Wedge Wire Support Grids & Vessel Internals
Engineered for extreme load-bearing environments. Our support grids provide superior media retention and uniform liquid/gas distribution for reactors, ion exchangers, and carbon towers.
The Foundation of Efficient Vessel Performance
A Wedge Wire Support Grid is the critical structural component in many process vessels. Designed to support heavy loads of catalyst, resin, or molecular sieves, these grids utilize the non-clogging V-wire technology to ensure a constant flow rate and prevent media loss.
Whether you require a single-piece construction for a small vessel or segmented panels to fit through a manway, our grids are custom-calculated for your specific pressure and weight requirements.
Advanced Features
Segmented Design
Specifically designed for easy installation. Panels are sized to fit through existing manways without welding the vessel shell.
High Load Bearing
Reinforced with support beams (I-beams or flat bars) to handle the weight of catalysts and pressure drops.
Low Pressure Drop
The high open area of wedge wire allows for efficient flow, reducing energy costs and process time.
Applications
Petrochemical
Catalyst support in hydroprocessing reactors and molecular sieves.
Water Treatment
Ion exchange underdrains and activated carbon filters.
Food & Brewing
Lauter tun false bottoms for efficient grain separation.
Mining
Resin-in-pulp (RIP) and resin-in-leach (RIL) processes.
