These tanks meet NSF/ANSI Standard 61 for use with drinking (potable) water. Use them to accommodate the expansion of heated water and provide a cushion of compressed air in closed water-heating systems. All of these tanks have a diaphragm, which completely separates air and water. They prevent water loss by eliminating the need to expel hot water from systems during each heating cycle.
