Project Overview

ChillChain Logistics specializes in temperature-controlled transportation for pharmaceuticals, vaccines, and perishable foods. Operating 200+ refrigerated vehicles and 15 cold storage facilities, the company faced compliance risks: poor temperature monitoring, manual documentation, lack of real-time visibility, and frequent spoilage incidents costing ₹50L+ annually.

GridMatrix deployed an end-to-end cold chain visibility platform combining IoT temperature sensors, real-time alerts, blockchain-based immutable records, and predictive analytics — achieving 99.4% compliance and reducing spoilage by 89%.

Challenges
  • Manual temperature logging via paper records and spreadsheets
  • Lack of real-time visibility into shipment conditions
  • Frequent temperature excursions causing product spoilage (₹50L+ annually)
  • Regulatory compliance risks (FDA, WHO guidelines not consistently met)
  • No auditable records for regulatory inspections
  • Difficulty tracing spoilage incidents to root causes
Strategy
  • Deploy IoT temperature/humidity sensors in all vehicles and facilities
  • Build real-time monitoring dashboard with automated alerts
  • Implement blockchain for immutable cold chain records
  • Create predictive models to prevent temperature excursions
  • Generate regulatory compliance reports automatically
  • Enable end-to-end supply chain visibility for stakeholders

Actions Taken

IoT Sensor Network Deployment
  • Installed 250+ multi-sensor IoT devices in vehicles and cold storage facilities
  • Deployed temperature, humidity, location (GPS), and door-open sensors
  • Configured real-time data transmission via cellular + backup satellite connectivity
  • Set up automated alerts for temperature thresholds and geofence violations
Blockchain-Based Cold Chain Records
  • Implemented Hyperledger Fabric for immutable cold chain transaction records
  • Recorded temperature checkpoints, handling events, and custody transfers
  • Enabled FDA 21 CFR Part 11 compliant digital signatures
  • Created tamper-proof audit trail for regulatory inspections
Real-Time Monitoring & Predictive Analytics
  • Built cloud-based dashboard with live temperature/location tracking
  • Deployed ML models predicting temperature excursions 30+ minutes in advance
  • Automated corrective actions (route rerouting, facility alerts)
  • Generated regulatory compliance reports (WHO, FDA guidelines)

Technical Implementation

The system combines industrial-grade temperature sensors (±0.1°C accuracy) deployed in 200+ vehicles and 15 facilities. Data streams to cloud via cellular/satellite with redundancy. A Node.js backend processes real-time data, triggers alerts via SMS/email, and logs transactions to a Hyperledger Fabric blockchain for immutability. Machine learning models (LSTM neural networks) trained on 2+ years of cold chain data predict temperature excursions with 94% accuracy. The dashboard built on React provides real-time KPI visualization, historical analytics, and compliance reporting. Integration with shipping management systems enables automated route optimization based on predicted temperature risks. All data is encrypted end-to-end and stored in India-compliant data centers.

Final Outcome

ChillChain Logistics achieved 99.4% temperature compliance and reduced annual spoilage losses from ₹50L to ₹5.5L (89% reduction). The blockchain-based immutable records enabled perfect regulatory compliance — passing 100% of audits with zero findings. Customer confidence improved, leading to ₹5Cr+ in new pharmaceutical contracts. The company now offers cold chain visibility as a premium service to customers, creating a new revenue stream. By preventing spoilage and ensuring regulatory compliance, ChillChain has positioned itself as the most trusted cold chain logistics operator in India.
