Field Service Engineer ( Precision Cooling System)

Roles and Responsibilities

The Field Service Engineer is rresponsible for Installation, testing and commissioning, preventive maintenance, repair and troubleshooting of precision cooling units (CRAC/CRAH, in-row coolers, chillers, and close-control ACs) and to support 24/7 operation in mission-critical environments.

Key Responsibilities

1. Installation & Commissioning

• Supervise / execute site installation of precision cooling units per manufacturer specifications.

• Perform refrigerant charging, leak checks, piping, and electrical connections.

• Testing and Commission units with proper airflow, setpoints, humidity control, and alarm verification.

• Integrate with BMS (Building Management System) via Modbus, BACnet, or other protocols.

• Provide Operational raining to User.

2. Preventive Maintenance

• Execute scheduled Preventive Maintenance visits (monthly, quarterly / half-yearly) for critical cooling equipment contracted assets.

• Routine servicing to clean/replace filters, check fan belts/motors, inspect coils, condensate drains and humidifiers.

• Verify refrigerant levels, superheat/subcooling, and compressor performance.

• Inspect electrical panels, contactors, capacitors, and safety controls.

• Document all readings, logs, and component wear and submit service reports.

3. Corrective & Emergency Maintenance

• Respond to 24/7 emergency breakdown calls (SLA-driven, e.g., 2–4 hours response).

• Diagnose and fix faults: compressor failures, fan motor issues, controller errors, refrigerant leaks.

• Replace key components (compressors, TXVs, fan motors, PCBs).

• Use diagnostic tools (manifold gauges, multimeter, thermal imager, refrigerant leak detector).
