Armstrong AX-60 - AX-60 Pre-Charged ASME Expansion Tank

Maintaining optimal system pressure is critical for hydronic efficiency, and the Armstrong AX-60 pre-charged ASME expansion tank provides a reliable solution for residential and commercial heating or cooling loops. This robust vessel, model AX-60, is specifically engineered to absorb the expansion of fluids caused by temperature fluctuations, preventing safety valve discharge and protecting sensitive system components from pressure spikes.

The unit utilizes a flexible diaphragm that separates the system water from a factory-charged air cushion. As the water volume increases due to heating, the diaphragm compresses the air, allowing the system to expand without exceeding maximum operating pressure thresholds. This design significantly reduces overall tank size requirements compared to traditional non-bladder expansion tanks.

Key System Performance Baselines:

• Space Efficiency: Reduces total tank footprint by up to 80% compared to conventional atmospheric designs.
• ASME Compliance: Built to stringent ASME Section VIII standards for durability and safety in pressurized environments.
• System Stability: Maintains consistent operational pressure to extend the lifespan of boilers and circulators.
• Corrosion Resistance: High-grade materials designed to minimize internal degradation and water contamination.

⚠️ Application Profile: Ideal for commercial boiler rooms, high-capacity closed-loop hydronic heating systems, and industrial chilled water circuits requiring precise pressure regulation.
