Up to 75% Smaller Technology Footprint

CSIDefender® does not require on-site chemical storage, and in almost every case, a single more powerful copper silver ionization controller is enough to handle higher daily water loads, reducing the technology capital cost and footprint compared to less powerful alternative CSI Legionella water treatment solutions.

Up to 66% More Cost-Effective than Alternative Legionella Water Treatment Solutions

CSIDefender® Legionella water treatment solutions help you reduce both capital and operational expenses. Reduce energy and labor costs compared to Thermal eradication or chemical treatments, and save money upfront by requiring fewer more powerful units compared to alternative, less powerful CSI solutions.
