Organizational Overview

IIAR is an organization that serves those who use industrial refrigeration technology through education and advocacy. The Institute promotes the safe use of ammonia and other natural refrigerants through education, information, and standards. Our members include industrial refrigeration end users, many of whom are large multinational food processing companies, beverage producers and cold storage warehouse operators. Our membership also includes ammonia refrigeration contractors, engineers, component manufacturers, suppliers and academics. Each year, more than 1,000 ammonia refrigeration professionals representing all of our membership categories from around the world, attend the IIAR Industrial Refrigeration Conference & Exhibition. It’s the largest event dedicated exclusively to industrial refrigeration held anywhere in the world.

The IIAR Industrial Refrigeration Conference & Exhibition presents a balanced program of technical paper presentations, panel discussions, and forums. The sessions address cutting edge engineering, design and operational issues and topical subjects that affect the business in general, such as codes and standards, regulatory compliance, marketing and insurance issues.

IIAR is also a technical resource for the industry. Publications focus on regulatory compliance, training, system design standards, piping guidelines and operating and maintenance guidelines. The IIAR website,, also houses the largest industrial refrigeration on-line technical library containing more than 400 technical papers and publications that are available to IIAR members.

Scope of Standards Developing Activity

IIAR is currently the only organization writing performance standards for ammonia refrigeration systems. IIAR has two standards in publication, ANSI/IIAR 2-1999, Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems and ANSI/IIAR 3-2005, Ammonia Refrigeration Valves. We are also developing a new suite of standards, following ANSI guidance, covering Start-up and Commissioning, Maintenance and Inspection, Installation, Decommissioning and Developing Operating Procedures for Ammonia Refrigeration Systems. Our goal is to be the premier provider of performance standards for industrial refrigeration worldwide. IIAR also offers several guidance and training program documents for regulatory compliance, operator education and best engineering practices in the industry.

IIAR signed a Memorandum of Understanding with the Chinese Association of Refrigeration in 2007. The two organizations are enjoying a free flow of information and visitors to each others’ events. The IIAR standards are being adopted into the Chinese system by CAR. Representatives of IIAR make visits to China several times each year to nurture this valuable relationship. The organizations are working together to improve the use of industrial refrigeration in the food cold chain. Annual meeting technical presentations are simultaneously translated in Chinese.
