Inspection / Testing / Maintenance – ITM is one of our hottest classes to date. It is for any body with industrial refrigeration experience that wants to get a better grasp of mechanical integrity requirements to their system. This class is available in person and online. No prerequisite are required. We call this certification

ITM – Inspection / Testing / Maintenance for R-717 Systems

The Inspection / Testing / Maintenance for R-717 Systems course entails a copy of the latest edition industrial ammonia refrigeration manuals hand selected by ARTS. These manuals are for the student to keep and reference not only during the class but their entire career. Topics to be covered are as follows:
