The Armstrong 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.

Applications: Automated system for optimizing cooling water based heat rejection processes used in: datacenters, ammonia compressors, automotive manufacturers, large circuit heat pump applications, condenser cooling, paint processes, injection molding, air compressors.

Performance range: Controls up to five cooling towers/fluid coolers and five Design Envelope pumps. No limitations in plant size and cooling capacity.
