Digital Controls

Improving facility operations and chiller life with advanced digital controls

AZZ Nuclear has upgraded numerous old chillers to modern digital controls. Analog controls are very limited in what they can do, and older poor performing chillers frequently trip offline, which can result in reduced operating conditions and ultimately reactor scrams. Digital chillers can monitor more parameters and take certain actions to keep chillers operating at reduced capacity rather than simply tripping offline. Plants can often add 10 years to the life of an older chiller, which is in good mechanical condition, by simply replacing the controls.
