Copper-Silver Ionization Legionella Growth Prevention & Compliance Solutions for Domestic Hot Water (DHW) or Point of Entry (POE) Applications.

3rd party certified

Copper Silver Ionization Cells by CSIDefender® provide better performance through superior engineering design. 100% Made in North America, these industry leading CSI Chamber Cells include eight “Certified Pure” ionization electrodes. They also feature commercial grade electrical connectivity protection all housed in a cut grooved Schedule 40 (316) stainless steel external jacket.

Unlike PVC and CPVC, the stainless steel jacket meets all fire and plumbing building codes. It also provides superior tolerance levels in any liquid potable water temperatures or pressures. Combined with the industry leading CSIDefender® controllers, and with less that 3PSI drop in pressure, these robust military grade Copper Silver Ionization (CSI) chamber cells are the best engineered solutions on the market today.

Benefits of CSIDefender® Solutions


3rd Party Certified Pure High Quality Electrodes

Copper Silver Ionization Chamber Cells by CSIDefender® include 8 custom moulded medical grade copper-silver alloy electrodes (or separate pure copper and pure silver) mounted inside each ionization chamber in a cross configuration. Unique in the industry to provide double the electrode surface contact area and increasing efficiency and effectiveness. The electrodes work by releasing positively charged copper and silver ions into the potable water to saturate biofilm and prevent the growth of Legionella bacteria. Through this innovative design, the water flow capacity and total electrode surface area are unmatched by any traditional exposed-end electrode solution.


Industry Standard, Reliable and Easy to Use Cut Grooved Connection

Industry has made it very clear that the use of standard off the shelf couplings or flanges is preferable over proprietary type connections for ease of installation and access to parts. We listened and the CSIDefender® stainless steel ionization chamber cells feature cut grooves connections that use industry known Victaulic® or Di-Lock® unions (or flanges). This make installation and ongoing maintenance of the ion chamber cells easy and practical regardless of your geographical location


Fire and Plumbing Code Compliant

High quality schedule 40 stainless steel construction, industry known and reliable Victaulic® unions or flanges, and pressure tolerances well beyond 500PSI make the CSIDefender® solution durable, fire and plumbing code compliant, and easy to maintain.


Reduced Technology Footprint

When combined with CSIDefender® Controllers, users can significantly reduce their technology footprint without sacrificing on power and performance. Depending on your needs, you can connect multiple chamber cells to a single more powerful CSI controller. These more powerful CSIDefender “Multi-Cell” models (20 amps to 160 amps) will let you lower your technology footprint by up to 80% and relative capital installation cost by up to 46% without any performance compromise.


Legionella Growth Prevention Versatility in any Potable Water Conditions

Built with the highest quality, 100% American and Canadian materials, CSIDefender® Ion Chamber Cells are engineered to perform in any potable water conditions, temperatures, or pressures.
