This 4-gallon vertical bladder expansion tank is engineered to absorb excess pressure, preventing relief valve discharge and safeguarding your pumps and boiler components. By integrating this \u003cb\u003eCBX15-125\u003c\/b\u003e model into your setup, you ensure a consistent operating pressure, extending the lifespan of your entire hydronic installation.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a heavy-duty, field-replaceable bladder to create an impermeable barrier between system water and the pre-charged air cushion. As the water temperature rises, the bladder compresses the air within the tank, safely storing the increased volume without risking stress to the system piping. This compact design allows for easy vertical mounting in tight mechanical rooms while maintaining high-performance standards.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eConsistent Pressure:\u003c\/b\u003e Effectively minimizes pressure fluctuations during thermal cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBladder Integrity:\u003c\/b\u003e Features a heavy-duty design that prevents water-side corrosion and oxygen permeation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSpace Efficiency:\u003c\/b\u003e Compact 4-gallon vertical profile ideal for residential and light commercial mechanical spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurable Construction:\u003c\/b\u003e Built to withstand rigorous hydronic operating demands for long-term reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Designed for residential and light commercial closed-loop hydronic heating systems, radiant floor heating, and baseboard circulation networks where consistent pressure regulation is required.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43136471892062,"sku":"CBX15-125","price":2458.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/CBX15_125_image_48b95ad7-e3af-4cae-afb4-f33df1e5e161.png?v=1786137296","url":"https:\/\/nationalboilersupply.com\/products\/taco-cbx15-125-vertical-bladder-expansion-tank-4-gal","provider":"National Boiler Supply","version":"1.0","type":"link"}
