Dual Effect Heat Pump (DEHP) technology developed by Quantum LegioGuard sets new standards in legionella control with its patented process to heat and cool water simultaneously. This results in thermally sanitised hot and cold water supply to a facility in an energy efficient manner. Coupled with constant and accurate temperature control through the unique four port mixing valve, Quantum LegioGuard is the industry leader in safe, sanitised and reliable cold and warm water delivery.
Utilising Quantum LegioGuard’s DEHP technology, LegioGuard systems heat all incoming potable water to approximately 70˚C and simultaneously cool a portion of the 70˚C water to between 15-20˚C for supply to the facility. All the cold water for amenities passes through the heating process, thereby cold water in the facility is sanitised. LegioGuard systems mix the sanitised hot water and cold water with a large mixing valve (up to 380 litres per minute), distributing sanitised warm water.
