For special customer requirements and/or performance, AMISTCO Separation Products, Inc. offers numerous tray performance enhancing features. Some of the most common features offered by AMISTCO include:
Cartridge Trays Suitable for small diameter body flanges. Can provide up to 5 trays per cartridge. Different sealing options are available.
Anti-Jump Downcomer Baffles To prevent liquids flowing across the tray from jumping over the downcomer onto the opposing flow path. Anti-Jump Downcomer Baffles are standard for multi-pass trays with center and off-center downcomers.
Picket-Fence Weirs These are used to decrease the effective weir height. This is for low liquid flows, and using this option will help increase the effective liquid height and prevent blowing.
Splash Baffles For low liquid rate services, Splash Baffles serve to maximize the liquid retention time on the trays. They can be used in place of, or in conjunction with, picket fence weirs. Splash baffles are located adjacent and parallel to the outlet weir. They clear the tray deck and outlet by 1/2” to 1” forcing the exiting liquid to flow under the baffle before it flows over the top of the outlet weir.
Swept-Back Weirs To reduce the effective liquid height on the tray by lowering the volume of liquid per unit length flowing over the outlet weir. This option should be considered for high liquid flow rates.
Swept-Back Weirs - are used on side downcomers. They can also be used to balance weir loads between side and off-center downcomers in multi-pass tray designs.
Sloped Downcomers with Recessed Inlet Sumps Suitable for heavy liquid loads that could otherwise cause downcomer flooding.
