Installation and Commissioning

• Assist in the installation and commissioning of new refrigeration equipment and systems, ensuring proper setup, calibration, and testing.
• Connect power, water, and refrigerant lines according to schematics and safety standards.

Preventive and Corrective Maintenance

• Execute comprehensive preventive maintenance (PM) programs for all refrigeration units, including compressors, condensers, evaporators, cooling towers, pumps, fans, and associated controls.
• Perform routine inspections, cleaning, lubrication, and adjustment of refrigeration components.
• Monitor system performance parameters (e.g., temperatures, pressures, refrigerant levels, oil levels) and document readings.
• Conduct precise troubleshooting to diagnose mechanical, electrical, and control issues in refrigeration systems.
• Perform corrective repairs on faulty equipment, including component replacement (e.g., compressors, motors, valves, sensors, electrical boards).
• Recover, reclaim, and charge refrigerants (e.g., Ammonia, Freon) safely and in compliance with environmental regulations.
• Identify and repair refrigerant leaks using appropriate detection methods.

Plumbing and Drainage Works

• Maintain and repair water lines, drainage systems, condensate pumps, and plumbing fixtures related to refrigeration units.
• Ensure proper drainage to prevent water buildup, icing, or contamination in cold storage areas.
• Address plumbing-related service requests to avoid operational disruptions.

System Monitoring and Optimization

• Continuously monitor the performance of all refrigeration systems through Building Management Systems (BMS) or Supervisory Control and Data Acquisition (SCADA) systems, if applicable.
• Optimize system settings for energy efficiency while maintaining required temperatures and humidity levels.
• Analyze operational data to identify trends, potential issues, and areas for improvement.

Emergency Response

• Respond rapidly to refrigeration system alarms and breakdowns, including during off-hours, to minimize product spoilage and operational disruption.
• Execute emergency repair procedures safely and effectively.
• Be proficient in emergency protocols for refrigerant leaks, (e.g., wearing SCBA, emergency shut-down procedures).

Safety and Compliance

• Adhere strictly to all safety regulations, company policies, and industry best practices, particularly those related to handling refrigerants (Ammonia), electrical safety (LOTO), working at heights, and confined spaces.
• Ensure proper use and maintenance of Personal Protective Equipment (PPE), including specialized gear for refrigerant handling.
• Maintain accurate logs of refrigerant usage, recovery, and disposal in compliance with DENR regulations.
• Participate in safety drills and contribute to a strong safety culture.

Documentation and Reporting

• Accurately document all maintenance activities, repairs, refrigerant handling logs, and system readings.
• Prepare daily, weekly, and monthly maintenance reports, detailing completed tasks, outstanding issues, and spare parts consumption.
• Maintain organized records of equipment manuals, schematics, and service history.

Collaboration and Training

• Collaborate effectively with the Engineering Supervisor, General Services staff, and Operations team to coordinate maintenance activities and minimize impact on cold storage operations.
• Assist in training junior technicians or other staff on basic refrigeration awareness and safety.
• Provide technical input for spare parts procurement.

ELIGIBILITIES AND QUALIFICATIONS:

• Vocational or Technical Diploma/Certificate in Refrigeration and Air-conditioning Technology, HVAC, or Electrical/Mechanical Technology.
• Must possess a relevant government-issued license or certification for refrigeration system maintenance (e.g., TESDA National Certificate II (NC II) or higher in RAC Servicing).
• Certification in Refrigeration is a significant advantage
• Minimum of 3-5 years of hands-on experience as a Refrigeration Technician
