oxidation and decarburization.

A type of atmosphere, eg a mixture of nitrogen and hydrogen, which is used in a heat treatment furnace to prevent unwanted reactions such as oxidation or decarburisation occurring to the work piece.

Sophisticated, computer-controlled systems that control the mixture of gases within a container throughout an intermodal journey.

An atmosphere in which the levels of oxygen, carbon dioxide and nitrogen, as well as temperature and humidity, are monitored and maintained.

A gas or mixture of gases in which steel is heated to produce or maintain a specific surface condition. Controlled atmosphere furnaces are widely used in the heat treatment of steel as scaling and decarburization of components is minimized by this process.

A controlled atmosphere is an agricultural storage method. An atmosphere in which oxygen, carbon dioxide and nitrogen concentrations are regulated, as well as temperature and humidity.
