Five models cover flowrates of 500–1,000 l/h. All units are factory tested and come with a validation pack covering installation qualification (IQ) and operational qualification (OQ). The system contains duplex softeners, a carbon pre-filter, low-pressure reverse osmosis modules, and a continuous electrodeionization (CEDI) unit with 10 or 18 cell pairs. The sanitization sequence is fully automatic, and CIP is easily carried out by following the prompts on the touch screen, the company says.
