Optimizing your hydronic system's fluid management is essential for long-term reliability, and the Armstrong 572018-001 diaphragm expansion tank provides the perfect solution. Engineered to accommodate fluid volume fluctuations caused by thermal expansion and contraction, this tank ensures your system maintains consistent charge pressure during operational heating and cooling cycles.
The unit functions by utilizing an internal flexible diaphragm that separates the system water from the air cushion. As temperatures rise and fluid expands, the diaphragm flexes to absorb the extra volume, preventing nuisance activation of pressure relief valves and minimizing the need for unnecessary water make-up, which keeps system chemistry stable and reduces corrosion.
Key System Performance Baselines:
- Pressure Regulation: Maintains optimal system charge pressure to prevent unnecessary relief valve discharge.
- Thermal Management: Effectively absorbs expanded fluid volume resulting from temperature fluctuations.
- System Longevity: Reduces the frequency of water make-up, helping to minimize oxygen-rich water introduction.
- Durability: Rugged diaphragm design ensures consistent performance and long service life.
⚠️ Application Profile: Ideal for residential and light commercial hydronic heating systems, radiant floor heating, and boiler-fed cooling loops where steady system pressure is critical for equipment longevity.
