Travelling Caul Screens are created from synthetic, metallic, spiral and ceramic materials. They are for forming, conveying and liquid filtration applications.

Traversing Thermal Transfer Printers utilize print head consisting of a linear array of heating elements. It offers a most important advantage over die cast image transfer techniques, in that images transferred by thermal transfer printing. These are designed for multiple-lane, horizontal or vertical form, seal machinery, blisters, packaging systems and horizontal continuous flow wrap equipment.

Tray columns are cylindrical vessels where liquid and gas flow in a counter-current or in a cross-current configuration and can be operated under pressure. Matter exchange occurs on a series of metal trays or plates. Tray columns can be classified depending on the flow configuration of the streams in the internal plates. Mainly two different types of column can be identified such as counter-current columns and cross-current columns. In counter-current columns, gas and liquid flow through the same perforations. The tray occupies the whole section of the column. In the cross-current plate, the liquid flows on the plate and goes down through a down comer.
