A method is provided for operating a controlled atmosphere (CA) system to regulate the atmosphere in a cargo storage space. The CA system comprises a gas exchange module operable to vary the level of a component gas in the cargo storage space, a control module to control operation of the gas exchange module, and at least one of an oxygen sensor and a carbon dioxide sensor, each being operable to measure a parameter indicative of a level of oxygen or carbon dioxide respectively in the cargo storage space. The method comprises: the control module determining a respiration parameter value indicative of the rate of change of oxygen level and/or the rate of change of carbon dioxide level in the cargo storage space due to respiration of goods in the cargo storage space; and the control module controlling operation of the gas exchange module based on the determined respiration parameter value to target an oxygen level setpoint and/or a carbon dioxide level setpoint.

A system and method for maintaining a desired carbon dioxide concentration within an interior space of a transport unit during transport are disclosed. The method includes determining the carbon dioxide concentration within the interior space; enabling a carbon dioxide injection system when the carbon dioxide concentration is not at a set point value; and disabling the carbon dioxide injection system when the carbon dioxide concentration is at the set point value.

An internal air adjustment device supplies low-oxygen-concentration air to a storage, and maintains the oxygen concentration of internal air in a target oxygen concentration range that is lower than a reference concentration. The internal air adjustment device performs an oxygen-concentration restoration operation. The oxygen-concentration restoration operation is an operation of increasing the oxygen concentration of the internal air to the reference concentration from the target oxygen concentration range. In the oxygen-concentration restoration operation, a controller of the internal air adjustment device regulates the flow rate of external air that is supplied into the interior of the storage.

A storage assembly comprising a tank having a cavity defined by a wall including a sealable port for receiving and storing a perishable organic fluid within the tank, the perishable organic fluid being chilled prior to transfer to the tank; a heat exchange structure at least partially located between an inner and outer wall surface of the wall, wherein prior to receiving the perishable organic fluid the heat exchange structure is configured to chill the cavity; and a sparging structure located within the tank, wherein the sparging structure is in fluid communication with a source of conditioning agent, wherein the sparging structure is configured to: transfer a first portion of the conditioning agent into the tank to purge the tank prior to receiving the perishable organic fluid; and sparge and pressurise the perishable organic fluid with a second portion of the conditioning agent after transfer and sealing within the tank.

The protection process comprises transporting vegetable products (1) in an enclosure (3), a phyto-protective treatment being applied simultaneously by placing a quantity of a porous mineral or vegetable material (5) inside said enclosure (3), in which a liquid containing an essential oil or a constituent of an essential oil is absorbed; the porous mineral or vegetable material (5) having a liquid absorption capacity of between 5% and 30% by weight at 20° C.; the evaporation rate of the liquid absorbed in the porous mineral or vegetable material (5) being between 10 and 200 g per day and per kg of absorbed liquid at a temperature suitable for the preservation of the vegetable products and at atmospheric pressure; the porous mineral or vegetable material (5) being arranged inside at least one openwork container (7) allowing an internal atmosphere of the enclosure (3) to circulate through the openwork container (7) in contact with the porous mineral or vegetable material (5).

The invention relates to a reefer container (1) having a controlled atmosphere system (3) comprising:a first selective unit (4) comprising an absorber or a membrane (9) being selective for carbon dioxide over oxygen and nitrogen;a second selective unit (11) comprising an absorber or a membrane (14) being selective for oxygen over nitrogen; anda vacuum pump (6) for extracting and removing separated gasses from a permeate side (8, 13) of the first and second selective units (4, 11) to outside the container(1), where the system (3) is further comprising a pump (15) for providing an overpressure in the container(1). The pump (15) can be connected to the container (1) through a feed side (12) of the second selective unit (11). The invention further relates to a method of controlling reefer container (1) having a controlled atmosphere system (3).

A method for operating a container having a frame and a tank supported a distance from the ground by the frame so that a bottom side of the tank is accessible, includes connecting a protective gas line to a gas connection on the tank and applying pressure to the protective gas line before removing filling material from the tank so that protective gas can flow into the interior of the tank through a medium channel. A removal apparatus is connected to an opening of the tank and filling material present in the tank is removed from an interior of the tank through the opening. Data relating to a pressure of protective gas in the medium channel is detected by a pressure sensor at least during a time period of removing the filling material from the tank.

A fully self-contained, portable product dehydrator is provided comprising: an intermodal container housing an equipment module, the equipment module including a refrigeration equipment chamber proximate the front door and an air conditioning chamber behind the refrigeration equipment chamber, the equipment module retained in the interior and moveable from a retracted position to an extended position, wherein when in the extended position, the refrigeration equipment chamber is substantially exposed to an ambient environment, outside the front door; a heat pump dehumidifier including a subcooler, a desuperheater, electronic expansion valve and a compressor, housed in the refrigeration equipment chamber and at least two condensers and evaporator housed in the air conditioning chamber; a drying chamber, the drying chamber defined by the interior and the rear door; a motor control center; and a control panel; in electronic communication with the heat pump dehumidifier and the fans.

A system and its use for treatment of freight in a vacuum, having a chamber 1 for receiving a loaded container 9 having an external length CLa, an external width CBa and an external height CHa, wherein the chamber 1 has two side walls 11, 12 arranged opposite to a bottom 13 and top 14 and arranged opposite to a front wall 15 and back wall 16, and wherein a direction system XYZ is at right angles; and a conveying element 2 for parking and moving a container 9 relative to chamber 1 from a first position P1 outside the chamber 1 into a second position P2 inside the chamber 1; and a driving device 8 for moving between the first position P1 and the second position P2.
