Efficiently manage thermal expansion in your hydronic heating or chilled water system with the Armstrong 572006-301, also known as the AST-12 ASME pre-pressurized expansion tank. This high-quality vessel is engineered to absorb the increase in water volume that occurs as system temperatures fluctuate, effectively preventing pressure spikes and protecting system components from premature wear or failure.
The tank utilizes a heavy-duty, field-replaceable bladder that acts as a secure barrier between the system water and the air cushion. This pre-pressurized design ensures that the water remains isolated, minimizing oxygen ingress and maintaining the integrity of your hydronic system while reducing the frequency of pressure relief valve discharges.
Key System Performance Baselines:
- ASME Construction: Engineered to meet rigorous ASME Section VIII pressure vessel standards.
- Bladder Material: High-grade, flexible heavy-duty rubber designed for longevity and chemical compatibility.
- System Protection: Effectively mitigates destructive pressure surges in closed-loop systems.
- Pressure Maintenance: Pre-charged internal air cushion provides consistent regulation during expansion and contraction cycles.
⚠️ Application Profile: Ideal for commercial and industrial hydronic heating systems, large-scale chilled water loops, and heavy-duty HVAC infrastructures requiring ASME-rated pressure containment.
