Protecting Cold-Chain Integrity for a National Food Distributor

Challenge

Maintaining product integrity during transit is essential, yet summer heat and aging delivery fleets often create
unnecessary operational stress. For this distributor, several variables made it difficult to guarantee the freshness of
produce, dairy, and meats during the final mile.

Operational Vulnerabilities:

• Lack of real-time data on refrigerated truck conditions.
• Relying on drivers for periodic temperature checks.
• Rapid temperature rises during frequent door-open events.
• Limited data to investigate losses or optimize routes.
• These challenges frequently led to inventory spoilage and customer concerns. By addressing these gaps, the
  distributor
  can move toward a more predictable, secure supply chain where food safety and inventory quality are consistently
  protected.

Solution

Plumsense implemented a comprehensive cold-chain monitoring system across 180 delivery trucks. This transition from
manual checks to automated oversight provides a reliable safeguard for temperature-sensitive cargo.

The Solution Framework:

• Continuous temperature and humidity monitoring ensures a stable environment for produce, dairy, and meats.
• Sensors monitor door-open events to manage and mitigate temperature spikes.
• GPS-enabled cloud reporting provides managers with instant visibility into every vehicle in the fleet.
• Predictive notifications trigger when temperatures cross 2°C or 5°C thresholds, allowing for immediate corrective action.
• By identifying refrigeration failures and high-risk route segments as they happen, the distributor can now maintain
  product quality and operational accountability with total confidence.

Results

88% reduction in monthly spoilage costs ($92,000 → $11,000) 71% decrease in customer complaints Annual inventory
write-offs reduced from $1.1M to under $200K Door-open violations reduced from 24 per day to 4 per day

Key Benefits

• End-to-end shipment traceability
• Predictive maintenance for refrigeration units
• Improved driver accountability
• Consistent compliance with HACCP and ISO food safety standards

Conclusion

Plumsense has shifted the distributor’s cold-chain monitoring from a reactive struggle to a predictive, streamlined
operation. By providing real-time visibility and actionable intelligence, the system ensures that every shipment arrives
in peak condition. This transition resulted in over $800,000 in annual savings, significantly strengthening the bottom
line while reducing losses and improving overall compliance. Following this proven success, the solution is being
expanded across all distribution hubs to standardize quality and ensure operational security nationwide.
