Laboratory Fluid Beds

Applied Chemical Technology’s (ACT) 100N and 300N Laboratory Fluid Beds offer the perfect solution for testing or developing chemical products and processes. These versatile units are easy to use and suitable for applications from industrial chemicals and powders to foods and nutraceuticals.

With an ACT Laboratory Fluid Bed you can easily experiment with fluidization velocities, operating temperatures, coating methods, drying, agglomeration, and cooling curves along with other process variables. The 100N and 300N Laboratory Fluid Beds are also ideal for batch production runs and product evaluation. In addition, all data is directly applicable for scale up to ACT’s industrial fluid bed systems.

Applications Suited for Fluid Beds:

  • Drying
  • Coating
  • Agglomerating
  • Granulating
  • Impregnating
  • Heating
  • Reacting
  • Mixing
  • Classifying
  • Cooling
  • Decontaminating

Materials of Construction: Stainless Steel/Plexiglas
Product Bowl Volume: 5 Liter (Model 100N) or 20 Liter (Model 300N)
Inlet Air Temperature: Up to 250°F


Model 100N Laboratory Fluid Bed System

Model 100N Fluid Bed System

The 100N is a multi-purpose bench-top fluid bed that is designed for small scale spray coating, granulation and drying of particulates and powders.

Model 300N Laboratory Fluid Bed System

Model 300N Fluid Bed System

The 300N is a multi-purpose fluid bed that is 4X larger than the 100N model specifically designed for small to intermediate scale spray coating, granulation and drying of particulates and powders.

Drying Diagram


Heated air passes through the fluidized particles to remove moisture rapidly and efficiently. The process can use lower temperatures than conventional methods.

Granulating Diagram


Spraying a binding agent into a fluidized powder produces particles with very uniform size, weight, and shape. The fluid bed may also be used as a dryer once the desired particle size is reached.


Coating Diagram


Liquids are easily sprayed onto fluidized particles from the top or bottom, producing an even and uniform coating.

Standard Features of ACT 100N and 300N Fluid Beds

Our standard 100N and 300N model fluid beds come with removable acrylic upper chamber, stainless bowl with handles, removable stainless steel distributor plate (6.33% open area), polyester exhaust or pleated cartridge air filters with stainless steel clamps, stainless steel wire frame filter support and replaceable inlet air dust filter. The spray system also includes nozzle, air cap, fluid tip, manual tip cleaner, extension, tubing, compressed air connectors, air pressure regulator and air pressure gauge. All necessary seals, clamps and gaskets are also included.
