EST - The Electrochemical Scale Treatment System (E.S.T) is a state of the art patented system which prevents scaling prevents bio fouling microorganism growth inhibits corrosion produces oxidants in the water and prevents the spread of airborne bacteria. Using a unique electrochemical process the E.S.T system actively efficiently and cost effectively deals with the problems associated with cooling water systems without using harmful chemicals. LPB - 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. SCP - (Scale Crystallization Prevention) is an electrolytic system that prevents scale deposition reduces and removes chlorine and bacteria from the water and substantially reduces corrosion rates. The SCP is connected externally to the heat exchange unit and needs no complicated installation procedures or changes to your existing system. This in itself represents a significant saving in installation and maintenance costs.
