Designed for durability and precision, this high-quality vessel provides the necessary capacity to absorb fluid volume increases caused by temperature fluctuations, effectively stabilizing system pressure and protecting your critical infrastructure from the strain of pressure spikes.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a high-performance diaphragm to separate the system fluid from the air cushion. As the water temperature rises and fluid expands, the diaphragm flexes against the pressurized air pocket, safely accommodating the excess volume and preventing unnecessary activation of pressure relief equipment or the loss of treated system water.\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 charge pressure to ensure reliable operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e Reduces the need for water make-up and avoids frequent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Protection:\u003c\/strong\u003e Prevents premature wear on system pumps and piping caused by rapid pressure shifts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRugged Design:\u003c\/strong\u003e Engineered specifically for long-term reliability in commercial hydronic applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for use in closed-loop hydronic heating systems, radiant floor installations, and chilled water loops requiring precise pressure management and volume control.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133385179230,"sku":"572018-008","price":1322.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/572018_008_image_5e2fd9f4-47f9-4c14-80bd-b7d1bf7548bc.png?v=1786105027","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-572018-008-sx-90v-diaphragm-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
