This critical hydronic component is engineered to absorb volumetric changes in system water, ensuring consistent pressurization throughout varying operating cycles. By integrating this \u003cb\u003eSeries B-200\u003c\/b\u003e unit, facility managers and technicians can rely on a robust, pre-charged pressure vessel designed for longevity and optimal performance in commercial hydronic environments.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a high-strength, heavy-duty bladder that effectively isolates the system fluid from the vessel walls. This internal barrier is the primary defense against common maintenance issues such as tank corrosion and water logging. Because the system water is fully contained within the bladder, the vessel maintains its pre-charge integrity significantly longer than traditional non-bladder tanks, reducing the need for frequent manual air adjustments.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eASME Construction:\u003c\/b\u003e Certified to rigorous ASME Boiler and Pressure Vessel Code standards for safety and reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBladder Design:\u003c\/b\u003e Advanced heavy-duty internal membrane separates water from steel for superior corrosion resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSystem Pressurization:\u003c\/b\u003e Maintains consistent pressure levels to protect pump seals and piping infrastructure from thermal stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePre-Charged Efficiency:\u003c\/b\u003e Factory-configured for rapid, streamlined installation into existing hydronic loops.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial heating and chilled water systems, large-scale residential boiler installations, and industrial closed-loop hydronic networks requiring ASME-rated expansion control.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43124009566302,"sku":"116051","price":4018.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/116051_image_c68e49e2-0ba0-4fb6-856c-9e72fe0b60f1.png?v=1786028174","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-116051-series-b-200-asme-pressurized-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
