Eradication of Bacteria
Elgressy’s LPB system facilitates the automatic control and eradication of microorganisms, including Legionella Pneumophila bacteria, in hot water systems.
The system is based on an electrochemical process, which reduces significantly the buildup of sediment and scale within hot water systems.
Prevention of scale buildup and precipitation assists in the prevention of LP bacteria growth and also corrosion.
The system is chemical free and therefore prevents damage to system components, is not a health risk and is environmentally safe.
The Elgressy LPB system is patented in Israel and patent pending in the United States.
Tested and approved by the Spanish and Israeli Ministry of Health
The benefits of the Elgressy LPB system
Removes harmful bacteria and health dangers
By facilitating the efficient eradication of the potentially lethal LP bacteria, the LPB system provides a safer and healthier environment.
Chemically free water treatment
No chemicals are used in the process so that the water remains clean and healthy and poses no threat to people or the environment.
Prevents LP bacteria re-growth
Reducing scale build up and sediment, the system removes the LP bacteria’s favorite breeding ground and ensures a bacteria free water supply.
Efficient operation and a longer system life
Because the system uses no chemicals, operation is more efficient, vital components aren’t damaged and the systems life expectancy is significantly increased.
Lower operating costs
Operating costs are significantly reduced because less maintenance is needed, no expensive and harmful chemicals are used and water efficiency is greatly increased.
L.P.B – The Electrochemical Process
The Elgressy LPB system destroys buildups of the LP
bacteria, and prevents its reestablishment in hot water
subsystems by using an electrochemical process.
Three Step Process:
> Removal of Legionella Pneumophila bacteria
growth media
At the bottom of any hot water tank, there exists
the perfect environment for the development of LP
bacteria - sediment buildup. The LPB system prevents
the buildup of sediment by causing turbulence at the
water entry point thus preventing sediment and scale
buildup and depriving the bacteria of their
growth medium.
> Electrochemical disinfection treatment
Inside the reaction tank are unique titanium and nickel
oxide anodes, patented by Elgressy Engineering. With
a life expectancy of several years, these anodes do not
cause corrosion or water contamination. When direct
electric current is passed through the anodes a tiny
and controlled amount of free chlorine (CL2) is
produced along with oxygen radicals. Together they
help disinfect the water. Additionally, the pH levels of
the water are raised to 14, especially near the walls of
the tank. Such high pH levels prevent the development
of micro-organisms.
> High temperature treatment
As an additional safeguard, once the water has
undergone treatment in the LPB system, it is pumped
through heat exchangers where temperatures
exceeding over 70O C are attainable that destroy
any remaining bacteria.
