Cartridge 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.

Compact Tray Assemblies for Easy Installation and Maintenance

Cartridge Trays are complete tray assemblies designed to be installed into a column as modular sections, simplifying installation, maintenance, and replacement. Rather than assembling individual tray panels and hardware inside the vessel, the tray components are pre-assembled into a cartridge arrangement that can be inserted into position as a unit.

This design is particularly useful where access inside the column is restricted or where minimising installation time is important. By reducing the amount of assembly work required within the vessel, Cartridge Trays can help shorten maintenance shutdowns and simplify future inspection or replacement.

Cartridge Tray assemblies can incorporate a range of tray technologies, including sieve, valve, or other mass transfer tray designs, depending on the hydraulic and process requirements of the column. Each assembly is manufactured to suit the vessel diameter, support arrangement, tray spacing, and operating conditions.

Suitable for both new equipment and retrofit applications, Cartridge Trays provide a practical solution where installation efficiency and maintainability are important considerations.
