Ammonia Pressure / Temperature Chart
by Jeremy Williams on Sep.21, 2020, under News
Ammonia saturation or pressure/temperature charts are commonly also known as boiling/condensing charts. As an operator/technician you will be using many different saturation charts for the various refrigerants and is an essential tool to understand what is going on inside the system. Pressure is the base of refrigeration and controlling pressure allows us to control temperatures.
Housekeeping and General Appearance – NH3 Machinery Rooms

At first if you don’t succeed, try again. Definitely a big difference from the original black died concrete. Next project is diamond plate going up around all curbs!
Housekeeping is extremely important and a system that does not look well maintained most likely is not well maintained. Here are some things you can look for when entering a compressor room that has process equipment:
- The area should not have an ammonia odor
- The area should be well lit
- The area should be clean and free of debris, puddles, etc…
- The area should not be used for bulk storage
- The equipment and piping should be clearly labeled
- The equipment should be free of visible corrosion
- The equipment should be free of excessive ice build-up
- Ammonia detectors should be in working order and free of obstruction
- Air intake for ventilation should be clean and free of obstruction
- The safety shower/eye wash should be clean and the path to it unobstructed
- and much more…
