AI-Powered Freezer Health Score Case Study 

How a Simple Metric Could Save Your Science — and Hundreds of Thousands of Dollars

Why It Matters

• Health score learns each unit’s “normal” and flags drift early so teams can act before failure
• A Swedish university freezer failure destroyed decades of samples and prompted a national investigation¹
• 71% of lab professionals report experiencing a cold storage failure; fragmented data practices make prevention harder²
• At RPI, a silenced alarm led to 20+ years of research lost and a seven-figure lawsuit³

What’s Inside

• A team that acts on a yellow health score and averts a potential seven-figure loss vs one that ignores decline and incurs $120k in spoilage and delays
• Trend-based analytics combining environmental signals and usage behavior to surface subtle performance issues before thresholds trip
• Maintenance prioritization, escalation paths, and documentation to keep operations audit-ready
• Integrates with dashboards, alerting, and audit logs; informs criticality, PM planning, and procurement

Proof Points

• Early intervention based on health score prevents downtime and protects high-value materials
• Ignored decline led to immediate loss and schedule impact; early warnings resulted in uninterrupted operations
