This high-performance vessel is designed to accommodate the expansion of thermal fluid as it heats, ensuring your system operates within safe pressure parameters while extending the service life of critical components like circulators and heat exchangers. Featuring the robust \u003cstrong\u003ePAX215-150\u003c\/strong\u003e design, this tank offers reliable volume control for closed-loop installations.\u003c\/p\u003e\u003cp\u003eThe internal bladder mechanism provides a complete physical barrier between the system water and the air charge. This separation prevents water logging, minimizes corrosion, and eliminates the need for frequent manual air adjustments. When the system temperature rises, the expanded water enters the bladder, compressing the pre-charged air cushion to absorb the increase in volume and stabilize total system pressure.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Precisely manages thermal expansion to maintain stable operating pressures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Prevention:\u003c\/strong\u003e Internal bladder isolates system water from air contact to reduce oxidation risks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Longevity:\u003c\/strong\u003e Helps minimize cycling stress on boilers and sensitive control valves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Fulfillment:\u003c\/strong\u003e National Boiler Supply offers same-day shipping on all in-stock units.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for use in commercial hydronic heating systems, radiant floor heating zones, closed-loop chilled water circuits, and large-scale residential boiler configurations requiring heavy-duty expansion capacity.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43136937099358,"sku":"PAX215-150","price":4477.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/PAX215_150_image_46d18676-9f5b-4102-8584-7bddff2f1875.png?v=1786156072","url":"https:\/\/nationalboilersupply.com\/products\/taco-pax215-150-bladder-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
