It provides permanent separation of air and water through a removable heavy-duty Butyl rubber bladder housed in a fabricated steel shell. The shell is designed and constructed per ASME Section VIII Division 1. Each unit ships factory pre-charged to job specifications with a standard bladder rating of 125 PSIG. Licensed mechanical contractors and hydronic system specialists are the primary installers for this tank in commercial and industrial applications.\u003c\/p\u003e\u003cp\u003eThe cbx425-125 is rated for use in hydronic systems as well as non-potable, hydro-pneumatic, and drawdown applications. Its vertical-only installation orientation makes it well suited for mechanical rooms where floor space is limited but overhead clearance is available. The 112-gallon volume accommodates larger system water volumes where thermal expansion control is critical to maintaining stable system pressure and protecting components from overpressure conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e112-gallon (425-liter) tank volume for high-capacity hydronic applications\u003c\/li\u003e\n\u003cli\u003eRemovable heavy-duty Butyl rubber bladder ensures permanent air and water separation\u003c\/li\u003e\n\u003cli\u003eFabricated steel shell designed and constructed per ASME Section VIII Division 1\u003c\/li\u003e\n\u003cli\u003eFactory pre-charged to job specifications at the standard 125 PSIG bladder rating\u003c\/li\u003e\n\u003cli\u003eOptional 150 PSIG (1,034 kPa) bladder available for higher-pressure system requirements\u003c\/li\u003e\n\u003cli\u003eVertical installation only — engineered for upright mounting orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in hydronic systems and non-potable, hydro-pneumatic, and drawdown applications requiring a large-volume vertical bladder expansion tank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified mechanical contractor familiar with hydronic system design and local plumbing or mechanical codes. Shut down and depressurize the system before connecting or servicing the tank. This tank is rated for vertical installation only — horizontal mounting is not permitted. Verify that the system's pre-charge pressure matches the tank's factory setting before placing the system back into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Volume\u003c\/strong\u003e: 112 gallons (425 liters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Bladder Pressure Rating\u003c\/strong\u003e: 125 PSIG (862 kPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Bladder Pressure Rating\u003c\/strong\u003e: 150 PSIG (1,034 kPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBladder Material\u003c\/strong\u003e: Butyl rubber (removable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Material\u003c\/strong\u003e: Fabricated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Standard\u003c\/strong\u003e: ASME Section VIII Division 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Orientation\u003c\/strong\u003e: Vertical only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Hydronic, non-potable hydro-pneumatic, drawdown\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TACO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: cbx425-125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TACO","offers":[{"title":"Default Title","offer_id":51672274829618,"sku":"CBX425-125","price":15721.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f82f56c18e929e8bd4a0c4fb305db89.webp?v=1787965384","url":"https:\/\/voomisupply.com\/products\/taco-cbx425-125-vertical-bladder-expansion-tank-112-gal","provider":"Voomi Supply","version":"1.0","type":"link"}
