Did you know that there is an international association serving those who use ammonia refrigeration technology?  This association called IIAR, or International Institute for Ammonia Refrigeration,  is recognized throughout the industry and by governments around the world as the authoritative source of information about ammonia refrigeration.

The IIAR has developed a comprehensive ammonia labeling system, much like ASME has for other piping systems. This ammonia specific labeling scheme is outlined in the IIAR Bulletin No.114. This bulletin suggests recommendations on pipe marker label sizes, marker colors, pipe marker installation locations and pipe label material requirements.

There are a variety of ammonia pipe markers available to accommodate your ammonia refrigeration pipe marking needs. Pipe marker options include self-adhesive markers, snap-around marker styles and even  pipe markers that are recommend for harsh environments, indoor or out.
