Navien Begins Shipping PeakFlow®C Commercial Scale Prevention Systems


Irvine, CA (August 18, 2022) – Navien, Inc., the leader in condensing technology, has started shipping the new PeakFlow C scale prevention system for commercial applications and larger homes. The PeakFlow C is the latest model in Navien’s line of eco-friendly scale prevention products which includes the PeakFlow S and PeakFlow A.

PeakFlow C is a chemical-free and environmentally friendly scale prevention system meant to handle flow rates up to 20 GPM, and can be installed either at the main water line to prevent scale for the entire water supply, or at the cold water inlet line just before a tankless water heater or combi-boiler DHW system.

“PeakFlow C is an outstanding addition to the Navien line of water quality products,” said Ernie Lee, Water Quality Product Manager at Navien. “The use of the PeakFlow C scale prevention system will help reduce unnecessary service hours due to scale issues for contractors working on larger domestic hot water applications.”

Navien PeakFlow technology transforms potential hard scale build-up to soft scale (aragonite and vaterite) that can easily be washed out with water flow. Without PeakFlow, the precipitated calcium carbonate forms as calcite, which is a very hard scale form that builds up in heat exchangers, lowering heat transfer efficiencies and blocking water flow.
