The Ammonia Refrigeration Library is a full compendium of all IIAR standards for ammonia refrigeration and is a convenient way for industrial refrigeration professionals to purchase them at a discount. Note that IIAR members have access to electronic versions of all of the standards as part of their member benefits. The Ammonia Refrigeration Library contains the following IIAR standards: ANSI/IIAR 1-2022, ANSI/IIAR 202021, ANSI/IIAR 3-2022, ANSI/IIAR 4-2020, ANSI/IIAR 5-2019, ANSI/IIAR 6-2019, ANSI/IIAR 7-2019, ANSI/IIAR 8-2020, and ANSI/IIAR 9-2020, Addendum A 2024. Note that ANSI/IIAR standards are updated approximately every 5 years, with occasional addenda in within this period. Purchase of a hardcopy version of the library includes a special 3-ring binder for keeping the standards together.
