C-PAK Random Packing

Random Packing

C-Pak™ Random Packing utilises a Cascade Mini Ring-style geometry with a compact 1:3 aspect ratio to maximise surface utilisation and improve vapour flow. The result is higher hydraulic capacity, lower pressure drop, and efficient mass transfer in distillation, absorption, and stripping applications.

Cartridge Trays

Tower Internals, Trays

Cartridge Trays are modular, pre-assembled tray systems designed to simplify installation and replacement inside process columns. Their compact construction reduces internal assembly work and makes them particularly useful for restricted-access vessels, small-diameter columns, and retrofit projects where minimising shutdown time is important.

Catalyst Outlet Collector

Reactor Internals

Catalyst Outlet Collectors gather gas or liquid leaving a catalyst or adsorbent bed and direct it towards the vessel outlet while retaining the bed media. High open-area screening provides an efficient collection path with minimal flow restriction, helping prevent catalyst carryover and protect downstream equipment.

Catalyst Support Grid

Reactor Internals

Catalyst Support Grids provide the structural foundation beneath catalyst and adsorbent beds, carrying the weight of the catalyst and support media while maintaining a high open area for process flow. Grid and beam arrangements are designed to provide the required mechanical strength without unnecessarily restricting gas or liquid passage through the vessel.

Fixed Valve Tray Technology

Trays

Fixed Valve Trays use permanently formed openings in the tray deck to direct vapour through the flowing liquid, combining effective mass transfer with a simple, robust construction. With no moving valve components, they are particularly suited to high-capacity, fouling, and demanding process services where mechanical reliability is important.

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.

Floating Valve Tray Technology

Trays

Floating Valve Trays use movable valves that rise and fall in response to vapour flow, automatically adjusting the available flow area as process loads change. This self-regulating action provides good turndown, reduces weeping at lower vapour rates, and maintains effective vapour-liquid contact across a wide operating range.

Gasumax Cyclones

Mist Elimination

GasuMax™ Cyclones use centrifugal force to separate entrained liquid droplets from gas and vapour streams. Designed for high gas velocities and heavy liquid loading, they provide reliable mist elimination with no moving parts, making them ideal for gas-liquid separators, scrubbers, and process vessels.
