Flow Equalization Baffles: Flow Range 0.1-100 L/min per outlet

Component Specifications

Definition

Flow equalization baffles are precision-engineered internal structures installed within flow distribution manifolds to mitigate flow maldistribution. They function by creating controlled resistance paths that balance pressure drops across parallel channels, ensuring each outlet receives consistent volumetric flow regardless of positional effects or upstream disturbances. These components are critical in applications requiring precise fluid delivery, such as chemical reactors, heat exchangers, and coating systems.

Working Principle

Flow equalization baffles operate on the principle of controlled flow resistance. By strategically placing baffles with specific geometries (such as perforated plates, vanes, or labyrinth paths) within the manifold, they create differential pressure zones that compensate for natural flow imbalances. This ensures that fluid takes longer paths to outlets with lower resistance and shorter paths to those with higher resistance, resulting in uniform exit velocities and flow rates across all distribution points.

Materials

Typically constructed from corrosion-resistant materials: Stainless Steel (AISI 304/316), Aluminum Alloys (6061-T6), Plastics (PTFE, PVC, Polypropylene) for chemical compatibility, or Composite Materials for specialized applications. Material selection depends on fluid properties, temperature range (-40°C to 200°C), and pressure requirements (up to 100 bar).
