Design Envelope 9521 Integrated Tower Control System

The Integrated Tower Control 9521 is a simple and robust automation system for any cooling tower application, reducing its heat rejection load. The 9521 ITC works in a cooling tower heat rejection configuration and keeps the plant including cooling towers or fluid coolers and their fans, and Design Envelope pumps running smoothly.

Leveraging the flow readings from Design Envelope pumps, the system stability and tower automation are optimized for energy efficiency. The optimization is based on demand based control algorithms and Armstrong’s industry-leading Parallel Sensorless™ technology.
