1. A mixer box comprising:
a first duct that includes
an upstream end and a downstream end, along a first axis, that are both open to form a first flow path through the first duct along the first axis,
a first side and second side, along a second axis that is perpendicular to the first axis, the first side comprising one or more openings, and
one or more mixers that each extends along the first axis between the upstream end and the downstream end, and extends along the second axis between the first side and the second side, such that the first flow path is divided into a plurality of channels,
wherein each of the one or more mixers has an open end, at the first side, that is aligned with one of the one or more openings in the first side, such that a second flow path, perpendicular to the first flow path, is formed through the first side into a hollow interior of the mixer, and
wherein each of the one or more mixers includes two side surfaces, each of the two side surfaces including a plurality of apertures that decrease in area as a distance from the open end of the mixer increases, each aperture forming a flow path between the hollow interior of the mixer and one of the plurality of channels.
