Refrigerated Make-Up Air Unit Standards

Using two-part IIAR RMAU ammonia pipe markers to distinguish between certain ammonia system components, such as a refrigerated make-up air unit, and to shield personnel from exposures.

These ANSI A13.1 (ASME piping source) pipe marking standard-exceeding pressure-sensitive vinyl pipe labels are the recommended display for system components conveying dangerous chemicals, like ammonia.

Additionally, the labels adhere to IIAR Bulletin No. 114, which is a more comprehensive standard for marking ammonia system components.
