Course Overview
As a refrigerant, ammonia has been in widespread use in the industrial sector for more than a century. With no ozone depletion potential and no global warming potential, it is environmentally friendly as well as an efficient choice for refrigeration. In this course, you will learn how to take advantage of ammonia’s desirable properties to design your refrigeration systems for peak performance. You will also learn from the experts about safety precautions and the latest research from the IRC that you can immediately apply on your next refrigeration system specification or design.
Who Should Attend?
- Design/build contractors
- Owners, plant operators, supervisors, engineers, and designers who want to better specify systems
- Project managers responsible for ammonia system design and construction
- Consulting engineers
Additional Information
This course is part of the Process Safety Management Professional Certificate. Increase your knowledge and effectiveness at managing PSM/RMP programs for your ammonia refrigerated facility, while earning a recognized credential. Course can be taken individually as well.
Beginning in the Fall of 2021, attendees participating in this course will be able to earn a digital badge as evidence of the knowledge they obtained during the course. Digital badges are micro-credentials that can be earned by successfully passing a final quiz administered online after completing the course. Find more information on digital badges.
