Legionella bacteria causes Legionnaires’ disease, a severe and often lethal form of pneumonia. It can develop when a person comes in contact with water droplets contaminated with Legionella bacteria. Each year, an estimated 10,000 – 18,000 people are infected in the United States alone.

No, though commonly associated with cooling towers, a WHO report showed that cooling towers only accounted for 28% of cases. Other sources include water outlets, hot tubs, domestic plumbing systems, and other sources of potable water.

CSIDefender® Ion Chamber Cells contain medical grade electrodes which release positively charged copper and silver ions into the potable water distribution network. These ions bond with and neutralize Legionella bacteria, while saturating the biofilm where Legionella grows to prevent future growth. The result is a powerful and reliable solution that works across the entire water distribution system and keeps facility occupants safe from potential exposure.

Biofilm, normally made from organic living, organic dead and inorganic materials, builds up over time inside a facility potable water distribution network and nourishes Legionella bacteria, giving it a chance to grow and multiply. CSIDefender® releases positively charged copper and silver ions which saturates this biofilm in 30 – 45 days, creating an environment where Legionella can no longer grow and preventing the future growth of bacteria.

CSI technologies are completely safe for humans and do not pose a risk at EPA regulated potable water levels. Facility managers or building owners should regularly test the water for ions no less than once per week. Note that the EPA does not test or endorse commercial products, services, or enterprises.

Depending on the size of the unit and number of cells, it can take between 5 – 40 minutes to fully saturate and maintain ionic concentrations in your potable water distribution network. Ongoing testing should be conducted no less than once per week.

Yes, unlike PVC and CPVC, the industry leading CSIDefender® Ion Chamber Cells are housed in a cut grooved Schedule 40 (316) stainless steel jacket. Not only does this provide increased durability, it also exceeds local fire building codes and plumbing water pressure and temperature codes.

When properly sized and with regular preventative maintenance, a CSIDefender® Chamber Cell will last 12 to 18 months or longer.

Cleaning the chamber cells is required every 3-6 weeks depending on water conditions. To clean the unit, close the bypass, drain the chamber cell, clean, scrub, rinse and reinstall. This regular preventative maintenance can be done in less than 20 minutes. Cells should be replaced every 12-18 months, depending on the water load and electrode depletion, to maintain performance.

Failure to conduct preventative maintenance could damage the cell. The system will detect the lack of maintenance and trigger fault alarms, eventually shutting down automatically until the cell is properly cleaned.

All CSIDefender® components are manufactured in North America, and final construction is completed in Canada.

No, these units are not designed for facility potable water with large water volumes. Typically, they are smaller, do not adapt to varying water conditions, and have small electrons, meaning they do not provide the performance or durability required for larger water systems.

To determine whether you need a Point-of-Entry (POE) or Domestic Hot Water (DHW) application, answer the following questions:

  • Is your incoming facility water above 68°F?
  • Does your facility have low occupancy or the potential for water stagnation?
  • Are you geographically South (Southern USA, Central & South America, Southern Europe, Middle East, Asia)?

If the answer to any of these questions is yes, a POE application is required. If the answer to all is no, a DHW application should be sufficient unless otherwise recommended by an industry professional.

To size a copper silver ionization system for your domestic hot water zones, you need to know the following information:

  • How many DHW zones does your facility have?
  • If multiple zones, are they located in a common mechanical room?
  • What is the DHW load per zone?
    • How many beds/rooms are in each zone?
