Disclosed herein are methods, systems, and devices for preventing condensation during shipping of prefabricated electrical equipment within a plurality of enclosures. In one embodiment, the system includes a first enclosure first monitoring sensor configured to be positioned within a first enclosure of the plurality of enclosures, and a first enclosure climate control device configured to be positioned at least partially within the first enclosure. The system also includes a first enclosure primary side electrical interconnect, a first enclosure secondary side electrical interconnect, and a first enclosure controller. The first enclosure controller is coupled with the first enclosure first monitoring sensor, the first enclosure climate control device, the first enclosure primary side electrical interconnect, and first enclosure secondary side electrical interconnect.

The present invention provides a system (1) to prevent the formation of fuel vapors comprising a containment tank (10) and a variable volume tank (12) accommodatable within the containment tank (10), wherein the variable volume tank (12) is configured to receive liquid fuel. Our invention can be used in any tanks or reservoirs of liquid products that attack the ozone layer, preventing the formation of vapors that are extremely harmful to nature and the environment.
