This critical component serves as a buffer to accommodate the fluctuations in fluid volume that occur as water temperature changes, preventing dangerous pressure spikes and ensuring the longevity of your system's piping and boiler infrastructure.\u003c\/p\u003e\u003cp\u003eInside the tank, a flexible diaphragm separates the system water from a pre-charged air cushion. As the system heats up, the expanding water compresses the air cushion within the tank, maintaining stable pressure levels. When the system cools and water contracts, the air cushion forces the fluid back into the piping, preventing air intake and suction-side pressure drops.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Absorbs thermal expansion to keep system pressure within safe operational limits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Separation Support:\u003c\/strong\u003e Minimizes the risk of air pockets in the hydronic loop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability Design:\u003c\/strong\u003e Engineered with high-quality materials to resist internal corrosion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for residential and light commercial hydronic heating systems, radiant floor heating loops, and closed-loop chilled water applications requiring precise pressure maintenance.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133406052446,"sku":"573100-006","price":4898.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/573100_006_image_fdee931d-9633-4bc5-8218-a17d6ec85c58.png?v=1786105340","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-573100-006-a200-l-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
