Dualflow Trays

Dualflow tray with vortex breaker

Dualflow trays are sieve trays without downcomer. The liquid passes the sieve holes - as well as the gas. This results in high turbulences. Because of this effect, dualflow trays are used for fouling applications. To ensure mechanical stability, dualflow trays have to be designed very accurately (Eigenfrequences).
