Indirect Rotary Drum Coolers

Rotary Drum Coolers and Cooling Systems for Indirect Cooling

At Applied Chemical Technology (ACT) our indirect rotary coolers (water deluge or water jacketed) are backed by a team of engineers, designers, and craftsmen with experience in designing and building industrial equipment and processes dating back to 1981. Over the years, our rotary cooler designs have proven themselves to be a high quality, efficient, and rugged solution for our clients’ thermal processing systems. If your cooling process requires protected atmospheres, gentle handling, or fine powders; one of our indirect coolers can meet your needs.

Our engineers can help you identify the best drum internals for your rotary drum cooler based on your material properties and processing goals. ACT has the expertise and equipment for bench scale or pilot testing to generate the data needed to size your cooling drum. We also can design and engineer a complete thermal processing system for your cooling needs. This may include heat exchangers, chillers, material handling systems, and more.
