Accumulation and storage boilers for domestic and heating water
Emmeti accumulation boilers are manufactured in carbon steel S235JR with
bottom surface rounded through deep-drawing.
The tanks are assembled with precision automatic equipment, and welded
with continuous thread in Argon atmosphere and CO2 with "head" coupling.
Insulation dark grey colour.
For enamelled boilers with storage tank (organic enamelling):
- maximum operating pressure 6 bar
- maximum continuous operating temperature: 70 °C (95 °C peak for max 20
hours per year)
Glazed boilers with storage tank (inorganic enamelling):
- maximum operating temperature 10 bar (8 bar for 1500 and 2000 litres models)
- maximum continuous operating temperature: 95 °C
Emmeti accumulation boilers, accumulation tanks and heat exchangers are
in accordance with directive PED 97/23/CE "Pressure equipment"
in application of art. 3 codicil 3 of the above mentioned directive, to
be used with warm or cool water.
Resistance to corrosion
The protection against corrosion and suitability for human water
consumption, are obtained with:
- vitrified tanks: treatment of inorganic glazing (vitrification) as
required by the applicable regulations (DIN 4753-3 and UNI 10025);
- enameled tanks: organic enamelling (treatment with thermosetting resins).
The insertion of Boguard electronic anode (1/2 "M) provides further
protection of metal surfaces.
To guarantee the product for a proper corrosion protection, check or
replace every 6 months the magnesium anode where expected (for example
Tank in Tank).
To prevent the drilling of the boiler, it is to avoid the presence of
stray currents from external parties.
In this sense, provide the connection with appropriate dielectric joints.
In the case of boiler equipped with a magnesium anode, prepare the
grounding circuit to earth ground and such as to not itself determine
which inputs of eddy current towards the metallic mass of the boiler.
The warranty of sanitary boilers is bound bu the value of the electrical
conductivity of the water that must not be less than 150 µS or superior
at 1000 µS.
The failure to comply of the prescriptions, It will void the product warranty.
Suitable for drink water (only for domestic water models)
