Key Responsibilities

1. Chiller Installation & Commissioning

• Install, test, and commission water‑cooled and air‑cooled chillers, including screw, scroll, and centrifugal models.
• Configure and calibrate control panels, sensors, and safety devices.
• Conduct system performance checks including delta‑T measurement, flow rate verification, and pressure testing.

2. Chiller Maintenance & Repair

• Perform routine and preventive maintenance on chiller plant components such as:
  • Compressors
  • Heat exchangers (evaporator & condenser)
  • Cooling towers
  • Pumps, motors & VFDs
  • Expansion valves & refrigerant circuits
• Handle refrigerant charging, leak detection, and recovery per EPA/ASHRAE standards.
• Conduct chemical cleaning, descaling, and tube brushing of condenser & evaporator tubes.

3. Diagnostics & Troubleshooting

• Diagnose faults using advanced tools like:
  • Manifold gauges
  • Vibration analyzers
  • IR thermography
  • BMS/PLC control systems
• Resolve major issues such as chiller trips, high/low-pressure faults, oil circuit problems, and refrigerant imbalance.
• Interpret wiring diagrams, control schematics, and OEM manuals.

4. Chiller Plant Operations

• Monitor and optimize chiller plant parameters:
  • COP / kW‑TR
  • Water flow balance
  • Chilled water and condenser water temperatures
  • Energy efficiency
• Ensure integrated operation with AHUs, FCUs, and ventilation systems.

5. Documentation & Reporting

• Prepare detailed service reports, maintenance logs, and breakdown analysis.
• Maintain records of refrigerant usage, spares, and critical consumables.
• Provide recommendations for system upgrades and energy efficiency improvements.

6. Client Interaction

• Explain technical findings to clients and provide preventive maintenance guidance.
• Ensure professional behavior and maintain strong customer relationships.
• Train client teams on basic chiller system care and safe operation.
