The Ideal Wash System (IWS) is designed to wash every item perfectly the first time - 24 hours per day, 7 days a week.
The pre-wash zone typically contains the dirtiest water in the dishwasher and provides the base for perfect washing.
Unlike traditional systems, the Electrolux pre-wash is completely detached from the detergent laden heated wash
zone water and uses only fresh cold water to prevent protein based food stuffs sticking to the plates.
The wash zone is also physically separated from the rinse zone, (that in a traditional system is carried over from rinse area)
so the wash tank is free of rinse aid that typically weakens the washing power of the detergent; resulting in excessive
detergent consumption.

Even during long washing periods lasting several hours, where traditional dishwashers need to be completely drained
and re-filled at some stage, the IWS continues washing with only a minimal quantity of water being consumed.
Each machine has two pre-set speeds - slow for more baked on dirt, fast for lighter soiling; both speeds
can be fine tuned on-site via the electronic control panel to suit customer needs.
When the pre-wash or wash water becomes too dirty to wash effectively, a part of the dirty wash water is automatically
drained and replenished without stopping the dishwasher enabling continuous-all day washing. Drainage quantities and
frequencies are all variable via the electronic control panel in order to maximize washing performance with minimum water
consumption.

On 150 litre modules, the duo wash pump
configuration features one 2,2kW pump
supplying the upper wash arms, another
1,1kW pump supplying the lower wash
arms, concentrating as much high powered
wash water as possible - ideal for dried on
foods or where large number of containers
or utensils are washed.
In order to wash in the shortest possible
space, the Maximum Water Contact (MWC)
wash arms are positioned along the full
length of the wash tank. Thus doubling the
amount of wash water contact time in
comparison to traditional wash arm
configurations. Just because a basket is in
the wash zone for 2 minutes, it doesn’t
mean it is being washed in water
for 2 minutes.
Duo filter system minimises food debris
entering the wash water system, reducing
the need to regenerate water. The curtain
system prevents water splash over from
tank to tank.

The atmospheric duo rinse system with built-in air gap
is the benchmark for rinsing. Hot water at a constant
temperature in any conditions provides the peace
of mind that every washed item will be detergent free
and sanitised.
The tried and tested two stage rinse system,
the duo rinse, ensures complete detergent removal with
minimum water consumption - hot rinse even from the
2nd rinse created by additional 3kW electrical elements
in the duo rinse tank.
The Energy Saving Device is able to pre-heat incoming
cold water, saving up to 12kW in energy as well as
condensing the steam in the kitchen.

The solid 3mm thick stainless steel box
sub-frame provides long term sturdiness
with bolt-together construction that can be
split on-site for increased site accessibility.

with minimum temperature loss and
steam escape.

Touch button electronics provide notable benefits, whether for the operator, the owner or the engineer and also the user:
in order to avoid time-loss for the operator, the electronic control audibly and visually signals on the display, messages such as:
Door open - close the door / Warm up /Clean - cleaning cycle being performed / Drain /Wash /
Time-to-heat-up message from start up.
Electronic control panel
Pre-arranged for HACCP monitoring
equipment such as computers, printers and
modem for remote control.
Optional measuring of water, detergent and
energy consumption.

The green light provides the operator with
an immediate signal after every rinse cycle
informing that rinsing has been performed
to perfection.

The unique wash and rinse system minimises water,
energy and chemical usage to reduce overall running
costs.
The IWS avoids the need to completely drain all the
wash tanks when the water becomes too dirty to wash.
A part of the dirty water, typically 15 litres/hr, is drained
away and topped up with clean water on a predefined
basis (variable onsite) so the dishwasher can operate
all day. Water saving is up to 30%.
The separate pre-wash zone does not use heated water
and therefore requires no additional water for cooling.
Autostart ensures no water and energy consumption
during periods when dishwasher is on stand-by.
The boiler is insulated to avoid further heat loss.
The Energy Saving Device incorporates a large
condenser unit able to pre-heat incoming cold water to
50°C, saving up to 12kW as well as avoiding the need
for a dedicated ventilation hood.
