FEECO Rotary Coolers

From pilot scale units, to commercial size coolers, we have the knowledge and experience to build a rotary cooler that’s right for you. FEECO’s rotary coolers are custom designed and built to meet the needs of your process. Whether you require short or long residence times, carbon steel or specialty steels, FEECO can design a rotary cooler for your application.

 

Rotary coolers work by tumbling material in a rotating drum in the presence of chilled or ambient air. The drum is set at a slight horizontal slope to allow gravity to assist in moving material through the drum. Lifting flights maximize heat transfer efficiency by lifting up material and dropping it through the chilled air as the drum rotates. Indirect water deluge coolers are also available.

FEECO Indirect Rotary Coolers

FEECO offers indirect rotary coolers for unique processing needs.

 

Indirect rotary coolers rely on heat transfer through the drum shell to cool material, utilizing cool water bathed over the drum as it rotates in order to cool the drum shell and subsequently the material within. This method, commonly called “indirect water deluge,” is ideal in situations where lightweight materials such as pigments or other powders could become entrained in the air stream of a direct cooler, resulting in product loss.

 

Another reason for utilizing an indirect rotary cooler is that it allows for keeping a controlled environment within the cooler, for example, in situations where material will oxidize or burn should it come into contact with air.

 

Indirect rotary coolers can be designed as part of a recycle circuit, where warm water coming off the drum is run through a heat exchanger to cool it and send it back to the beginning of the process. They can also be integrated into existing systems.

 

Indirect Cooler Features

  • Stainless steel shell to prevent corrosion
  • Custom design to suit exact processing needs
  • Increased efficiency with the use of a water deluge system
  • Various Drive Assemblies Available

Indirect Cooler Applications

  • Pigments
  • Ultra fine materials
