Taco cbx170-125 Vertical Bladder Expansion Tank 45 Gal

Product Description

The TACO cbx170-125 is a 45-gallon vertical bladder-style expansion tank designed for closed-loop hydronic heating and cooling systems. 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.

The 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.

Installation Notes

Installation must be in a vertical orientation only — horizontal mounting is not supported for this model. 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.
