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.
Required Skills & Competencies
Technical Skills

• Strong expertise in Chiller systems (air‑cooled, water‑cooled, centrifugal, screw, scroll).
• Knowledge of refrigeration cycle, psychrometrics, and HVAC electrical circuits.
• Experience with BMS/PLC-based chiller plant controls.
• Hands-on skills with pumps, valves, cooling towers, heat exchangers, and hydronic balancing.
• Troubleshooting capabilities for VFDs, control panels, and automation systems.
Soft Skills

• Strong analytical and troubleshooting skills.
• Customer service orientation.
• Good communication and teamwork.
• Ability to work in high-pressure, onsite environments.
Qualifications

• Diploma in Mechanical, Electrical, HVAC, or Refrigeration.
• 3–7 years of experience specifically with Chiller servicing (depending on role level).
• Certification in HVAC/R, chiller servicing, or related specialization (preferred).
• Knowledge of safety protocols, pressure vessel standards, and refrigerant regulations.
Work Conditions

• On-site field role (commercial buildings, manufacturing units, data centers, hospitals, malls, etc.).
• Requires physical mobility, lifting, confined space access, and working at heights.
• May involve rotational shifts or emergency service calls.
