Apply the Ammonia Refrigeration Standard in Your Facility

The pressurized ammonia in industrial refrigeration systems can pose serious hazards if workers can’t easily identify the system’s parts. To help, the International Institute of Ammonia Refrigeration (IIAR) created a standard for labeling ammonia pipes and related components. IIAR Bulletin No. 114 describes a color scheme, label format, sizing recommendations, and abbreviations for these pipe markers.

This full-color reference guide collects the essentials in one place. Get your free copy as a quick reference or training material, and use the IIAR approach to keep your ammonia refrigeration system running smoothly.
