Utilities systems supply the water, air, and energy required by a plant's process units, maintenance and shop equipment, and other facilities. Although not as complex as processing units, utilities systems can be large and expensive. A plant cannot operate safely and efficiently without the following utilities systems:

• Water supply
• Air supply
• Heat and fuel supply
• Refrigeration system
• Power supply

The Process Utilities Systems Part 1 training course concentrates on the water and air supply systems. It explains the design and function of plant water and air utility systems. This online course is part of the Process Utilities Systems training series.
