Field proven hardware, engineered to last

Half open pipe inlet device with flanged connection

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 discharge. Their simple, robust construction provides an economical feed inlet solution where more complex distribution equipment is not required.

Bubblecap Cartridge Trays

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.

MultiMister Technology For Gas Scrubbers

MultiMister Mist Eliminator

  • Mist Elimination
MultiMister™ Technology integrates cyclonic, vane, mesh, and fibre bed mist elimination into a single engineered system. By combining multiple separation stages, it efficiently removes a wide range of liquid droplet sizes while protecting downstream equipment and improving overall process performance.
