Controlled Release

Smart Shield® Controlled Release System is designed for smaller systems and those with lower inhibitor chemistry demand. It uses controlled release chemistry to provide uniform treatment over a 30 day period of wet operation. Whenever the system’s condenser pump is in operation, recirculated water flows through the feeders coming in contact with the solid, polymer coated, chemistry, and then treated water is returned to the pump suction. This ensures consistent treatment whenever the cooling equipment is operating.

Monitored Release

Smart Shield® Monitored Release System is designed for larger systems and those with higher inhibitor chemistry demand.  It uses an advanced inhibitor probe to automatically monitor and maintain precise inhibitor residual throughout the evaporative cooling water application.  The solid chemistry for the Monitored Release Feeder is manufactured with an inert tracer dye which the advanced inhibitor probe can detect through the use of fluorescent light.  Using the controller that is included with the package, the Monitored Release System automatically determines the amount of chemistry in the condenser water and ensures continually precise control, even as the system’s thermal load fluctuates, as depicted by the graph above.
