Central Dialysis Water Sytem

    Central Dialysis Water Sytem

    CWP Dialysis Water System

    5,000 to 13,000 GPD w/ Heat Disinfeciton

    The CWP 100 offers cost-effective, consistent delivery of AAMI grade water according to ANSI/AAMI 13959 for dialysis at the point of use. This system is designed to meet all current standards for dialysis quality water. The automated heat disinfection of the distribution loop simply and easily reduces biofilm development and minimizes levels of endotoxin, fungi, yeast and other microbial contaminants.
