Structured Packing Support Grid

  • Tower Internals
Structured Packing Support Grids provide a stable, level foundation beneath structured packing while maintaining a high open area for vapour flow and liquid drainage. Designed to carry the packing and retained liquid load without unnecessarily obstructing the column cross-section, they help preserve the hydraulic performance of the packed bed.

Flashing Feed Chamber

  • Inlet Devices, Tower Internals
Flashing Feed Chambers provide a controlled area for partially vaporised feed streams to enter a process column, allowing the vapour and liquid phases to disengage while reducing feed momentum. They help protect surrounding internals, limit entrainment and turbulence, and direct each phase into the appropriate section of the column.

ROSEPAK-S Smooth Structured Packing

  • Structured Packing
ROSEPAK-S™ Smooth Structured Packing features smooth corrugated sheets that minimise pressure drop, reduce liquid hold-up, and resist fouling by discouraging the build-up of solids and process contaminants. It is ideally suited to vacuum distillation, fouling services, and other demanding mass transfer applications.
