The dental unit must be a practical equipment in use, but
with the characteristics that allow the rapid and safe
application of the infection control practice, to reduce the
risk of infection.

For this reason, CEMM MEDICAL ITALY has specially
 engineered the S4/WD system for the disinfection of the
 dental unit waterlines. This system allows the users to
 control the biofilm that grows in the unit's waterlines.
The S4/WD water system has two pressurised reservoirs 
made in durable beverage PET: one for the disinfectant
and the other for the water-rinse at the end of the
cycle.


The biofilm that grows    in the unit waterline scan be prevented and reduced by the combined
action of 3 disinfection phases:

• Phase 1: Blowing of the disinfectant in the unit
 waterlines, to intervene on the surface biofilm both
 chemically and mechanically

• Phase 2: Permanence of disinfectant in the unit
 waterlines to permit a deep neutralisation action of
 the biofilm

• Phase 3:    Rinsing with air and water to remove the
disinfectant and reduce the surface biofilm
