The patented multi-stage downcomer SUPERFRAC tray uses active and inlet area enhancements and the most advanced downcomer technologies. The
Enhancements page provides additional descriptions.
The trays are designed specifically for each application’s requirements.
The multi-stage downcomer uses the full vertical tray space, which minimizes downcomer limitations.
The additional liquid-handling capacity of the multi-stage downcomer can often eliminate the need for downcomer adapters.This reduces installation time and lowers equipment and field labor costs. It can also reduce downcomer backup by lowering the amount of liquid that must pass under the downcomer edge.
Capacity gains for these trays are substantial. At high capacities, testing has shown that these trays still maintain high efficiencies. Under most conditions, the efficiency of these trays is higher than conventional trays.
