Field Service Engineer ( Precision Cooling System)
Roles and Responsibilities
The Field Service Engineer is responsible 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 24/7operation 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.
