JOHNSON SCREENS ®<br />

:<br />

Delivering the Future<br />

First<br />

<strong>Johnson</strong> <strong>Screens</strong> designs and<br />

manufactures a wide range of vessel<br />

internals <strong>for</strong> media retention. Amongst<br />

these innovative products is a line of<br />

internals used in down-flow or up-flow<br />

systems to retain the often-costly media<br />

and to provide a collection area <strong>for</strong> the<br />

process flow across the entire vessel<br />

diameter or length.<br />

Because of their strength, durability and<br />

flow characteristics, our support grid<br />

and distributor tray systems are widely<br />

used in hydrotreaters, desulfurisers,<br />

hydrocrackers, molecular sieves,<br />

sand filters, gas sweeteners and other<br />

absorption systems.<br />

<strong>Johnson</strong> screens have high open area, non-plugging slot design and present a stable, smooth<br />

interface with the media.
