The Tech Inc. Hollow Fibre Coating Line for Composite Membranes adds a thin selective layer to a porous hollow fibre support. Fibre unwinds through a first dip bath, a vertical drying tower, a second bath (for interfacial polymerisation or a second coat) and a curing oven before rewinding.

Main components

Unwind and rewind stations with tension control
Two dip baths with guide rollers
Vertical drying tower with temperature control
Horizontal curing oven
Solvent extraction and covers
PLC and HMI

Applications: Thin-film composite NF and RO hollow fibres, PDMS and other gas separation coatings, pervaporation and hydrophilic coatings.
