Equipped with ExpanView, a tank integrity indicator alerting the ASME fixed bladder thermal expansion tank top connection. BFA series Expanflex type BFA thermal expansion tanks, equipped with an ExpanView tank integrity indicator, are designed for use on potable hot water systems to absorb expanded water and prevent the dangerous build-up of pressure. As the water is heated, thermal expansion occurs and the water is forced into the precharged thermal tank. The precharged air cushion returns the water to the system when delivery is required at various fixtures. This arrangement prevents unnecessary relief valve operation, which results in wasted water and energy costs and eliminates potential internal components damage to water heaters.
