The \u003cstrong\u003eArmstrong 572006-310 AST-100\u003c\/strong\u003e provides a robust solution for maintaining steady operational levels in demanding commercial environments.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a heavy-duty diaphragm to separate the system fluid from the pre-pressurized air cushion. As water expands due to heating, the diaphragm flexes to accommodate the volume, effectively regulating internal pressure and extending the lifespan of pumps, boilers, and piping components.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Compliance:\u003c\/strong\u003e Built to rigorous industry standards for pressure vessel safety.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Management:\u003c\/strong\u003e Efficiently offsets thermal expansion to minimize relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Integrity:\u003c\/strong\u003e Engineered with premium materials for long-term resistance against corrosion and fatigue.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for large-scale hydronic heating systems, chilled water cooling loops, and commercial boiler room installations requiring consistent pressure regulation.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133355786334,"sku":"572006-310","price":3848.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/572006_310_image_077cc457-95bf-496f-aff9-296c6967fe25.png?v=1786104697","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-572006-310-ast-100-asme-pre-pressurized-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
