A weeklong class using the RETA Course Curriculum providing the fundamentals of industrial refrigeration, up to simple troubleshooting and energy savings principals.

With a focus on various systems such as recirculated, flooded, direct expansion, cascade, vacuum cooling, and evolving package units using secondary coolants.

This course is not only for the entry level operator or manager with limited to no experience. It also provides additional troubleshooting and energy saving and compliance training for the chief engineer, experienced operator/technicians, environmental and safety personnel.

Fundamentals of refrigeration, refrigeration terminology, refrigeration system components (evaporators, condensers, compressors, valves, vessels, etc.) using RETA’s Industrial Refrigeration Study Course publications.

The practical goals of this course are to have each attendee leave with a sound understanding of their own plant’s system, reduce maintenance hours, extend the component life cycle, operate efficiently, trouble shoot and know what to do in an emergency.

Course ends with preparation for the entry level certification exam.
