Zilmet 300 Litre Vertical Potable Expansion Vessel ZI-318300
Theses are compact expansion tanks for sanitary hot water with a fixed potable water butyl membrane and an internal epoxy coating. These tanks are provided with a stainless steel fitting. MIG welding eliminates sharp cutting edges inside the tank. The shape of the membrane is designed to avoid water stagnation and the growth of any bacteria. With an external epoxy-polyester coating the vessels are less liable to rust.
