Method and system for inlet temperature monitoring for centralized heat disinfection of dialysis machine inlet lines

A dialysis system with centralized heat disinfection control, comprising:

• a central water processing system comprising a temperature controller;
• a plurality of dialysis machines having fluid inlets which comprise temperature sensors for sensing water temperature;
• a fluid supply loop capable of circulating heated water from the central water processing system to the fluid inlets of the plurality of dialysis machines and back to the central water processing system, wherein the at least one temperature sensor senses temperature of fluid supplied from the loop to the fluid inlets;
• and
• a process controller is capable of (a) receiving data on sensed temperatures from the temperature sensors at the fluid inlets of the dialysis machines, (b) comparing the sensed temperatures to a predetermined value or value range selected for disinfection, and (c) issuing an alarm or controlling the temperature controller for adjusting water temperature of water at the central water processing system when a sensed inlet water temperature of a dialysis machine does not meet the predetermined value or value range, or both.
