ZEUS SUPERIOR
- STORAGE TANK
This AISI 316L STAINLESS STEEL storage tank has a useful capacity of 60 l.
It consists of an external sleeve enclosed at the bottom by a flange fixed by 12 screws.
A STAINLESS STEEL cylindrical pipe with a concentric spiral shape (
coil
) is inserted inside and is coiled
along all the height of the storage tank.
Heat is exchanged between the hot water in the primary circuit and the water contained in the cylinder
through the walls of the coil.
This keeps the water in the cylinder at a constant temperature and guarantees instant availability of domestic
hot water on demand
(21.000, 24.000 e 27.000 kcal/h according to the versions)
.
If necessary, the coil can be removed from the storage tank after taking off the lower inspection flange.
The following devices ensure that it operates correctly and is maintained in good condition:
Anode (1)
It is inserted in the storage tank and protects it against the
action of galvanic currents.
It is screwed onto the external sleeve at the bottom of the
storage tank.
Polyphosphate metering unit
(optional)
This prevents any limestone deposits from accumulating on
the walls of the coil.
The special kit is mounted on the domestic cold water circuit
inlet.
Gaudium Magnum (6)
(see description and operation Gaudium Magnum)
Recirculation kit
(optional)
This is used to connect the pipes of any recirculation system
of the domestic hot water circuit.
It consists of a pipe that is inserted into the tank after having
removed the anode with relative plug.
When the kit is installed, the anode must be screwed to the end
of the pipe.
Domestic hot water NTC sensor (NB) (9)
This allows the printed control board to detect the temperature
of the water contained in the storage tank.
It is attached to the external wall of the storage and inserted
inside an immersion trap.
Maximum flow d.h.w limit temperature thermostat (3)
It is a clicson thermostat which supplies the solenoid valve of
the Gaudium Magnum device.
It is fitted on the external wall of the storage tank.
Safety valve unit (13)
This unit is located in the lower part of the cylinder near the
domestic circuit cold water inlet.
In addition to an 8-bar valve (10) that prevents the safety
pressure from being exceeded inside the storage, it also
includes:
- a filter, a cylinder drain valve with hose fitting (12) and a
one-way valve
(“5” domestic circuit)
to prevent a pressure
increase following heating of the domestic circuit hot water
from causing water to return toward the water mains.
Domestic hot water circuit expansion vessel (11)
It compensates for volume variations following heating of the
water contained in the cylinder.
It is connected to the safety valve unit and has a capacity of 2 l
at a pre-load pressure of 3.5 bar.
