Tru-Scan™ and Tru-Grid™ scans are powerful tools that give you valuable insights into packed and trayed towers, tanks, pipes and more. Using this field-proven predictive maintenance technique on distillation columns allows plant personnel to monitor tray or packing hydraulics. A sophisticated monitoring programme can track the effects of fouling or other incapacitating conditions to extend run times and identify maintenance requirements in advance of scheduled turnarounds.
