It provides permanent separation of air and water using a removable heavy-duty butyl rubber bladder housed in a fabricated steel shell constructed per ASME Section VIII Division 1. The tank arrives factory pre-charged to job specifications with a standard bladder rated at 125 PSIG. At 170 liters total volume, this unit is built for demanding commercial and residential hydronic applications where long-term system pressure management is required.\u003c\/p\u003e\u003cp\u003eThe cbx170-125 is intended for hydronic systems, non-potable hydro-pneumatic applications, and drawdown service. It is installed in vertical orientation only. Typical applications include large residential and light commercial heating and cooling hydronic loops where system expansion volume control and air-water separation are critical to system performance and longevity. This tank is specified and installed by licensed plumbing and mechanical contractors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-gallon (170-liter) tank volume for high-capacity hydronic expansion control\u003c\/li\u003e\n\u003cli\u003ePermanent air-water separation via removable heavy-duty butyl rubber bladder\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 time of manufacture\u003c\/li\u003e\n\u003cli\u003eStandard bladder rated at 125 PSIG (862 kPa); optional 150 PSIG (1,034 kPa) bladder available\u003c\/li\u003e\n\u003cli\u003eVertical installation only\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.

A licensed plumbing or mechanical contractor should install this tank in accordance with applicable local codes and ASME guidelines. Isolate the system and relieve pressure before connecting or servicing the tank. Verify system pre-charge pressure matches the tank charge specification before placing the system into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Volume\u003c\/strong\u003e: 45 gallons (170 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, heavy-duty)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Material\u003c\/strong\u003e: Fabricated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction 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\u003ePre-Charge\u003c\/strong\u003e: Factory pre-charged to job specifications\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: cbx170-125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TACO","offers":[{"title":"Default Title","offer_id":51672914526514,"sku":"CBX170-125","price":2816.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f82f56c18e929e8bd4a0c4fb305db89_4a6d55f6-b272-488f-a705-351bfdfc7d7e.webp?v=1787974985","url":"https:\/\/voomisupply.com\/products\/taco-cbx170-125-vertical-bladder-expansion-tank-45-gal","provider":"Voomi Supply","version":"1.0","type":"link"}
