Internals for Down Flow Reactor

Johnson Screens designs and manufactures a wide range of vessel internals for media retention. Amongst these innovative products is a line of internals used in down-flow or up-flow systems to retain the often-costly media and to provide a collection area for the process flow across the entire vessel diameter or length. Because of their strength, durability and flow characteristics, our support grid and distributor tray systems are widely used.

The uniquely designed StaySafe™ Manway Hold-Down Screen keeps workers safe by not requiring entry into potential hazardous, confined space. The center locking bar integrated in the manway is released with a single tool. Facilitates the manway to be captured by two lifting hooks for control of the manway either being set-aside inside the vessel or removed from the vessel entirely.

The uniquely designed StaySafe™ Floating Hold-Down Screen keeps workers safe by not requiring entry into potential hazardous, confined space. The center hub unlocks all screen components with a single motion, allowing the capture tabs to facilitate secure removal from the vessel from over 6’ away, through the manway of the vessel.

The design for the Spider Lateral builds on decades of success of other Johnson Screens header lateral systems, introducing angled arms to fit the curvature of the vessel head.
