Dialysis Water Distribution Loop (DWDL)

The Dialysis Water Distribution Loop (DWDL) is an integrated heat disinfection system designed for reliable and safe dialysis water delivery. It allows flexible scheduling with adjustable operation by day, heating intervals, holding times, and disinfection temperatures. All disinfection cycles are controlled, recorded, and stored for full traceability. DWDL systems are engineered in compliance with ISO 23500 and AAMI RD62 standards, ensuring consistent ultrapure water quality for dialysis centres.
