SPECIFICATION 

 

The 

Heatsan 

Integrated hot water disinfection unit incorporates 

equipment to heat water received from a water purification system and 
circulate around a distribution loop at a controlled sanitizing temperature 
for a specified length of time. On completion of disinfection the water is 
then made available to be taken off to dialysis machines for their heat 
disinfect cycle. At the end of the cycle the water is discharged from the 
system to drain and the loop is cooled. 

 

Models available:  
 
 

00HS208 

 

3-phase, 208V, 60hz, 15kW Heater 

 

 

Controls 

 

All the processes of the 

Heatsan 

unit are controlled automatically and

 

the unit operates via a touch screen which displays systems 
performance data and unit status. 
 

 

Alarms and Maintenance 

 

The 

Heatsan 

unit incorporates monitoring devices and will report 

alarms and warning messages via the user display. Reference to these 
alarms and appropriate actions to be taken to rectify them can be 
found in 

Section 7 “Fault Finding”.
