LARGE CAPACITY STAINLESS STEEL TANKS 'MASTER INOX'

LONG-LASTING PRODUCT: Nickel-chromiummolybdenum STAINLESS STEEL DHW storage
tank, highly resistant to pitting caused by halogen elements such as chlorine in drinking water. This is
the material used to manufacture all of the models in our 'MASTER INOX' series.

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

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

EASY TO MAINTAIN: With access to tank interior through ND400 side manhole, for inspection and
cleaning.

EASY TO HANDLE AND TRANSPORT: Our 'MASTER' storage tanks are designed for easy handling and transport to the place of installation. They have an integrated system for handling and
transporting by forklift truck, which facilitates handling operations enormously as there is no need to palletize the product which, given its weight and size, would make handling difficult. The tanks are also equipped with lifting eyebolts on the top part so that if they have to be placed in a high area they can be lifted with an overhead hoist.

'MASTER INOX' LARGE CAPACITY STORAGE TANKS With capacities from 1500 to 6000 litres these tanks are designed to provide an extraordinary storage capacity that translates directly into real savings.
Storage tanks ready for installation with plate heat exchanger and/or electric heating elements as the heating source.

'MASTER INOX' LARGE CAPACITY TANKS WITH COIL

ANTI-LEGIONELLA DESIGN: The design of the complete range of 'MASTER INOX' tanks adheres
to all of the "Treatment and Prevention of Legionellosis" criteria specified in current UNE standards
and EC Directives and, in particular, in the R.D.865/2003 and the RITE (Regulations on Thermal
Installations in Buildings). The anti-legionella design applies to the storage: tank unit and its internal DHW production system.

LARGE CAPACITY VITRIFIED TANKS 'MASTER VITRO'

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.

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

STAINLESS STEEL TANKS 'GEISER INOX'

LONG-LASTING PRODUCT: Nickel-chromium-molybdenum STAINLESS STEEL DHW storage tank, highly resistant to pitting caused by halogen elements such as chlorine in drinking water.
This is the material used to manufacture all of the models in our “GEISER INOX” series.

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

'GEISER INOX' DOUBLE WALL TANKS

SELF-CLEANING EFFECT: Corrugated design of the DHW storage tank, in constant vertical movement depending on the fluctuations in the internal pressure, which helps to detach any
limescale from the walls.

ANTI LEGIONELLA DESIGN: Totally uniform DHW storage temperature, with no cold zones inside the storage tank. The surround heating of DHW produces a uniform water storage temperature
throughout the whole of the tank, which in turn allows it to be used to its full capacity.

MAINTENANCE-FREE: DHW tank without any internal heat exchange elements. It does not require cathodic protection in normal drinking water conditions. The models with electric heating
have the heating element in the primary circuit so there is no risk of corrosion or lime scale.

LARGE DHW PRODUCTION CAPACITY: The heat exchange area
is that of the total surface area of the DHW storage tank.
