At Applied Chemical Technology (ACT), we believe in designing and fabricating industrial equipment with the highest quality standards. Our equipment is designed and fabricated by our team of engineers, designers, and craftsmen with experience in fluid bed applications and equipment design since 1981. Based on our understanding of fluid bed principles, we can size the correct piece of equipment for your process. We also have pilot plant facilities and equipment to test your continuous fluid bed process operating parameters. For clients interested in a complete fluid bed system, ACT has the expertise to design and fabricate the system for your processing requirements. We can include heat exchangers, air handling systems, feed systems, product handling, and more.

Our fluid bed heaters can also be designed as multi-function units. Through the use of zones in your fluid bed heater, we can coat, granulate, blend, and more. Our engineers can help you identify and test conditions to optimize your process.

What are the Benefits of Heating in a Fluidized Bed?

In a fluid bed heater, the material is suspended and mixed by the hot gases used to fluidized the material. This maximizes contact between the material and the hot gas providing heat transfer efficiency. The turbulent mixing in the fluid bed ensures that material is heated uniformly so hot spots do not form.

  • Efficient Heat Transfer
  • Uniform Heat Distribution
  • Gentle Handling of Product
  • Low Maintenance - no moving parts
  • Small Footprint
  • Low Capital Costs
  • Uniform Product Quality
