Large-Capacity Troubleshooting (Must-Have)

• Hands-on diagnosis for large tonnage chillers/central plants (e.g., 200–1500 TR and above).
• Experience with centrifugal & screw compressors, oil management systems, purge units, condenser tube maintenance, and approach temperature optimization.
• Familiarity with water quality/chemical treatment basics and their impact on heat-exchange efficiency.

Qualifications & Requirements

• Diploma/Certificate in HVAC/Mechanical Technology or equivalent.
• 5+ years field experience in chiller/central plant service (industrial/commercial sites).
• Strong electrical/mechanical aptitude; can read schematics, P&IDs, isometrics.
• Competence with multimeters, manifolds, vacuum pumps, recovery units, and vibration/temperature data loggers.
• Knowledge of safety standards, LOTO, refrigerant handling, and environmental compliance.
• Basic IT skills for service software and report writing; valid driving license.
• GCC experience and Arabic/English communication are advantages.
