Armstrong AX-280V - AX-280V ASME Pre-Charged Diaphragm Expansion Tank

Efficiently manage thermal expansion in your commercial hydronic heating or cooling system with the Armstrong AX-280V ASME expansion tank. This high-performance vessel is engineered to stabilize system pressure by accommodating the volumetric changes that occur as water cycles through temperature fluctuations, ensuring long-term operational stability for your mechanical infrastructure. The 572005-109 model is specifically built to meet rigorous ASME standards, providing a durable solution for demanding building environments.

These expansion tanks utilize a flexible diaphragm to separate the air cushion from the system water, effectively preventing waterlogging and reducing air infiltration into the piping network. By leveraging compressed air to maintain precise pressure, the unit automatically accepts and expels water as it heats and cools, significantly reducing the required footprint by up to 80% compared to traditional non-diaphragm designs.

Key System Performance Baselines:

• Pressure Regulation: Maintains consistent system pressure to prevent relief valve discharge.
• System Longevity: Protects piping and components by minimizing fluid expansion stress.
• Space Efficiency: High-density diaphragm design allows for compact mechanical room footprints.
• ASME Compliance: Built to meet industry-standard boiler safety and pressure vessel regulations.

⚠️ Application Profile: Ideal for commercial boiler systems, chilled water loops, hydronic heating networks, and high-performance building climate control systems.
