Designed for commercial and industrial applications, this high-quality vessel effectively manages thermal expansion of fluids to prevent system pressure surges and protect critical components from premature wear.\u003c\/p\u003e\u003cp\u003eThe AST-210 series functions by utilizing a heavy-duty diaphragm that separates system fluid from the pre-charged air cushion. As water heats and expands, the diaphragm flexes to absorb the increased volume, maintaining safe operating pressure levels throughout the hydronic loop without relying on constant relief valve discharge.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Certified:\u003c\/strong\u003e Built to rigorous pressure vessel standards for maximum safety and durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Management:\u003c\/strong\u003e Efficiently absorbs volumetric changes to prevent wide pressure fluctuations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistance:\u003c\/strong\u003e Engineered with premium materials to ensure long service life in closed-loop systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial hot water heating systems, district energy loops, and industrial process cooling where consistent expansion control is required.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133355360350,"sku":"572006-308","price":5123.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/572006_308_image_884d2a07-77cb-4536-b871-dc6ca28096e4.png?v=1786104661","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-572006-308-ast-210-asme-pre-pressurized-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
