This heavy-duty, pre-charged diaphragm tank is engineered to absorb the volumetric changes of water as it heats and cools, effectively protecting your plumbing infrastructure from damaging pressure spikes and reducing unnecessary stress on relief valves.\u003c\/p\u003e\u003cp\u003eThe unit features a high-grade heavy-duty diaphragm that creates an impermeable barrier between the system water and the air cushion. This separation ensures that the pre-charge remains stable over time, preventing the water logging issues common in non-bladder style tanks and maintaining consistent system pressure profiles across various temperature fluctuations.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Rated:\u003c\/strong\u003e Constructed to meet strict ASME Boiler and Pressure Vessel Code standards for safety.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Stability:\u003c\/strong\u003e Minimizes expansion and contraction cycles to extend the operational life of boilers and circulating pumps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragm Design:\u003c\/strong\u003e Heavy-duty, long-life diaphragm prevents air absorption into the fluid, protecting against corrosion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitive Versatility:\u003c\/strong\u003e Generous 86-gallon volume ideal for commercial and large residential hydronic installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily designed for closed-loop hydronic heating, chilled water cooling systems, and large commercial boiler circulation networks where precise pressure regulation is critical.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43127847780446,"sku":"1BN325LF","price":1085.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/1BN325LF_image_ae072fed-c113-429d-8d68-5c98148f0e71.jpg?v=1786058187","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-1bn325lf-pt-210v-86-gallon-asme-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
