This potable water expansion tank is used on gas, oil, electric, indirect fired, commercial water heater and hot water storage tank applications to absorb the increased volume of water created by thermal expansion. It also maintains balanced pressure throughout the water supply system by keeping system pressure below the T&P relief valve setting. This carbon steel tank with field adjustable air charge is built with ASME Section VIII construction, tank volume 45 gal, pre-charged to 40 psi, has fixed FDA approved butyl rubber diaphragm and 1 in stainless steel male NPT inlet connection and a 0.302 to 32 in charging valve connection (standard tire valve) to facilitate on-site charging of the tank to meet system requirements. An expansion bladder prevents air to water contact in the tank ensuring a long system life.
