Adding to its line of expansion tank products, Taco, Inc. has introduced the CBX Expansion Tank, designed and constructed to the requirements of Section VIII Div. 1 of the ASME Boiler and Pressure Vessel Code. Each CBX tank is designed for vertical installation and incorporates a seamless molded butyl bladder, removing the possible loss of tank pre-charging pressure due to leaking at vulcanized seams. The tanks feature permanent separation of the system fluid and the pre-charged air section of the expansion tank, allowing for reduction in tank size, while the field accessible Schrader valve assembly allows for field adjustment of the pre-tank pressure.
