ETL and CSA C22.2 Сompliant Copper-Silver Ionization System for Water Treatment Manufacturer

A proven method in need of a certifiable connected product

Our client manufactures copper-silver ionization systems for drinking water. The method is well established: electrodes release controlled amounts of copper and silver ions into the water supply, where they suppress bacteria such as Legionella in building plumbing.

The chemistry worked well. The challenge was the product around it. A system installed on a live drinking water line has to dose precisely, run unattended for months, and show operators what it is doing without someone walking up to every unit.

Market access raised the bar further. To sell in the US and Canada, the system needed an ETL listing and compliance with CSA C22.2 – electrical safety requirements that shape enclosure, insulation, wiring and power design from the first schematic. Discovering a gap at the test lab means redesign, re-testing and months of delay.

The client needed:

• Three hardware components designed to North American safety standards
• Firmware that runs the ionization process reliably on the device
• A cloud platform that gives operators remote visibility across installations
• One partner accountable for every layer – and for getting through certification

That’s when the company reached Yalantis to engineer the system end to end.

Hardware, firmware and cloud engineered as one system

Yalantis designed every layer of the product, from the electrode driver to the operator dashboard. Each decision was made with the full system in mind: how the hardware behaves on a live water line, how firmware keeps dosing accurate as conditions change, and how operators manage a growing fleet of installations.
