GCAP’s Advanced RETA Refresher Competencies
Prerequisite: Suggest GCAP’s prior Ammonia Operator 1 and/or Ammonia Operator 2 Credentials
This class is designed to be a refresher for any individual that is looking to attempt RETA Certification credentials such as the CIRO (Certified Industrial Refrigeration Operator). Individuals can also take this class as an overview refresher without sitting for the exams.
If a student wanted a review for the CARO exam we would suggest to take GCAP’s Ammonia Operator 1 Course as that is the best class for the review of material. GCAP’s Operator 2 is best suited to prepare some one for the CIRO exam. This course (ARR) is for individuals whom have have past experience, training and are now trying to sit for the certification and would like a review/refresher before taking the test. Also, many certifications/licenses across the country require continue education credits. This class can meet what most require.
We suggest that you bring you past Ammonia Operator 1 and 2 books and the course will be supplemented with the book “Seeing Industrial Refrigeration from the Inside Out”. The class will be studying from multiple sources to prepare for the optional certification(s). If you don’t have any prior books contact our office.
GCAP will provide several supplemental handouts, refresher exams, study questions, and RETA’s Online practice exam for the CARO/CIRO exams. Participants will have the option of sitting for the RETA CIRO Examination on the last day of class (must meet RETA requirements for testing and testing fees are separate). For RETA requirements and testing fees please contact our office.
