Avoided Cost-Repair of Failed Dryer Heat Recovery Coil

During the course of a facility assessment at a food ingredient manufacturer, replacement of a failed heat recovery coil was identified as a potential project. The coil was one of four installed on a “runaround loop” used for preheating process inlet air with hot process exhaust. Due to age, one of the coils had developed leaks was in need of replacement.

Assessment indicated that replacement of the failed coil would not have favorable economics. The estimated savings was only about $1,500 per year, providing a simple return of almost 20 years.

while repair of the failed coil was not favorable with the current configuration, other opportunities were suggested to help justify coil replacement. Kinergetics’ involvement saved the company the time and expense related to replacement of a failed component that would have done almost noting to improve competitiveness.
