Jacket cooler/heater in specialty chemicals plant

Jacket cooler heater mini case story 640x360

Significant temperature and pressure changes caused frequent fatigue failure for the jacket heater/cooler used by a specialty chemicals manufacturing plant in Switzerland. By installing DuroShell, the plant has doubled uptime and cut maintenance time in half, thanks to DuroShell’s improved thermal fit combined with its exceptionally fatigue resistant design.

DuroShell offers more than just fatigue resistance when operating as a jacket cooler/heater.
With its low hold-up volume, it provides fast and accurate temperature control to maximize product quality and yield. The ability to operate with crossing temperatures also minimizes costs for steam or cooling water.  

Results

  • Double the expected uptime thanks to DuroShell’s exceptional fatigue resistance
  • Expected maintenance time reduced by 50%
  • Quick and accurate temperature control as a result of low hold-up volume
