Cooling Towers Treatment – EST

Elgressy EST electrochemical systems are revolutionizing cooling tower treatment by providing a comprehensive and effective treatment against scaling, corrosion and bio-fouling.

Minimizing the risk of Legionella Pneumophila – LPB

Elgressy’ patented LPB system maximizes protection against Legionella Pneumophila bacteria in hot and cold water systems. The LPB system is effective, economical and safe.

Legionella bacteria are found in every possible water source,
with the best conditions for growth prevailing in hot water
systems.

Traditional treatment against Legionella is based on chlorine
dioxide dosing, which is dangerous, expensive and corrosive.

Corrosion prevention – ECP

Typically, hazardous chemicals are added to the cooling water to inhibit corrosion of system components, to retard mineral scaling and to limit bacteria growth.
