Intro to Ammonia Refrigeration
Introduction to Ammonia Refrigeration is designed specifically in mind for people whom work around and or manage the ammonia refrigeration system. These prospective students don’t directly operate the system themselves. If so they should take Ammonia Operator 1. One does not have to be a 30 year vet to manage the system, but should know the basics with confidence and a general knowledge in industrial refrigeration . Key roles that that this class is designed for is plant management, supervisors, general safety, environmental safety, process safety, hazmat, and other key employee positions that have impact to the ammonia refrigeration system operations and maintenance tasks. We call this class
Intro to R-717 Refrigeration
No general background or prerequisites are needed to take this class. Aptitudes needed for for a better understanding will be mathematics, observation, applied technology, locating information, and reading for information. The class in a person is a 2 day session and online you have six months to complete.
The Intro to R-717 Refrigeration course entails a copy of the latest edition industrial ammonia refrigeration book hand selected by ARTS. This book is for the student to keep and reference not only during the class but their entire career. Topics to be covered are as follows:
