The Johnson wire screen support grid grating is crafted from stainless steel, offering exceptional resistance to wear, corrosion, and clogging. The support grid is a trusted choice for industries that require efficient media support and high fluid or gas flow rates.
The Johnson support grids are available in various types and options, in single-piece or multi-section construction, for easy on-site assembly and can be easily retrofitted through existing manholes.
Features and Benefits of Support Grid Gratings
Johnson wire screen support grating is known for its high durability, structural integrity, and minimal maintenance needs.
- The support grid is made of wedge wire technology with an open surface area. It promotes consistent fluid distribution and prevents clogging, ideal for high-volume, continuous operations.
- This support grid offers a larger surface area and precise slot sizes to increase filtration efficiency, enhance flow rates, and reduce pressure drops.
Applications of Johnson Wire Screen Support Grids
This support grid is widely used across sectors, from petrochemical to water treatment to food processing and catalyst support in chemical reactors.
Common Installation Devices
- hydrotreaters
- desulfurizes
- molecular sieves
- gas sweeteners
- ion exchangers
- other absorption systems
For example, it supports catalytic media within reactors, ensuring even flow and optimal contact. In water treatment, Johnson support grids play a crucial role in solid-liquid separation, promoting cleaner output and reduced downtime.
Types and Customization Options
We can offer a variety of support grid configurations to meet the specific demands of different industrial applications. Options include flat, shaped, and radial designs tailored for unique vessel shapes and sizes. Customization is available in slot width, diameter, material composition, and grid height, allowing the grating to be adapted for specific operational needs and maximum performance efficiency.
Comparison with Traditional Support Gratings
Compared to traditional support grids, Johnson’s wire screen gratings provide significant advantages, such as improved media retention, even distribution of fluids or gases, and lower pressure drops.
The Johnson-shaped support grid, for example, optimizes bed capacity in curved vessel designs, maximizing media utilization and reducing dead zones often seen with traditional flat grids. This translates to better overall system performance and increased output.
Maintenance and Longevity
Minimal maintenance requirements make Johnson wire screen support grating a cost-effective choice. Its clog-resistant design ensures smooth operation and easy cleaning, while the stainless steel construction offers extended life even in corrosive environments. This long-lasting durability helps industries reduce downtime and maintenance costs, improving overall efficiency.
