YOUR FACILITY PLUMBINGHospital Legionella water treatment

healthcare Legionella water treatmentAccording to the EPA, potable water is the most important source of Legionella bacteria. In hospitals, where patients are already vulnerable to infections, the CDC has shown the risk of death from legionella rises to 25%. Highly publicized outbreaks have occurred in healthcare facilities in Michigan, Pennsylvania, and Virginia, among other locations across North America and the rest of the world, demonstrating the impact this deadly but preventable bacteria can have on public health.

Take a Proactive Approach to Legionella Growth Prevention & Compliance Requirements

Engineering Legionella Water TreatmentInstead of waiting for an outbreak, healthcare facilities can protect patients and reduce costs by taking a proactive approach that mitigates the risk of nosocomial infection before it occurs. Copper silver ionization in hospitals helps you comply with ASHRAE 188 Legionella Prevention Standards when secondary potable water treatment is recommended to prevent the growth and spread of bacteria through facility’s water distribution network.

Trust CSIDefender® for Safe, Reliable Legionella Growth Prevention

CSIDefender® is the trusted name in protecting facility potable water networks both for point of entry (POE) and domestic hot water (DHW) systems in healthcare facilities across North America and the rest of the world. Whether you’re upgrading an existing facility or at the design stage in a new one, CSIDefender® provides long term Legionella growth prevention and works across your entire water potable distribution system by saturating the biofilm with copper and silver ions to prevent existing or future Legionella growth issues.

Choose the solution that’s been relied upon for more than 20 years, has been engineered with leading edge expertise and materials, and is backed by a 10 year warranty. The CSIDefender® has a proven track record in preventing Legionella growth in hospitals and other healthcare facilities.

Benefits of CSIDefender®

Other treatment options, including Thermal-eradication and chemicals, cause wear and tear on infrastructure such as pipes, water faucets, valves and other components. Not only will this lead to more frequent maintenance and repairs, it also inadvertently creates new places for bacteria to grow and spread. Overtime, the damage can ultimately wipe out the cost savings and other benefits of prevention entirely.

By using positively charged copper and silver ions instead of harsh chemicals or high water temperatures, the CSIDefender® solution provides more effective water treatment without damaging critical water distribution infrastructure, reducing your maintenance costs and protecting your facility.

One of the most common hospital water treatment methods is to heat water to temperatures where legionella bacteria are killed, typically above 140°F. But this is known to increase energy costs and the associated risks of scalding vulnerable patients. Plus, thermal eradication isn’t a practical solution for warmer geographical areas where incoming water temperatures can be over 68°F (20°C), and where point-of-entry (POE) applications to treat all of the incoming water are required. Chemical treatment options on the other hand require either on-site storage or generators, ongoing service contracts and multiple applications, making them a resource intensive and expensive approach.

The CSIDefender® copper silver ionization prevention technology targets bacteria and prevents growth, while also saturating the biofilm with ions where legionella grows, preventing future unwanted bacterial blooms. The result is that CSIDefender® solutions are approximately 66% more cost effective and require less maintenance while providing measurably better results.

Whether you’re building a new facility or upgrading an existing one, CSIDefender® is easy to install and provides a much smaller technology footprint than other secondary water treatment solutions, with no need for on-site chemical storage. Based on a preliminary four step facility requirement assessment, we can easily guide you to determine the best Legionella growth prevention approach for your facility, including whether you should use a Point-of-Entry (POE) or Domestic Hot Water (DHW) type copper silver ionization solution. What’s more, facilities with multiple DHW zones returning to a common mechanical room (yet remaining separate at all times) can install more powerful “Multi-Zone” CSI technology solutions, making it one of the most cost-effective option for facilities with larger infrastructures.

Any time your legionella prevention system is not properly working is time that you are putting your patients at risk of potential infection. CSIDefender® works continuously and boasts an uptime of 99.99%, making it far more effective than alternative traditional methods such as thermal eradication or hyper-chlorination which normally only last for 3-6 weeks before Legionella CFU counts increase again. Engineered and made in North America from quality materials and components, the CSIDefender® is backed up with a 10 year warranty with minimal preventative maintenance requirements.
