Maintain stable pressure in your commercial hydronic heating or cooling system with the reliable Armstrong 572006-311 AST-125 ASME pre-pressurized expansion tank. Engineered for durability and high-performance, this vessel effectively manages water volume fluctuations caused by thermal expansion, protecting your system components from excessive stress and pressure spikes.
The unit functions by utilizing a sealed-in, heavy-duty diaphragm that separates the system fluid from a pre-charged air cushion. As system temperature rises, the excess fluid is pushed into the tank, compressing the air cushion; as the system cools, the air pressure forces the fluid back into the piping, ensuring constant system pressure and preventing air intake.
Key System Performance Baselines:
- ASME Compliance: Built to stringent ASME Section VIII standards for safety and pressure vessel reliability.
- Thermal Management: Efficiently absorbs volume increases to minimize safety valve discharge.
- System Protection: Reduces the strain on circulators, valves, and piping connections to prolong service life.
⚠️ Application Profile: Ideal for commercial boiler systems, closed-loop hydronic heating circuits, chilled water loops, and heavy-duty HVAC installations requiring consistent pressure regulation.
