Half Open Pipe Inlet Device

  • Inlet Devices, Tower Internals
Half Open Pipe Feed Devices introduce process feed through an open section of pipe, spreading the incoming flow over a larger area and reducing the momentum associated with direct nozzle

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

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

Sieve Trays

  • Trays
Sieve Trays use a pattern of fixed perforations to disperse vapour through the liquid flowing across the tray, creating effective vapour-liquid contact for mass transfer. With no moving parts, their

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.

Spray Nozzle Distributor

  • Tower Internals
Spray Nozzle Distributors use a pressure-fed header and nozzle arrangement to provide controlled liquid coverage across packed beds and process vessels. Nozzle type, spray angle, spacing, and orientation are selected

Random Packing Bed Limiter

  • Packed Bed Internals, Tower Internals
Random Packing Bed Limiters are installed above the packed bed to prevent packing elements from lifting or becoming displaced during operation. Their open-grid construction securely retains the packing without unnecessary

Vane Inlet Device (RVID)

  • Inlet Devices
Vane Inlet Devices reduce the momentum of incoming multiphase streams while providing primary gas-liquid separation at the vessel inlet. The vane arrangement redirects the flow, separates bulk liquid, and distributes

Flashing Feed Chamber

  • Inlet Devices
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
