The Benefi t Makers
the benefi t makers
Elettrobar proposes an innovative generation of tunnel dishwashers intended to represent the new reference
standard of the sector in terms of advantages for the users and price performance ratio.
The Niagara rack conveyors are available in two set-up levels:
411 - entrance version with remarkable performance and consumption among the lowest in its category, to
1.3 lt/basket, offered with a highly favourable performance/price ratio
412 - version with most complete equipment, it allows 23% lower consumption with respect to the 411, to
1.0 lt/basket, it has greater versatility of use and higher production, thanks to the very advanced adaptive
rinse system
A compact but perfectly articulated range such as Niagara, allows each type of user to fi nd its own ideal
dishwasher, foe maximum washing effi ciency, as quickly as possible and with minimum installation and
operating costs.

There are many safety systems that intervene to protect the integrity of the
operator and dishwasher if:
• One of the doors is opened
• The plates exiting are not removed
• A drawer fi lter is extracted
• If an over-voltage or over-heating of a main electrical component
should occur.
• The belt or drive jams
• One or more heating elements operate in air

lower
operating
cost
Elettrobar dishwashers have very high washing
effi ciency and use technologies, many of which
are patented and which reduce minimum
consumption to 1.0 lt of water per basket (1.3
for the 411 series), with respect to the average of
dishwasher tunnels present on the market. This
means a reduction in consumption of around 40%.
Reducing water consumption means also reducing
the consumption of electricity and chemical
products. Other technologies and equipment act
on all factors that generate operating costs.
ProPortional
An adaptive product ProRinse
The water consumption adapts to the production
and the type of objects to wash; the electric power
absorbed with the production; the type of objects
to wash and the supply conditions. The result is
that the machine operating cost is, moment by
moment, that strictly necessary to obtain the
washing results and maintain hygiene.
It integrates different technologies to increase
the effi ciency of the use of water and reduce
consumption of the same, also adapting it to
conditions of use. It is supplied through a system
with break tank in compliance with the WRC
Standards; rinse pump with DuoFlow technology
with double outlet. Heating takes place via a boiler
with three Incoloy 800 alloy heating elements,
which feeds a pair of fi nal rinse arms through the
ProPortional fl ow change device.
4
Flow Change Device
Allows to change the water fl ow rate distributed
through the rinse arm in a way to adapt
and optimise consumption according to the
advancement speed. This gives rise to a saving
in water; depending on the program used it can
reach 20% with consequent savings also in terms
of energy, detergent and rinse-aid consumption.
HiTech Rinse Arms ProHeat Heat Recovery Device
Manufactured in ProComposit composite material
(matrix in resin with an isotropic load of glass fi bre
and micro-granules of talc); they are injection
moulded and welded with vibration technology.
Complex ducting is obtained, which promotes the
fl ow of fl uid, thus reducing pressure drops. There
are a different number and type of stainless steel
spray nozzles, obtained from precision mechanical
machining, depending on the type of rinse. The
composite arms are lighter, safe to handle, easy
to clean and with longer duration over time with
respect to the traditional steel arms.
The latent heat of the steam is used to heat the water before it enters the boiler, with an energy saving
which can reach up to 8 kW. It uses a centrifugal extractor that forces the steam through two copper heat
exchangers with aluminium fi ns, total exchange surface 50 m
the humidity introduced into the environment is greatly reduced, allowing the use of smaller external
extractor systems. Whenever water fi ltered through a reverse osmosis device is used, which irreparably
corrodes some metals, among which copper, the copper/aluminium heat exchangers must be replaced by
others in stainless steel, available on request with a surcharge.

. As well as the energy saving advantage,

high production
IdroWash2
Based on the 1.5 kW DuoFlow double outlet
pump, equivalent to a 2.0 kW traditional pump,
which feeds 36 IdroWash2 directional nozzles,
positioned on 3 arms measuring only 40 cm. With
this concentration of mechanical washing power,
the tableware undergoes a sort of “hydraulic
brushing”, which removes the dirt effi ciently. The
nozzles have positive impression which makes
the jet very narrow and stable. The energy of the
water is very concentrated when it strikes the dirt
and the mechanical washing action is maximum.
The many, closely positioned nozzles, ensure
perfect coverage. Very hot water is used: 60 °C in
the standard programs and 63 °C in the intensive
programs; the constant temperature is ensured by
an armoured heater in the tank.
Pre-wash XL ProWind Drying Basket conveyor
It is a heavy module with length of 820 mm, with a
complete IdroWash2 system with 3 arms. Most of
the dirt is removed here and the most consistent
fraction is collected by a drawer fi lter, which can
then be emptied in just a few seconds without
opening the door. A second separation takes place
in the ProStrainer surface fi lter, which is shaped in
a way to convey the dirt into a removable basket.
A third fi lter is found on pump suction.
It uses air at 70 °C, withdrawn from the outside
and heated by a 6 kW heat exchanger (optional
9 kW). A 550 W radial turbo fan sends a fl ow
of 1,400 m3/hour to two upper outlets. The air
blades also have the effect of maintaining the
steam inside the machine; drying is installed on a
cantilever-mounted module with length of 60 mm.
The use of dry air at a relatively low temperature
allows to treat even the most delicate glasses or
plastic materials safely, which would risk melting if
dried in a conventional dryer.
500 W advancement motor, conversion of
movement via eccentric or oscillating slide.
Basket guide with double lateral track to leave the
central area of the basket completely free for the
passage of the water; very thick stainless steel
oscillating fi ngers. The oscillating slide moves
on anti-friction plastic rolling material. Useful
dimensions of the basket passage mouth: 500
x 430 mm. Anti-slip safety with oscillating arm
and without friction disks in order to prevent any
damage to the conveyor system in the event of
accidental blockage of the basket. Set-up for
connection with end run stop microswitch. The
electronically-controlled double winding motor
makes four advancement speeds possible.

easy to clean
ProStrainer built-in fi lters
They are made in ProComposit composite material
(matrix in resin with an isotropic load of glass
fi bre and micro-granules of talc). With respect to
traditional components in steel, these very modern
parts are much lighter, elastic and safe to handle
because they do not have sharp edges and do not
heat up. If they are cleaned by beating, they do not
deform and do not become undulated, maintaining
their fi ltering capacity unchanged over time.
The pump suction fi lter is also made in the same
material, fi tted with a practical handle and lateral
tracks for easy manoeuvres. The fi lter is made up
from a fl at surface that tilts towards the outside,
thus to facilitate the running of solid waste collected
and from a basket into which the waste fl ows;
positioned in a way that it can be easily accessed
by the operator and emptied in just a few seconds.
Construction Accessibility
Fully-moulded self-cleaning wash tank, wash
chamber without internal piping, doors with
insulated and counter-balanced double walls that
are very light to lift. Easy to remove and replace
wash and rinse arms, module separation curtains
in plastic for use with foodstuffs which can be
removed without the aid of tools. Construction
with full double wall to reduce environment noise
pollution to less than 70 db.
All modules have fully opening counter-balanced
doors that allow easy access to any point of the
washing chamber. The electric and hydraulic
components are accessed for maintenance by
removing the front panelling, thus obtaining a
completely free surface also in this case.
Drawer fi lters
The pre-wash module and the washing module
have a drawer pre-fi lter that collects the excess
dirt eliminated by the “hydraulic brush”, before it
reaches the wash tank. The fi lter can be extracted
without opening the door and can be emptied in
just a few seconds. Its construction prevents dirty
water dripping onto the fl oor during extraction.
The organic waste does not end up in the
drain but can be collected and re-cycled. In the
machines with pre-wash, the second pre-fi lter
with dense mesh network progressively fi lters
the dirt, ProGressive, system and keeps the water
in the wash tank extremely clean, with obvious
advantages when washing glasses and particular
tableware.
7
user-friendliness
Large actual aperture
The new Niagara rack conveyor dishwashers have an actual aperture
of 45 cm, which allows easy loading using specifi c baskets, oven trays,
Gastronorm trays, heat-insulated trays for distribution of food, plates
also with large diameter, tall and valuable glasses, pans and various
utensils.
8
washing programs
Programmi
The dishwashers are fi tted with a series of specifi c programs for the different conditions of use. The
Foto Macherina accesa a
effetto
programs differ regarding temperature and power of the wash, the contact time, the temperature,
fl ow rate and rinse distribution. Therefore, differently from most competitor products, limits are
not given to just going “quicker” or “slower” but the percentage breakdown of the elements that
contribute to washing are really changed, optimising the process in a way to wash greater quantities
of tableware more effectively in a shorter period of time.
They are divided into:
STANDARD PROGRAMS SP
ProSmart Interface
It uses a LED screen with 4 digits and two variable
colour side bars. The interface allows to select
a wash program from the many available. The
tank and boiler temperatures and the number of
operating hours are demonstrated on request;
advanced self-diagnosis that includes an archive
of alarms intervened. The information is provided
via codes and brief messages. A series of menus
with protected access allows the technicians
to adjust each individual operating parameter,
the advancement speed of the tableware to the
washing and rinsing temperatures.
