  • Key Responsibilities
  • 1. Execute planned preventive maintenance (PPM) schedules for all refrigeration systems, including tropical rooms, chilled rooms, and frozen rooms.
  • 2. Monitor and maintain optimal temperature parameters across all cold chain zones in strict accordance with defined Standard Operating Procedures (SOPs).
  • 3. Conduct routine inspections of compressors, condensers, evaporators, expansion valves, and refrigerant piping systems.
  • 4. Ensure refrigerant levels are maintained within specified limits and perform periodic leak detection tests.
  • 5. Monitor and maintain defrost cycles, drain lines, and insulation integrity of all cold rooms.
  • 6. Coordinate with Original Equipment Manufacturers (OEMs) and third-party service providers for specialized repairs and annual maintenance contracts.
  • 7. Diagnose and resolve refrigeration system faults, including compressor failures, refrigerant leaks, thermostat malfunctions, and evaporator icing.
  • 8. Respond to temperature excursion alarms and execute corrective actions within defined response timelines.
  • 9. Troubleshoot electrical and control system faults in refrigeration panels, PLCs, and Building Management System (BMS) interfaces.
  • 10. Perform root cause identification for recurring equipment failures and implements verified permanent fixes.
  • 11. Maintain and monitor Diesel Generator (DG) sets, including fuel systems, coolant levels, battery health, and periodic load bank testing.
  • 12. Execute preventive and predictive maintenance on Uninterruptible Power Supply (UPS) systems, including battery health checks, load testing, and firmware updates.
  • 13. Monitor and maintain electrical panels — including Main Distribution Boards (MDB), Sub-Distribution Boards (SDB), Automatic Transfer Switches (ATS), and change-over panels.
  • 14. Conduct periodic insulation resistance (IR) testing, earth resistance testing, and thermography surveys of all electrical systems.
  • 15. Ensure full compliance with applicable electrical safety standards and statutory requirements.
  • 16. Monitor real-time equipment parameters through the BMS, temperature monitoring systems, and energy meters.
  • 17. Conduct daily walkthroughs to identify abnormalities, unusual sounds, vibrations, or visual defects in equipment.
  • 18. Track and maintain equipment runtime hours, energy consumption data, and performance trends.
  • 19. Ensure all monitoring sensors and alarm systems are calibrated and fully functional at all times.
  • 20. Daily Reports — Prepare and submit daily equipment status reports covering temperature logs, DG runtime, UPS status, and all observed anomalies.
  • 21. Weekly Reports — Compile weekly maintenance summary reports covering PPM compliance, breakdown analysis, spare parts consumption, and pending work orders.
  • 22. Monthly Reports — Develop monthly performance reports inclusive of equipment uptime percentage, Mean Time Between Failures (MTBF), Mean Time To Repair (MTTR), energy consumption trends, and cost analysis.
  • 23. Conduct structured Root Cause Analysis (RCA) for all equipment breakdowns, temperature excursions, and safety incidents using methodologies such as Five-Why Analysis and Fishbone Diagrams.
  • 24. Develop and implement Corrective and Preventive Actions (CAPA) with clearly defined timelines, responsible owners, and effectiveness verification criteria.
  • 25. Maintain a CAPA tracker with closure status, evidence of implementation, and effectiveness validation records.
  • 26. Present RCA and CAPA findings during Weekly Business Reviews (WBR) and Monthly Business Reviews (MBR).
