A contacting grate or panel for mass transfer or heat exchange comprising a substantially rectangular supporting framework having two connecting frame members extending along opposite side edges and a number of elongate supporting frame members extending between the connecting frame members. A series of small, parallel plates are mounted along each of the supporting frame members and each plate is relatively short. The grate has two relatively large and opposite sides and the planes in which the plates lie are perpendicular to these two opposite sides. Preferably, each plate lies in a plane which extends at an acute angle of less than 90 degrees to a longitudinal central axis of its respectively supporting frame member. A number of these grates can be connected together at their corners to form a module.
