Armstrong 573100-010 - A600-L Bladder-Type Expansion Tank

Efficient hydronic system management starts with the reliable 573100-010 Armstrong A600-L expansion tank. Designed to absorb thermal expansion within closed-loop heating and cooling circuits, this unit prevents dangerous pressure spikes and reduces the frequency of relief valve discharge, ensuring long-term integrity for your mechanical infrastructure.

The vessel functions by utilizing an internal diaphragm that separates the system fluid from a compressed air cushion. As temperatures rise and water expands, the diaphragm compresses the air charge, allowing the system to maintain a stable operating pressure range throughout the heating or cooling cycle, which significantly extends the service life of pumps and piping components.

Key System Performance Baselines:

• Pressure Regulation: Maintains consistent system pressure to prevent hydraulic shock.
• Thermal Management: Accommodates fluid volume changes caused by temperature fluctuations.
• Corrosion Prevention: Minimizes oxygen contact with system water to preserve piping longevity.

⚠️ Application Profile: Ideal for commercial hydronic heating systems, chilled water loops, and large-scale industrial fluid management where consistent pressure monitoring is essential for safe operation.
