The Annual IIAR Natural Refrigeration Conference and Expo is the largest exposition dedicated to the ammonia and natural refrigeration industry. We provide an unrivaled opportunity for the industry's leading manufacturers, contractors, trainers, and other service providers to showcase their latest innovations and products. With over 1,500 in attendance last year, this is a perfect chance to network and collaborate with some of the greatest minds in the natural refrigeration community. Our 2018 IIAR Conference and Heavy Equipment Expo was held in Colorado Springs, Colorado. With more exciting activities and programs added, the 2018 IIAR Natural Refrigeration Conference & Expo is one you won't want to miss.
