H. J. Heinz has installed a SCALEwatcher ENiGMA System from Environmental Treatment Concepts on to a 150mm return line to a Retort Cooker used for pressure cooking container products such as Ketchup and Soup.

The return line recycles water at a temperature of 140°C through the unit.

Until the SCALEwatcher ENiGMA System was fitted the Retort Cooker continually scaled-up increasing fuel costs and requiring continual chemical treatment at a cost of approximately £2,400 per week.

Additional on-going costs were incurred in labour charges to clean the product containers that had become stained and marked during the water conditioning process.

Within two weeks of SCALEwatcher ENiGMA being installed, large quantities of scale were being removed daily from the cooker and piping system and within a few weeks the system was completely scale free. Chemical treatment has now been discontinued, and the Electronic Descaling System has provided a payback to Heinz in less than 3 months on energy savings and chemicals alone.
