CTR Pass

CTR PASS is a highly concentrated product specially developed for the passivation of galvanized steel in cooling towers. It contains several corrosion inhibitors as well as scale and hardness deposit control agents. It also incorporates tracers that allow easy monitoring of dosage and scale-control effectiveness. Thanks to its tagged polymer technology and PTSA tracer, its activity and performance can be continuously monitored directly in the water. In addition, its mild acidity helps reduce the Langelier Index during normal operating conditions.
