<p>A packing unit (10) having a set of deflectors (16, 18, 30, 32, 118, 136) within a cage for deflecting each of two fluids moving through the unit, the deflectors being arranged so that in any image of the unit formed by parallel rays projected onto a plane, regardless of how the unit is oriented with respect to the plane, at least half of the area enclosed by the perimeter of the image will be a shaded area, no more than 35% of the shaded area being produced by surfaces of the deflectors oriented at more than 60o to the rays. </p> |
