Abstract: There is disclosed a scrubber apparatus 300 for a refrigerated transport container 100 having a cargo space 105, comprising: a regenerating adsorber 302; a manifold 306, 308 in fluid communication with a first side of the adsorber, an interior gas port 318, 338 for fluid communication with interior gas in the cargo space and an exterior gas port 320, 340 for fluid communication with exterior gas outside of the cargo space; and a common actuator configured to actuate both an adsorption control damper 314, 334 for controlling selective fluid communication between the adsorber and interior gas, and a regeneration control damper 316, 336 for controlling selective fluid communication between the adsorber and exterior gas. There is also disclosed a scrubber apparatus 300 which is configured to heat interior gas provided to an adsorber for removal of a controlled gas. Methods of operating a scrubber apparatus are also disclosed.

Abstract: There is disclosed a refrigerated transport container 100 comprising: a cargo space 105 for containing an interior gas; a gas transfer membrane 230 configured to transfer component gases at different rates (such as carbon dioxide and oxygen), the gas transfer membrane having an interior side to receive interior gas from the cargo space 105 and an exterior side in communication with a gas exchange portion 250 of an exterior gas pathway 240; an air mover 244 configured to drive an exterior gas flow along the exterior gas pathway 240 for gas transfer over the membrane; and a flow controller 226 configured to selectively activate the air mover to control transfer of a controlled component gas across the gas transfer membrane. There is also disclosed a refrigerated transport container in which flow of exterior gas along an exterior gas pathway is heated prior to gas transfer at a membrane, and corresponding methods of operating a refrigerated transport container.
