Wedge Wire Support Grids for Tower Internals

High-Performance Wedge Wire Support Grids for Optimal Media Bed Retention

The Role of Support Grids in Reactors, Sieves, and Packed Beds

Support grids are essential components in reactors, sieve beds, and other media-filled vessels where catalysts, molecular sieves, or other packing materials must be securely retained. These support grids ensure structural integrity, prevent media loss, and maintain efficient process flow. Unlike off-the-shelf products, wedge wire support grids are custom-engineered solutions tailored to specific operational demands.

Wedge Wire Support Girds are each a custom-engineered design, not a commodity or off-the-shelf product.

Also referred to as packing support plates, these support grids serve two primary functions:

Structural Support – Withstanding both dead loads (the weight of the packed bed) and live loads (pressure differentials during operation).

Media Retention – Precision-engineered slot spacing prevents costly media loss while allowing optimal fluid distribution.

Given the high value and critical role of process media, proper support grid design is vital to operational efficiency and cost-effectiveness.

Types of Support Grids and Their Impact on Process Efficiency

Support grids come in various designs, each suited to different column diameters and process requirements. The ideal grid minimizes disruption to gas and liquid flow, particularly at the interface between the grid and the packed bed.

Poorly designed grids can lead to:

Flow channeling (uneven distribution)

Excessive pressure drop

Premature media degradation

To mitigate these risks, grids must be engineered with:

• Optimal open area for unrestricted flow
• Robust construction to handle mechanical stress
• Corrosion-resistant materials for long-term durability

In some applications, additional wire mesh layers are integrated to enhance filtration and media retention.

Key Design Considerations for Support Grids

When designing a support grid, engineers must account for multiple factors to ensure peak performance:

1. Packing Characteristics

Type (structured vs. random packing)

Particle size and density

2. Operational Loads

Static weight of the packed bed

Dynamic pressure fluctuations

Potential solids accumulation

3. Flow Dynamics

Gas and liquid distribution requirements

Acceptable pressure drop thresholds

4. Environmental Conditions

Temperature extremes

Corrosive or abrasive process media

By optimizing these parameters, support grids enhance process efficiency, reduce downtime, and extend equipment lifespan.

Applications of Packing Support Grids

Support grids are utilized across a wide range of industries, including:

• Sulfuric Acid Absorption Towers
• Drying & Cooling Towers
• Fume Scrubbers & Air Strippers
• Distillation Columns

Whether in chemical processing, petrochemical refining, or wastewater treatment, the right support grid ensures reliable media retention and optimal flow dynamics.
