Epoxy barrier coating could stop Legionella

A recent Legionnaire’s disease outbreak in New York City has led to 86 people infected and 7 deaths, health officials said. After inspection it was determined that the bacteria causing the disease (Legionella) made their way into five cooling towers. Nu Line epoxy barrier coating technology (pictured above), is a solution for pipe systems that is manufactured in North America and provides protection against the transmission of diseases like legionella.


Nu Line is applicable for use in host pipes consisting of metal, iron, steel and concrete with diameters ranging from 1/2″ to 10 and above.

The Nu Line process sandblasts the pipe system to eliminate all debris and buildup in the pipe, which is a harbor for organisms such as legionella to multiply. Without fully removing the nebulas, the likelihood of biofilm forming and organisms returning is very likely.

After cleaning the system, the Nu Line then coats the entire pipe work with a barrier coating that does not allow for scale, tuberculation and consequently organisms to find a safe harboring for growth. Although all strains of the legionella bacteria can be killed easily and quickly within 3 minutes by exposure to temperatures of 70°C (158°F), the Nu Line process avoids the need to spike water temperatures to unsafe levels.

Nu Flow understands the responsibilities building owners and organizations have ensuring clean and safe pipe systems, which is why Nu Line epoxy barrier coating is a solution that should be considered in the fight against Legionnaire’s disease.
