The Zanussi Modular rack type dishwashing range combines
superior strength, top washing performances, easier cleaning
and substantial costs savings thanks to the reduction in
water, detergent and energy consumption. It is
ideal for heavy usage installations such as hotels,
restaurants, canteens, hospitals and nursing homes.
The range is entirely built on a stainless steel subframe.
The machine incorporates a top of the range stainless steel
wash pump for added assurance. All doors are rigidly foam
insulated to provide additional solidity as well as to reduce
noise dispersion.
Maximum hygiene and no odours are guaranteed by the
self-draining wash pump while the pressed tanks in the pre-
wash, wash and rinse zones are sloped toward the drain to
prevent dirt built up.
The Ideal Washing System (IWS) is designed to wash
every item perfectly thanks to separate modules of pre-
wash, wash and rinse. This allows to maintain the best
working conditions in each phase. The Autostart function
(equipped in pre-wash and rinse tank) ensures no water and
energy consumption during stand-by periods.

Cost savings
The overall running costs are reduced by the unique wash
and rinse system which minimises water, energy and
detergent consumption.
When the water becomes too dirty to wash, the IWS, Ideal
Washing system avoids draining completely all the wash
tanks. A part of the dirty water is drained away automatically
each hour and topped up with clean water on a predefined
basis so the appliance can work all day long.
Water saving is up to 30%, while the detergent
consumption is reduced up to 75%. Indeed, the separate
pre-wash zones does not use heated water and so requires
no additional water for cooling.
Savings up to 12kW are guaranteed by the Energy saving
Device which incoporates a large condenser unit that is able
to pre-heat incoming cold water up to 50°C and to avoid the
need for a dedicated ventilation hood.
Self-draining stainless steel
washing pumps, suitable for
heavy duty installations, allow
complete discharge of the
dirty wash water.
The Maximum Water
Contact (MWC) wash
arms are positioned
along the full length of
the wash tank to wash
in the shortest possible
space. Thus doubling
the amount of wash
water contact time
in comparison to the
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.
The duo wash pump supplies the upper and lower
wash arms, concentrating as much high powered
wash water as possible, ideal for dried on foods or
for a large number of containers or utensils to be
washed.

The Duo rinse system ensures complete detergent removal

The Ideal Washing Performance (IWS) consists of separate
modules for pre-washing, washing and rinsing, this allows
to maintain the best working conditions in each washing
phase.
The pre-wash zone is now completely detached from the
detergent laden heated wash zone water, and uses only
fresh cold water, ideal to prevent protein food stuff from
sticking to the plates.
The wash zone is also physically separated from the rinse
zone (that in traditional systems is carried over from the
rinse area) so the wash tank is free of rinse aid which
typically weakens the working power of the detergent,
resulting in excessive detergent consumption.
The traditional dishwashers need to be completely drained
and re-filled at some stage, while the Ideal Wash System of
the Zanussi Professional Rack Type continues washing with
only a minimal quantity
of water, even during
long washing periods
which last several hours.
