According to the CDC, 80 percent of legionella outbreaks in healthcare facilities were associated with long-term care facilities such as nursing homes. Water distribution systems and storage tanks leading to showers, sinks, bathtubs and medical equipment are all potential sources of bacteria growth.

CSIDefender® Copper Silver Ionization Legionella water treatment solutions generate clinically proven and field tested positively charged copper (Cu+²) and silver (Ag+) ions to prevent legionella bacteria growth and saturate the biofilm where it grows. This approach dramatically reduces the risk of nosocomial acquired infections associated with Legionella by vulnerable residents and provides a safer facility environment to all occupants.

Over 46 CSIDefender® different solutions to choose from to fit your Legionella control or prevention needs within your facility potable water distribution networks.

Copper Silver Ionization Legionella water treatment solutions for assisted living and nursing homes by CSIDefender® are easy to implement, reliable, and affordable solutions. They provide Legionella potable water prevention peace of mind for Nursing Home owners, occupants, employees, and visitors while helping comply with CMS Legionella Mandate Ref: S&C 17-30-Hospitals/CAHs/NHs.

Protect your residents from Legionella exposure and potential Legionnaires’ Disease with CSIDefender® Legionella water treatment solutions. The elderly population is at a far greater risk of contracting and succumbing to Legionella, meaning nursing homes and other residential care facilities, such as long-term care and assisted living, must effectively prevent the spread and growth of this bacteria. A proactive, affordable, and discreet approach that uses secondary water treatment, such as copper-silver ionization (CSI), is the only way to protect your patients fully. CSIDefender® can help you comply with ASHRAE 188 Legionella Prevention Standards when secondary facility water disinfection is recommended.

Copper Silver Ionization Benefits

Copper Silver Ionization Solutions
for Legionella Domestic Hot Water Treatment

copper silver ionization modelsCSIDefender® Coppersilver Ionization is a Legionella potable water treatment technology for Legionella growth control and prevention.

CSIDefender®, engineered for medical & commercial applications, are installed to provide Legionella potable water treatment in either domestic hot water distribution networks or point of entry applications

Legionella is a bacterium known to cause Legionnaires’ disease, a preventable form of severe pneumonia. Copper-silver ionization is commonly specified by consultant engineers for new construction projects and retrofits in existing facilities. C-ETL-UL, CSA, CE, and NSF/ANSI61 on all wetted components.

Copper-Silver Ionization Kills Legionella Across Entire Potable Water Distribution Networks

Thermal-eradication and hyper-chlorination chemical treatments can be useful in the short term, however legionella will typically reappear within 3-6 weeks after the process is complete. These treatment options are not considered long-term Legionella growth prevention solutions and do not thoroughly saturate existing biofilm, and other contaminants that harbor legionella growth.

CSIDefender® works by generating and releasing copper and silver ions into the potable water, providing automated computer control long term protection against bacteria growth without the need for periodical costly repeated short-term treatments. These ions fully penetrate the biofilm within 30-45 days, killing bacteria at the source and preventing future growth across the entire water system.

Both chlorine and thermal eradication are short term solutions that are resource and labor-intensive.

CSIDefender® copper-silver ionization solutions are up to 66% more cost-effective than these less reliable solutions.

Mitigate the risk of legionella growth, and the costs of an outbreak, with CSIDefender®.

Safe, Chemical Free Water Treatment

Some plumbing code regulations require that domestic hot water (DHW) systems deliver water at no more than 120°F, which also happens in the temperature range for legionella growth. One of the most common growth remediation techniques used by nursing homes is thermal-eradication, which uses superheated water at 140°F (or higher) to kill the bacteria. Those with experience understand that this approach is a massive waste of energy, increases the risk of scalding to the elderly residents, and is known to damage existing plumbing infrastructure features such as faucets and showers that are typically not designed for these higher water temperatures.

CSIDefender® works differently. By releasing positively charged copper and silver ions that bond with Legionella bacteria, they prevent the growth by saturating the biofilm where these bacteria are known to grow. No chemicals, No scalding hot water, and the technology delivers a safe, reliable, and effective alternative for long-term care and nursing home occupants.

Cost-Effective Legionella Solutions without Sacrificing on Performance

Prevent legionella while working within your capital and operational, budgetary constraints. Thermal-eradication techniques significantly increase energy costs, and chemical treatments that use chlorine or chlorine dioxide require costly third-party service contracts.

Both chlorine and thermal eradication are short term solutions that are resource and labor-intensive. Alternatively, the CSIDefender® copper-silver ionization solution is up to 66% more cost-effective than these less reliable solutions.
