Abstract: Atmospheric control valve device, part of an atmospheric control system built into a refrigerated container, whose installation requires minimal intervention and is self-sufficient, compact and reusable due to its long, cylindrical body that includes a battery compartment. The body also has a compartment for the electrical, electronic and sensor elements; a handling compartment for the elements that handle the device; a cover area to cover the container after removing the device; and a gas exchange compartment for two-way gas exchanges, controlled by a solenoid valve and by the differences in pressure that occur naturally within the refrigerated container.

Abstract: A hatch device comprised by a main support body, a flow guide piece and an optional plug, which allows for minimum modifications in the service hatch cover's structure during installation.
