MAXIMUM BONDING-MOLECULAR INTERACTION: Applying a sophisticated "surface treatment" to the metal surface together with an automated process for the application of the enamel, results in much more than just a good mechanical adherence of the lining. During the curing process a molecular interaction occurs between the steel surface and the enamel coat applied. This maximum bonding of the enamel coat to the steel surface and the high degree of impermeability
of the vitreous enamelling, guarantee the durability of the product and prevents the kind of deterioration that can occur with other types of coatings, such as the detachment or blistering of the protective coat.

LONG-LASTING PRODUCT: VITREOUS ENAMELLED STEEL storage tank according to           DIN 4753/3: Food grade impermeable lining with a porcelain look that protects the metal surface of the storage tank in contact with water.

FOOD GRADE: Vitreous enamelling is a food-quality, impermeable lining with a porcelain look that protects the metal surface of the storage tank in contact with water. All internal linings in DHW tanks must, by law, be "food grade" (EC Regulation 1935/2004). Our vitreous enamelling, in addition to food grade certification at the test temperature specified in current regulations (22ºC), has food grade certification at 120ºC, which guarantees its maximum quality at extreme working temperatures.

MAXIMUM WORKING TEMPERATURE: It withstands the maximum DHW storage temperatures that these types of installation (95º) handle, without any deterioration or detachment thanks to its capacity of molecular interaction with the steel surface. This treatment is carried out by applying an enamel (inorganic chemical product) by either a "dry" or "wet" method (depending on the type of tank and its internal geometry), and then carrying out curing in an oven at 850ºC.

EASY TO MAINTAIN: With access to tank interior through side and top holes, for inspection and cleaning. Models RB have a ND400 manhole on the side of the tank.

EASY TO INSTALL: Their dimensions facilitate access to enclosed spaces, even the models with capacities of 800 and 1000 litres, with a removable system for the insulation on the two opposite sides of the tank, allowing them access through 800 mm wide entrances.

CATHODIC PROTECTION: All of the CORAL VITRO models include cathodic protection which consists of magnesium anodes and an anode charge meter for control and maintenance purposes.
As an option these tanks can be fitted with "lapesa correx-up" permanent cathodic protection.

ELECTRIC HEATING: Ready to be fitted with Incoloy, low charge density electric immersion elements or with ceramic heating elements.

MAXIMUM STORAGE CAPACITY: Extra thick, rigid, PU mould-injected insulation that minimizes heat losses of stored DHW.
