This high-performance expansion tank is designed to efficiently manage the thermal expansion of fluids within closed-loop hydronic heating and chilled water systems. The Armstrong 572006-305, also identified as the AST-60 model, is engineered to meet rigorous ASME code requirements, ensuring safety and structural integrity under demanding operating conditions.
By utilizing a heavy-duty diaphragm, this vessel separates the system fluid from the pre-charged air cushion. As temperatures rise and the fluid volume expands, the diaphragm flexes to accommodate the increase, effectively preventing pressure spikes that could otherwise compromise system components or lead to relief valve discharge.
Key System Performance Baselines:
- Thermal Expansion Management: Effectively absorbs volumetric changes to maintain stable system pressure.
- ASME Certified: Constructed to strict industry standards for pressure vessel safety and reliability.
- Heavy-Duty Diaphragm: High-grade elastomer construction ensures long-term separation between air and water.
- Pre-Pressurized Design: Factory-set charge simplifies field installation and reduces maintenance startup time.
⚠️ Application Profile: Ideal for commercial boiler systems, chilled water loops, and closed-loop HVAC hydronic installations requiring reliable ASME-rated pressure control.
