Maintain optimal hydraulic pressure and protect your commercial heating or cooling system with the Armstrong 572006-302 AST-20 ASME Pre-Pressurized Expansion Tank. Engineered for durability and reliability, this unit effectively absorbs the thermal expansion of system fluids, preventing unnecessary pressure spikes and safety valve discharge.
The vessel features a high-grade butyl diaphragm that creates a positive barrier between the system water and the air cushion. This design eliminates waterlogging and minimizes corrosion by preventing oxygen absorption, ensuring consistent system operation throughout the life of the equipment.
Key System Performance Baselines:
- Pressure Management: ASME-rated construction for safety in high-demand commercial environments.
- Corrosion Prevention: Heavy-duty diaphragm design keeps fluid isolated from the air charge.
- System Stability: Maintains consistent operating pressure to prevent mechanical wear.
⚠️ Application Profile: Ideal for use in commercial closed-loop hydronic heating, chilled water systems, and radiant floor installations requiring strict adherence to ASME pressure vessel standards.
