Stainless Steel Expansion Tanks

Stainless steel expansion tanks, also called expansion vessels, are designed to protect closed water-heating and potable systems in environments sensitive to corrosion and in applications requiring strict sanitation and hygiene standards. The anti-corrosive features of stainless steel make these tanks an ideal solution for marine applications, coastal geographic zones and industrial processes exposed to harsh chemicals. In addition to durability, stainless steel expansion vessels also offer ease of disinfection, resistance to biological reactions and negligible toxicity. This bundle of features makes stainless steel expansion vessels suitable for medical, public health, food processing and many other applications.
