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). Required Qualifications & Competencies Education : ITE / Diploma in Mechanical or Electrical Engineering. Experience : 2-3 Experience in precision Cooling in CRAC / CRAH/ Chiller equipment. Technical skills : Refrigerants circuits diagnosis, electrical schematics, BMS Integration, VFDs and EC Fans. Soft skills : Customer-facing communication, structured reporting, remote support capability Others : Willing to work on-call 24/7 , Class 3 Driving licence travel to sites, and work in data centre environments Training : Training will be provided to enhance technical competency.
