Weir-Trough Distributors

PTFE Weir-Trough Distributors are designed to span large diameter columns while providing an open area for high-volume vapor flow, and also handling a wide range of liquid flow rates.

The trough-type distributor can be constructed to fit packed columns with a diameter ranging from 36" to 60".
It is designed especially for distributing corrosive liquids over packing.

Each closed-end trough is engineered with the proper number of weirs to provide even distribution over a wide range of liquid flow rates. The spaces between the troughs provide for a large, open area required for high-volume vapor flow. Edlon designs a continuous support ledge to support the weir-trough. Edlon fabricates the weir-trough distributor by combining materials, such as virgin PTFE and PFA, in such a way as to ensure a sturdy and modular design with the mechanical strength and corrosion resistance required. The design can be produced in a modular form to facilitate on-site installation.

Other fluoropolymer materials, such as PVDF, ETFE, and ECTFE can be used as a construction material. The unique design provides the structural strength needed to maintain shape and stiffness at temperatures up to 175°C.
