The \u003cstrong\u003eCBX800-125\u003c\/strong\u003e vertical expansion tank from Taco utilizes a high-capacity 212-gallon design to effectively absorb expanded fluid volume, protecting your boiler and piping infrastructure. This reliable model, part of the reputable \u003cstrong\u003eCBX\u003c\/strong\u003e series, is engineered to handle the demanding requirements of commercial heating and cooling installations with consistent performance.\u003c\/p\u003e\u003cp\u003eThe tank features a heavy-duty, field-replaceable bladder that acts as a physical barrier between the system fluid and the air cushion. By isolating the system fluid from the air side, the tank prevents water logging and significantly reduces the rate of oxygen diffusion, which helps mitigate corrosion throughout the piping network. As system temperature fluctuates, the bladder flexes to accept or discharge fluid, keeping internal pressure within safe operating limits automatically.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Heavy-gauge steel shell provides structural integrity for long-term commercial duty.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Isolation:\u003c\/strong\u003e High-quality bladder material minimizes water-logged conditions and protects against system oxygenation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Stability:\u003c\/strong\u003e Large 212-gallon volume capacity reduces cycling frequency of pressure relief valves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance Accessibility:\u003c\/strong\u003e Vertical orientation allows for a smaller footprint while maintaining easy access to the charging valve.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for high-rise residential buildings, commercial chilled water systems, large-scale boiler installations, and secondary piping loops requiring robust thermal expansion management.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43136477724766,"sku":"CBX800-125","price":7912.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/CBX800_125_image_18a42955-c8c8-4f44-b82e-ad393d80007c.png?v=1786137932","url":"https:\/\/nationalboilersupply.com\/products\/taco-cbx800-125-212-gallon-vertical-bladder-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
