Ammonia Operator 3 / Technician One
Ammonia Operator 3 / Technician One is for your lead ammonia operator and refrigeration supervisors. This class is developed for the understanding of ammonia engine room requirements and the complete maintenance aspects to them. This class is available in person and online. Each candidate for this class should have ammonia operator 1 & 2 credentials or the RETA CIRO certification. We call this certification
R-717 Operator 3 / Technician One
Most successful students have at least two years industrial ammonia refrigeration experience. Aptitudes needed for success are mathematics, observation, applied technology, locating information, and reading for information. The class in a person is a 4 day session. Candidates whom score well on ARTS certification test provided at the end of the course tend to do well on the RETA, TPC, and NUILPE certifications too. All ARTS certifications are active for a three window and carrier of those credentials must follow all company and regulator procedures.
The R-717 Operator 3 / Technician One course entails a copy of the latest edition industrial ammonia refrigeration RETA Book 3. This manual is for the student to keep and reference not only during the class but their entire career. Topics to be covered are as follows:
