Expansion Tanks_Armstrong Armstrong Accessories

Armstrong Expansion Tanks are designed to reduce tank sizes by up to 80% over standard designs. Expansion tanks use compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Diaphragm or bladder tank designs isolate the expanded water from the pressure-controlling air cushion, which is pre-charged at the factory and can be adjusted in the field to meet final system requirements.

Applications

  • Pressure stabilization in water-based mechanical systems
    • Booster installations
    • Boiler systems
    • Chiller plants

Benefits

  • Lowest footprint compared to standard tank designs
  • Low operating expenses
