In addition, there are several other subsystems, each focusing on a specific area. The

Washing systems offer a wide range of solutions, using the most up to date technology

and following the highest production standards, designed to guarantee the maximum

safety guidelines.

High quality performance and reliability, this is what the ZANUSSI Professional dishwashing

systems offer, proof of a level of quality which has become a benchmark in the world of

catering. Rack type dishwashers are integrated by a complete and well-organised series of

accessories. All the machines meet current safety, ecological and ergonomic standards

and are made of the strongest, most resistant materials. All components are designed

to guarantee the highest standards of hygiene as well as a long, trouble-free and silent

working life, even with high work loads. Just a few simple operations are required to use

the machine and the electronic models are equipped with an autodiagnosis system that

constantly controls the appliance, a valid aid for anyone already working under pressure.

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.

Modular rack

type dishwasher

The range of MODULAR RACK TYPE

DISHWASHERS includes:

Modular Level A models with electronic controls,

ACTIVE, Energy Saving Device, two speeds and

stainless steel wash pump, electric, with right or

left loading.

Modular Level B models with electronic controls,

ACTIVE, two speeds and stainless steel wash

pump, electric, with right or left loading.

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 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.

Duo Rinse system

Ease of use

Thanks to the electronic control panel, both speeds can be

fine tuned on-site.

Drainage quantities and frequencies are all variable by

the electronic control panel in order to maximize washing

performance with minumum water consumption.

A clear user interface makes the machine

easy to use for any operator. The light

turns green when optimal rinse conditions

are met.
