If you’ve spent any time around industrial ammonia refrigeration, you’ve seen a shell-and-tube heat exchanger. It is one of the most common ways to transfer heat between two fluids without letting them mix, and it appears throughout ammonia systems. Shell-and-tube heat exchangers show up all over industrial ammonia refrigeration because they can serve many duties in one durable package. You may see them as water-cooled condensers, where hot, high-pressure ammonia vapor is con
I’ve been in a lot of facilities that technically have piping colors, but no visual legend to explain what those colors actually mean. Especially as a recent graduate getting started in the ammonia PSM industry, which turned machinery rooms into instant mazes instead of functional workspaces. You’d see blue, yellow, orange, and green everywhere—but without a key, none of it told a story. It was just paint on the pipe. In an ammonia machinery room, piping density is high, and
For facilities operating ammonia refrigeration systems, January 1, 2026, is more than a future date on the calendar. It represents a clear line between proactive compliance and regulatory exposure. By that date, existing ammonia refrigeration systems are expected to have completed a Minimum System Safety Evaluation (MSSE) in accordance with IIAR 9. This is not a theoretical expectation or an optional safety exercise. Failing to complete An MSSE is a compliance issue with real
In modern industrial refrigeration, reliability and capacity are critical. Among the various compressor designs available, rotary screw compressors have become the preferred solution for large-scale applications. Their ability to deliver high capacity with fewer moving parts has made them a cornerstone of today’s industrial refrigeration systems. Understanding Rotary Screw Compressors Rotary screw compressors were originally developed in the 1930s; however, early versions we
