    Expansion Tanks for Drinking Water

    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.

    Expansion Tanks for Lubricants

    A rolling rubber diaphragm maintains tank pressure at or near 0 psi, which extends seal life to help keep lubricants clean. Use these tanks to accommodate the expansion of heated lubricants and provide a cushion of compressed air in closed lubricant-heating systems. They prevent lubricant loss by eliminating the need to expel hot lubricant from systems during each heating cycle.
