Custom designed three-stage heat exchanger can be used to increase the temperature of a 25,000 scfm airflow from 50 to 330°F (10 to 166°C) using 145 psig steam.

Heated air dries the crumb rubber during processing. The design uses seven identical internal cores, each with two stacked steam circuits, split between three housing boxes to ease handling, and core swapping, if required. The split design also provides the ability to use standard modes of shipping. Using identical cores reduces parts inventory. Each of the three stages is approximately 7 by 8'.
