Job description
The Ammonia Technician installs, starts up, and commissions OEM ammonia and natural refrigerant systems, ensuring they operate safely, efficiently, and in full alignment with design specifications. This role combines hands-on mechanical and electrical work with PLC-based control system integration, performance testing, and detailed documentation. The technician also provides onsite training to facility personnel and travels frequently to customer sites across the United States., * Perform detailed physical inspections and startup procedures for OEM refrigeration units, confirming that all mechanical and electrical components are installed correctly and safely.
- Conduct system startup activities, including verification of piping, welds, electrical connections, and overall system integrity prior to commissioning.
- Integrate and test PLC-based control systems by performing I/O checks and validating that all inputs and outputs function correctly.
- Verify that the control system operates according to the designed sequence of operations, making adjustments as needed to ensure proper system performance.
- Carry out performance testing, including pressure tests, vacuum pulls, and refrigerant charging on ammonia and other natural refrigerant systems.
- Diagnose and resolve complex mechanical, thermodynamic, and electrical issues that arise during initial system operation and commissioning.
- Troubleshoot PLCs and control loops, including identifying and correcting PID loop tuning issues to optimize system stability and performance.
- Read and interpret complex Piping and Instrumentation Diagrams (P&IDs) to verify system configuration and support troubleshooting activities.
- Perform field service work on ammonia refrigeration systems, including inspection, adjustment, and repair of system components as required.
- Support piping and welding-related tasks as they relate to system installation and commissioning, ensuring work meets quality and safety standards.
- Conduct onsite training sessions for facility managers and maintenance staff, explaining system operation, safety procedures, and basic troubleshooting techniques.
- Prepare and deliver detailed commissioning reports that include setpoints, sensor calibrations, test results, and any as-built deviations for the engineering team.
- Maintain accurate records of work performed, including tests conducted, issues identified, corrective actions taken, and parts used.
- Travel frequently to job sites across the United States, including ice arenas and other facilities, to install, start up, and commission chiller and refrigeration units.
