Woolworths Group operates one of Australia\u2019s largest grocery networks, with more than 1,200 stores<\/strong> relying on round-the-clock refrigeration to maintain food quality and reduce waste. One of the most disruptive challenges in-store operations faced was ice build-up<\/strong> in refrigerated display cases\u2014often triggering after-hours emergency callouts, risking stock loss, and overloading technician rosters.<\/p>

Through its long-standing partnership with Bueno, Woolworths shifted from reactive fixes to predictive prevention\u2014applying near real-time data and machine learning to forecast and resolve ice-ups before they became a problem.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ice-ups silently impair system performance, degrade food safety, and increase the risk of high-temperature alarms. At Woolworths, these events were historically treated as Priority 1 or 2 callouts<\/strong>\u2014requiring immediate response, typically after hours. Every event drove up costs, added strain to the workforce, and jeopardised stock.<\/p>

Across a network of 1,200 stores, the goal was clear: identify and eliminate the issue before it ever triggered a fault or alarm.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

To tackle this, Bueno deployed predictive analytics models<\/strong> across Woolworths\u2019 entire connected fleet. Drawing data from over 2 million points<\/strong> and analysing conditions every 5 minutes<\/strong>, the system tracks refrigerant flow, case temperatures, and defrost trends to detect early signs of icing<\/strong>.<\/p>

When Bueno\u2019s AI identifies a likely ice-up event, stores and technicians receive 5\u20137 days advance notice<\/strong>, enabling teams to schedule proactive service before the situation escalates.<\/p>
