Tower Internals

TOWER INTERNALS

Tower internals cover structured/random packing, demisters/mist eliminators and tower fittings (liquid distributors, trays, supports). We design and manufacture all in-house, ensuring matched performance of the whole tower.

Tower internals: baffle plates, distributors, trays, wire mesh packing, perforated plate packing, random packing

Packing

PACKING

Structured packing: wire gauze (AX/BX/CY) & perforated plate (125Y–500Y); CY reaches 8–10 theoretical plates/m, close to imported performance. Random packing: metal & plastic series for distillation, absorption, stripping, extraction.
