This sample legend shows the various pipe-marking colors used specifically with ammonia. These colors are using a universal language that helps anyone walking into the facility quickly understand what they are dealing with.

ent colors mean. It is about helping them understand why those colors matter. It is about building a culture where clear identification becomes second nature and where updating a worn out tag or pipe marker is as automatic as reporting a corroded pipe. Real understanding goes beyond memo rizing codes and refrigeration legends. The team needs to know why things are marked the way they are, what could happen if identifications are wrong or missing and how their daily actions help keep everyone safe. When people under stand the “why” behind the system, they are much more likely to be able to effec tively maintain it. Critical identification points Breaking down the key areas in a facility where proper identification is needed makes

a real difference. Starting with the compres sor deck, each piece of equipment needs clear marking showing its stage (high/low), the suction group it serves, and its critical operating parameters. Do not forget those oil separators and their return lines—mix those up, and you will have a mess on your hands. The condenser section needs proper identification of fan motors, water treat ment systems (if you are running evapora tive condensers) and all those head pressure control valves. Each pipe needs a clear mark ing showing the direction of flow, which is especially important when you are bleeding down pressure or pumping down a system. Over at your receiver area, level indica tors and pressure relief valves need clear, unmistakable markings. What about those transfer valves between receivers? They too need foolproof identification to prevent

accidental mixing or overfilling. And do not forget proper marking of your ammo nia detector locations and emergency venti lation controls. Seasonal considerations for identification systems Working in industrial refrigeration means dealing with dramatic temperature changes and environmental challenges. ID tags that work fine in winter might become unread able when summer humidity hits. Your outdoor markers need to withstand both scorching sun and freezing rain. During winter, when frost can build up on low-temp lines, your identification needs to remain visible, even under icy condi tions. Defrost cycle markers and hot gas lines require special attention, clear iden tification helps prevent accidents during manual defrost operations.
