The role is responsible for preventive and corrective maintenance, fault finding, equipment performance monitoring, breakdown response, energy efficiency improvement, and ensuring that utility equipment operates within required parameters. The role reports to the Maintenance. Controller

Key Duties & Responsibilities

• Carry out preventive and corrective maintenance on electrical equipment.
• Troubleshoot electrical faults on motors, MCCs, control panels, VSDs/VFDs, sensors and protection systems.
• Maintain electrical distribution systems, isolators, contactors, relays and control circuits.
• Diagnose motor starting and running problems.
• Attend electrical breakdowns and restore equipment safely and within agreed response times.
• Conduct electrical inspections and identify potential failure risks.
• Support installation, modification and commissioning of electrical equipment.
• Ensure electrical panels are clean, labelled and maintained to required standards.
• Conduct testing and verification after electrical maintenance.
• Support investigations into recurring electrical failures and implement permanent corrective actions.
• Operate, maintain and troubleshoot refrigeration and chilled-water systems.
• Maintain air-cooled and water-cooled chillers, compressors, pumps, cooling towers and associated equipment.

Troubleshooting

• Monitor refrigeration operating parameters and identify abnormal trends.
• Carry out preventive maintenance on refrigeration equipment.
• Check refrigerant circuits, filters, strainers, valves, sensors and control devices.
• Support refrigerant leak detection and repairs.
• Maintain chilled water circulation and ensure adequate flow to production users.
• Support cooling tower and condenser maintenance.
• Participate in refrigeration efficiency improvement projects.
• Execute the approved preventive-maintenance schedule.
• Complete maintenance tasks within planned timeframes.
• Record equipment condition and maintenance findings.
• Identify components approaching end-of-life.
• Recommend replacement of defective or unreliable components.
• Ensure critical spares are identified and communicated.
• Follow up on outstanding maintenance actions.
• Reduce repeat breakdowns through proper root-cause analysis.
• The technician should actively support reduction of utility consumption by:
• Monitoring compressor and chiller operating efficiency.
• Identifying unnecessary running equipment.
• Reducing no-load running of compressors.
• Monitoring refrigeration temperatures and pressures.
• Identifying abnormal energy consumption.
• Supporting energy-saving projects.
• Monitoring utility consumption against production volume.
• Reporting abnormal utility performance.
• Supporting reduction of kWh/1,000 L production and other site utility ratios.
• Comply with all plant safety requirements.
• Apply Lock-Out/Tag-Out (LOTO) before maintenance.
• Follow electrical safety procedures.
• Follow refrigeration and pressure-system safety requirements.
• Use appropriate PPE.
• Ensure equipment is isolated and proven dead before electrical work.
• Maintain good housekeeping.
• Report unsafe conditions immediately.
• Participate in safety inspections and toolbox talks.
• Never bypass safety interlocks without approved authorization.
