  • ASME vessels containing water and air under pressure.
  • Compressed air serves as a cushion, adjusting pressure as needed.
Air Replenishment
  • Small air compressor used to periodically replenish absorbed air volume.
Tank Characteristics
  • Large tanks are typically horizontal and have volumes of 2,000 gallons or more.
Operating Pressure
  •  Normal water system pressure: 60 to 75 psi.
  •  Common design pressure for hydropneumatic tank: 100 psi.
Functions
  • Provides a quick-demand water supply.
  • Regulates proper system pressure for efficient water supply system operation.
