Closed Loop Corrosion Inhibition: Review of Industry Trends, Technology Gaps, And the Next Generation in Closed Loop InhibitionClosed systems are found in a wide variety of applications, ranging from simple HVAC systems in residential buildings to increasingly complex manufacturing and heavy industrial production plants. This paper is broken down into 4 sections. First, traditional chemistries are reviewed including the most widely used mild steel corrosion inhibitors, molybdate and nitrite, with pros and cons fully discussed. The challenges of using borate compounds as
