As part of the \u003cstrong\u003eSX-60V\u003c\/strong\u003e series, this unit acts as a buffer to absorb excess system volume, effectively preventing the activation of pressure relief valves and minimizing the need for constant water make-up.\u003c\/p\u003e\u003cp\u003eThese diaphragm tanks utilize a flexible internal bladder to separate the system water from a compressed air cushion. This design ensures that the system charge pressure remains consistent, protecting mechanical components from stress and fatigue while maintaining optimal thermal efficiency throughout the piping loop.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Stabilizes internal system pressure to prevent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid Management:\u003c\/strong\u003e Accommodates thermal expansion to ensure consistent, reliable system operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency Protection:\u003c\/strong\u003e Reduces unnecessary water make-up cycles to maintain treated fluid chemistry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Engineered for long-term reliability in high-demand hydronic environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial and residential hydronic heating systems, radiant floor loops, and chilled water cooling circuits requiring stable expansion control.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133382787166,"sku":"572018-007","price":742.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/572018_007_image_84ba48e8-2a83-4adc-84c8-6e668c123b54.png?v=1786104993","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-572018-007-sx-60v-diaphragm-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
