Dental drill keeps constant pressure
A three-chambered design is ensuring a continuous flow of water under pressure to dental drills, while avoiding backflow should the mains pressure drop
.
Fears of contaminated water from dental treatment getting back into the mains supply have meant most surgeries rely on a bottle system – in which the bottles have to be constantly filled and emptied, and the water supply to the tools closely monitored.
The new system, developed by Norgren, is called Cerberus after the legendary creature that guarded the entrance to the underworld in Greek mythology. The upper of the three chambers is filled by water that falls through an air gap, conforming to the requirements of BS EN1717. Below this are two pressurised chambers that supply the water for the equipment. While one is supplying water under pressure, the other is being filled from the upper chamber. The system, which is fully automatic, takes advantage of the company’s solenoid valve and control technologies.
