Down Flow

Johnson Screens designs and manufactures a wide range of vessel internals for media retention in axial flow processes. These include support grids, distributor trays, quench pipes, transfer pipes, mixing assemblies, support structures, Vee-Wire^® scale traps, inlet distributors and outlet collectors. Everything you need to move, distribute and collect fluid flow through the vessel can be supplied and supported by Johnson Screens.

Because of their strength, durability and flow characteristics, our support grid and distributor tray systems are widely used in hydrotreaters, desulfurizers, hydrocrackers, molecular sieves, sand filters, gas sweeteners and other adsorption systems.
