Protecting your domestic hot water system from Legionella and other pathogen contamination has never been easier. CSI Defender eliminates Legionella, maintaining the highest level of safety in your building
Legionella is prevalent in our water and soil. When it enters the piping system in a building, it embeds itself and grows colonies within Biofilm. The Biofilm provides a food source and protection from chlorine and heat shock attempts. Legionella growth is most advanced at temperatures between 25-42 C (77-108 F), right where many facilities run their hot water.
Legionella is a health risk when it becomes aerosolized and we breath it in. It can then infect our respiratory tract and presents as severe pneumonia, often with deadly consequences. The risk presents anywhere water sprays - cooling towers, misters, humidifiers, showers, medical equipment, etc.
There are a number of factors that increase the risk or presence of Legionella such as construction and water main breaks, changes in water quality, biofilm, scale and sediment, temperature or pressure fluctuations among others.
Copper Silver Ionization works by utilizing the antibacterial properties of copper and silver, and by using Legionella's safe haven against it. The installed chamber cell(s) are designed with silver and copper anodes which will slowly release silver and copper ions into the domestic hot water system, typically directly into the recirculation loop.
The silver and copper ions serve two important functions: 1) directly kill Legionella bacteria and 2) penetrate the Biofilm layer so that newly present Legionella brought in from the municipal supply is exposed to the silver and copper directly from the Bioflim.
The intelligent PLC control on the CSI Defender system will activate the chamber cells on a cycled schedule, typically overnight when little to no water is being used. The system is paused during the day when the water is being heavily used, preventing the Legionella killing ions from being flushed down the drain.
