Stainless steel liquid distributor is a metal, trough-type unit that meters the feed liquid out across the face of a packing bed. It is not a flat pan but a rank of parallel open channels — troughs — carried across the tower on a frame. Liquid poured into the troughs escapes along their length through V-notches or weirs in the walls, or through drip tubes in the base, arriving on the bed as a close grid of small, matched flows; the vapour climbs the tower through the broad lanes left open between the troughs. The point of the trough shape is fouling resistance: its openings are wide and drain themselves, so thick, particle-laden or fast-flowing liquids that would silt up a drilled distributor keep running. Welded from 304 or 316 stainless, it is robust and copes with heat and duty a plastic unit could not; ceramic serves where temperatures are very high and PTFE where the liquid is savagely corrosive. It stays even as the flow swings across a ten-to-one band. Model RJ-2841.
- Metal trough distributor: open channels meter the feed liquid across the bed.
- Liquid exits by notches, weirs or drip tubes; vapour climbs the lanes between troughs.
- Wide, self-draining openings resist fouling — made for viscous liquids and high loads.
- Welded 304 / 316 stainless; ceramic for very high heat, PTFE for savage corrosion.
- Even across a ten-to-one flow swing; model RJ-2841.
