The bottom Spray Coater incorporates the Wurster Column principle within the fluid bed processor. The flow pattern of the product within the process chamber achieves a uniform and consistent coating using either aqueous or solvent based solutions or dispersions.

Spray Coaters are available as dedicated coating processors or multi processors having the capacity to top coat or spray agglomerate.

Spray Coaters are available in laboratory, pilot and production scale units. Direct scale-up between the units is achieved through the use of identical columns and spray systems.
