- Install, service, maintain and repair industrial and commercial refrigeration systems.
- Maintain cold rooms, chillers, freezers, blast chillers and cooling units.
- Inspect refrigeration systems to identify faults, refrigerant leaks and mechanical failures.
- Monitor evaporators, condensers, compressors, expansion valves and refrigeration pipework.
- Conduct preventative maintenance to minimise equipment breakdowns and production interruptions.
- Ensure refrigeration systems maintain the required operating temperatures.
- Fault-Finding and Repairs
- Diagnose electrical, mechanical and refrigeration-related faults.
- Repair or replace defective compressors, motors, fans, thermostats, sensors and control components.
- Identify and repair refrigerant leaks in accordance with applicable regulations.
- Test refrigeration systems after repairs to confirm correct operation.
- Respond promptly to emergency breakdowns, particularly where meat storage or production is affected.
- Investigate recurring faults and recommend long-term corrective measures.
- Abattoir Cold Chain Management
- Ensure cold rooms, chillers and freezers maintain their specified temperature ranges.
- Monitor temperature readings and investigate deviations.
- Assist in maintaining the cold chain for meat processing, chilling, storage and dispatch.
- Identify refrigeration issues that could compromise product quality or food safety.
- Liaise with production, quality assurance and maintenance teams regarding refrigeration performance.
- Maintain accurate records of temperature checks, servicing, repairs and breakdowns.
- Electrical and Control Systems
- Inspect and troubleshoot refrigeration electrical circuits and control panels.
- Maintain thermostats, pressure switches, temperature sensors and electronic controllers.
- Test motors, contactors, relays and other electrical components within the technician's competency and authorisation.
- Identify faults in automatic defrost systems and refrigeration controls.
- Read and interpret electrical diagrams, wiring diagrams and refrigeration system schematics.
- Industrial Refrigeration Equipment
- Maintain industrial refrigeration plant and associated equipment, where applicable.
- Inspect compressors, pumps, cooling towers, condensers and evaporators.
- Monitor refrigerant pressures, temperatures and system performance.
- Check oil levels, filters, belts and other relevant components.
- Assist with energy-efficiency improvements and optimisation of refrigeration systems.
- Monitor equipment performance and report potential failures before they affect operations.
- Health, Safety and Environmental Compliance
- Follow occupational health and safety procedures when working with refrigeration equipment.
- Handle refrigerants safely and prevent unnecessary refrigerant emissions.
- Follow applicable refrigerant handling, recovery and environmental requirements.
- Use appropriate personal protective equipment.
- Follow lockout and isolation procedures when working on electrical or mechanical equipment.
- Maintain a clean, organised and safe maintenance workshop.
- Comply with the abattoir's hygiene, food safety and site access requirements.
- Administration and Reporting
- Complete maintenance job cards, service reports and breakdown reports.
- Maintain records of refrigerant usage, repairs and preventative maintenance.
- Monitor spare parts and refrigeration consumables.
- Report major equipment failures and replacement requirements to management.
- Assist with maintenance planning, contractor coordination and cost control.
