Knitted Wire Demisters

TCI Demisters are made up from knitted materials with interlocking asymmetrical loops of metal or plastic with typical wire diameters being 0.1 - 0.3mm. By careful choice of wire diameter, Knitwire Products have produced knitted mesh demisters with extremely high free volumes (typically 98-99%) along with very high removal efficiencies and low pressure drop.

Along with wire diameter and mesh density, another important parameter in design and operation is the vapour velocity. This can be controlled by careful selection of the mesh area. Optimal area will depend on operating temperature, pressure and pressure drop. Under normal operating conditions, 99% + removal efficiency can be achieved with a pressure drop of less than 250 Pascals.
