Legionella prevention with Korn

The rise in illnesses caused by the bacteria Legionella pneumophila has recently been the subject of intense media attention.

This situation is addressed in the new VDI guideline, 2047-2, which offers guidance on the hygienic operation of chillers. Now, chiller operators are faced with the challenge of finding a sustainable solution for this problem.

ELBOLIT®: Efficient disinfection for technical water cycles

KORN service professionals were among the first participants to attend seminars on VDI 2047-2 and have also received professional training in the collection of samples from our partner for Legionnaires’ disease analysis, TRIWALA GmbH. Since VDI 2047-2 came into effect, the method it describes has become the recognized state of the art for chiller operation and open cooling circuits that employ evaporative cooling. Operators of such systems are responsible for adhering to the state of the art to avoid potential hazards. That includes comprehensive risk analysis and risk assessment in addition to seamless documentation of the system’s mode of operation in the operating log. KORN system technology solutions with web-enabled controllers and cooling tower control units automate this documentation.

Biocides from the ELBOLIT product line are very easy, fast, and efficient when used to combat Legionella pneumophila:

ELBOLIT® CL PLUS is a highly effective liquid disinfectant that generates a chlorine dioxide solution in situ. Thanks to its high concentration, even minimal dosing quantities are sufficient to produce enough chlorine dioxide to effectively treat technical water circuits. It has a strong germicidal effect, dissolves biofilms and prevents the formation of unpleasant odours.

Advantages and effects of ELBOLIT® CL PLUS 

• Innovative technology: based on a patented process, chlorine dioxide is provided safely and easily – without additional equipment or manual mixing processes. The solution is produced directly at the dosing point and takes effect in the cooling circuit.  
• Efficient oxidation potential: a high oxidation potential is generated in the circulating water. Reducing anions such as sulfite or nitrite are completely oxidised. Organic compounds are also converted into harmless oxygen derivatives and are therefore no longer available for chlorination (AOX formation).  
• Maximum biocidal effect: ELBOLIT® CL PLUS fights bacteria, yeasts, algae and viruses of all kinds. Its disinfecting effect is enhanced by additional chlorine oxide components, which prevents the formation of resistance.
• Algicidal properties: the broad-spectrum effect of chlorine dioxide is specifically effective against algae and prevents their spread in water circuits.

Summary of the advantages

• Highly efficient: effective even at low dosages.
• Versatile:: combats bacteria, viruses, yeasts and algae, prevents odours
• Safe: patented technology, no manual mixing required.

With ELBOLIT® CL PLUS you get a reliable solution for the disinfection and protection of your technical water systems. Ideal for applications where effective and sustainable water treatment is required.
