IIAR’s committees are essential to advancing the safe, efficient, and sustainable use of natural refrigerants. Comprised of volunteers from across the natural refrigeration community, these committees bring together the collective expertise of industry professionals to develop best practices, inform advocacy efforts, guide research, update technical standards, and expand education and outreach. Through their work, IIAR committees help shape the future of the industry, support informed decision-making, and ensure that the natural refrigeration community remains at the forefront of innovation and safety.
CO2 Handbook Committee
Developed and maintains the IIAR CO2 handbook, which guides refrigeration practitioners on the theory,
design, and practical application of refrigeration and heat pump systems that use carbon dioxide (CO2)
as the refrigerant. The handbook addresses subcritical CO2 application, transcritical CO2 applications,
and CO2/ammonia cascade system designs. The CO2 handbook committee may also develop research proposals
and educational program proposals related to the use and application of CO2 refrigeration and heat pump systems.
Compliance Guidelines Committee
Manages and updates the IIAR regulatory publications. The committee will maintain the PSM/RMP Manual,
ARM Manual, Ammonia Data Book and new regulatory publications.
Education Committee
Further the knowledge of the ammonia refrigeration industry and other parties affected by our industry through
the publication and dissemination of relevant industry information in the form of bulletins (an interpretation
of national codes and design methodology), videos, handouts, formal classes, workshops and seminars.
Energy Sustainability Committee
The Energy Sustainability Committee will be encompassing of not only the technical aspects but also the human
factors, social responsibility, and regulatory. In other words, we will need a large swath of skills and
expertise as we lay the foundation for tomorrow.
Government Relations Committee
Dedicated to government relations, the Government Relations Committee was formed to work directly with the
Institute’s government affairs representative. As IIAR continues to work on behalf of the industry with
government officials both in the U.S. and in other countries, the committee addresses issues important to
IIAR members and continues the organization’s tradition of advocacy on behalf of the industry.
International Committee
Expand IIAR activities around the world, recruit new members, translate IIAR publications and increase global
distribution of IIAR publications through appropriate refrigeration organizations worldwide.
Marketing Committee
Promote the use of ammonia refrigeration, reinforce IIAR's image within the ammonia refrigeration and related
industries through advertisements and advertorials in industry publications; ensure that industry information
is disseminated to members, industry and the general public; work with the headquarters staff on maintaining
the marketing plan; develop and administer effective programs to ensure continued growth of IIAR.
Piping Committee
Develop and publish consensus specifications for pipe fittings and pipe materials used in the construction of
ammonia refrigeration piping systems. Review other areas of interest that concern piping systems such as
cleanliness, welding procedures, insulation and pipe sizing and recommend appropriate response to review
issues which may include issuing publications.
Research Committee
Identify and develop work statements that when implemented will benefit the ammonia refrigeration industry,
and assist the IIAR staff in the development of these work statements into completed research projects.
Responsible Refrigerants Committee
The RRC monitors the rapidly evolving landscape of global refrigerant policy to safeguard member compliance. By fostering clear, consistent communication across IIAR membership, the committee translates complex regulatory changes, both future and current, into actionable insights with the intent of driving the industry transition to natural refrigerants.
Safety Committee
Develop and implement projects intended to inform as well as educate the ammonia refrigeration industry and
related parties on the proper and safe use of ammonia as a refrigerant and the proper and safe operation and
maintenance of ammonia refrigeration systems.
Standards Committee
Update and interpret the IIAR standard(s), review and interface with other standard writing organizations that
include ammonia and ammonia refrigeration systems within their standards, develop ideas for and write new
standards (and other publications of interest to the industry) to be sponsored by IIAR and work with the
American National Standard Institute (ANSI) and IIAR staff in moving standards through the ANSI approval/review
process.
