IIAR Certificate Program

IIAR 2  Course Syllabus


Module 1 - General
This module will review the introductory content of ANSI/IIAR 2-2014.  This content includes the standard's purpose, scope and applicability for the safe design of closed-circuit ammonia refrigeration systems along with key definitions not yet adopted into ANSI/IIAR 1-2012 Definitions and Terminology Used in IIAR Standards. It addresses recognized standards from other organizations.  Presenter:  Trevor Hegg,  Director of Product Development at EVAPCO, Inc., (Taneytown, MD)

Module 2 - Part 1 - Design and Installation Considerations Affecting Construction
The second Training Module to the ANSI/IIAR 2-2014 Certificate Program is the first of two presentations covering the design and installation considerations affecting construction. This first part dives into the general system design requirements for closed-circuit ammonia refrigeration systems and the location of ammonia refrigeration machinery through examination of the normative text covered in Chapters 4 and 5 as well as the explanatory material presented in Appendix A. Presenter: David Blackhurst, Director, Star Technical Solutions (Glasgow, Scotland)

Module 3 - Part 2 - Design and Installation Considerations Affecting Construction
The third Training Module to the ANSI/IIAR 2-2014 Certificate Program is a continuation of the second training module covering the design and installation considerations affecting construction. What could be identified as the most important information in IIAR 2, this second part thoroughly investigates the requirements for machinery rooms. Additionally, the presentation begins to introduce information concerning refrigeration equipment located in areas other than machinery rooms which is a growing trend in the ammonia refrigeration industry through the introduction of packaged refrigeration systems. Presenter: Mark Stencel, Director of Business Development, Bassett Mechanical (Kaukauna, WI)

Module 4 - Part 1 - Equipment
The fourth Training Module to the ANSI/IIAR 2-2014 Certificate Program is the first of three presentations looking into specifics of ammonia refrigeration equipment. This first part dives into the requirements for the various types of compressors, refrigerant pumps and condensers that are presented in Chapters 8, 9 and 10. Presenters: Trevor Hegg, Vice President of Industrial Refrigeration Product Development, EVAPCO, Inc. (Taneytown, MD) and Joe Pillis, PE, Director of Global Industrial Refrigeration Techonology, Johnson Controls/Frick (Waynesboro, PA)

Module 5 - Part 2 - Equipment
The second of three presentations on ammonia refrigeration equipment, the fifth Training Module to the ANSI/IIAR2-2014 Certificate Program dives into the requirements for evaporators, pressure vessels and piping that are covered in Chapters 11, 12 and 13. Presenter: Bruce Nelson, President, Colmac Coil Manufacturing (Colville, WA)

Module 6 - Part 3 - Equipment
The sixth Training Module to the ANSI/IIAR 2-2014 Certificate Program concludes the three-part series on ammonia refrigeration equipment educating the participant on the specific requirements for packaged system, overpressure protection devices, instrumentation and controls and ammonia detection and alarms. This presentation covers the information in Chapters 14, 15, 16 and 17. Presenter: Peter Jordan, Senior Principal Engineer, MBD Risk Management Services (Langhorne, PA)

Module 7 - Part 1 - Appendices

While the information is only informative, the seventh Training Module to the ANSI/IIAR2-2014 Certificate Program provides the participant with valuable insight and interpretation into the normative text covered in the main body of the standard by reviewing the significantly expanded content of the appendices. This is especially true with respect to the new format of Appendix A. In addition to the explanatory material in appendix A, this module reviews the characteristics and properties of ammonia, methods for calculating relief valve capacity for heat exchanger internal loads, pressure vessel duplicate nameplating, method for calculating discharge capacity of a positive displacement compressor pressure relief device, pipe hanger spacing, hanger rod sizing and loading, and hydrostatic overpressure relief. Presenter: Don Faust, Vice President, Gartner Refrigeration (Minneapolis, MN)

Module 8 - Part 2 - Appendices

The last of the Training Modules to the ANSI/IIAR2-2014 Certificate Program presents the informative information in the remaining appendices including stress corrosion cracking, emergency pressure control systems, machine room signs, alternative ventilation calculation methods, pipe, fittings, flanges, bolting and operational containment. Presenter: Dave Schaefer, Chief Engineer, Bassett Mechanical (Kaukauna, WI)

Final Certificate Examination

How It Works
The IIAR 2 Certificate course includes eight training sessions, each approximately 60 minutes long, delivered as a PowerPoint presentation with lecture. At the end of each module, there will be questions to check comprehension of the material.  After comprehension of material is demonstrated, you can move onto the next module. To receive a certificate, participants will be required to pass a comprehensive final course examination.

Course Requisites
We recommend these minimum requirements for individuals interested in participating in this program:
* General knowledge of the physical properties of ammonia
* Familiarity with design and installation considerations affecting construction of closed-circuit ammonia refrigeration systems
* Working knowledge regarding equipment that may be employed in operational closed-circuit ammonia refrigeration systems

Learning Objectives
After completing this program, learners will be able to:
* Describe appropriate and safe location of ammonia refrigeration equipment and outline general design requirements for construction of closed-circuit ammonia refrigeration systems
* Discuss design and installation considerations for machinery rooms and requirements for refrigeration equipment located in areas other than machinery rooms
* Understand safe installation and proper operation of equipment that may be employed in closed-circuit ammonia refrigeration systems including: compressors, refrigerant pumps, condensers, evaporators, pressure vessels, piping, packaged systems and equipment, overpressure protection devices, instrumentation and controls, and ammonia detectors and alarms.


The IIAR Academy of Natural Refrigerants is a long-term education program created to address the need for competent professionals in natural refrigeration system design, safety and maintenance. The objective of the academy is to address the technical training needs of end users, design build contractors, equipment manufacturers and consulting engineering sectors of the IIAR membership. As industry codes and regulations change and evolve the need for competent professionals in our industry will continue to grow.   

IIAR Certificate Courses are based on ASTM standards and allow design engineers, installers and responsible parties to show that they have received documented and standardized instruction regarding design and operation of ammonia-based refrigeration systems, and/or the current regulatory environment within the industry.
