This high-performance vessel is engineered to stabilize system pressure by accommodating the volumetric changes that occur as water cycles through temperature fluctuations, ensuring long-term operational stability for your mechanical infrastructure. The \u003cstrong\u003e572005-109\u003c\/strong\u003e model is specifically built to meet rigorous ASME standards, providing a durable solution for demanding building environments.\u003c\/p\u003e\u003cp\u003eThese expansion tanks utilize a flexible diaphragm to separate the air cushion from the system water, effectively preventing waterlogging and reducing air infiltration into the piping network. By leveraging compressed air to maintain precise pressure, the unit automatically accepts and expels water as it heats and cools, significantly reducing the required footprint by up to 80% compared to traditional non-diaphragm designs.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Maintains consistent system pressure to prevent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Longevity:\u003c\/strong\u003e Protects piping and components by minimizing fluid expansion stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpace Efficiency:\u003c\/strong\u003e High-density diaphragm design allows for compact mechanical room footprints.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Compliance:\u003c\/strong\u003e Built to meet industry-standard boiler safety and pressure vessel regulations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial boiler systems, chilled water loops, hydronic heating networks, and high-performance building climate control systems.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43136368541790,"sku":"AX-280V","price":6148.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/AX_280V_image_8f4cf44e-ae8a-4b19-a616-701ec957dfdc.png?v=1786130807","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-ax-280v-asme-pre-charged-diaphragm-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
