Energy savings
Electrolux energy saving system, as
standard on versions “A” & “B”, cuts
heating costs by half and saves
between 20 to 30 kW/h:
•The energy saving device reduces the
electric consumption by pre-heating the
incoming cold water using the steam from
the dishwasher and part of the used
rinsing water, without increasing the
heating elements in the boiler
• During the dishwashing process, the
machine is taking in cold water via the
condenser and at the same time the
exhaust fan is extracting the steam,
generated in the rinsing and washing
zones, forcing it to pass through the
aluminium lamellas of the condensing
unit. The steam condenses on the cold fins
and the heat is transferred to the cold
incoming water. The water temperature is
increased from ~ 10 °C to ~ 50 °C, that
means an initial energy saving by heating
up the incoming water of ~ 40 °C.
Incoming cold water 10°C
Air temperature 25 °C
Steam 68°C
Used water 68°C from DUO
Fresh water 54°C to booster
Used water 40°C from ESD
to pre-wash tank
Fresh water from CU 35°C
to pre-wash tank
• The extra price of an “A” or “B” version
compared to a “C” version will normally
be repayed within one year of use, taking
in consideration energy savings and the
fact that a ventilation hood is not
required

Rinsing system
Electrolux offers 2 final rinse methods:
• The Duo rinse system, standard on all
models, which guarantees an excellent
rinsing performance and also saves rinsing
water, rinse aid and energy by using the
same water twice
• The twin high temperature system, as an
optional alternative for customers who
require a higher level of sanitization or
those who need to wash large boxes

Detergent savings
Detergent saving system:
When the dishwasher is running at full
capacity, the water in the tanks is
continuously replaced by a flow of water,
coming from the final rinse zone and, at
the same time, the equivalent amount of
water is drained off via the drain-pipe in
the pre-wash tank. Electrolux FT
dishwasher has been designed to control
this flow system in order to keep the right
rate of detergent in the washing water
longer than the traditional machines.
• In traditional flight type dishwasher all
the water from the final rinse runs over to
the pre-wash via the wash tank. As the
washing water is replaced at the rate of
300-400 litres per hour, new detergent
must be added to maintain the required
concentration
• The equivalent flow in the new Electrolux
flight type dishwashers is only 100 litres
per hour. This means saving approx. 0,5 kg
detergent per hour! The savings, making a
calculation, based on working 7 hours/day
for 300 days, considering that the right
concentration of detergent is 2 grams per
litre, are more than 1 ton of detergent per
year (1479 kg/year with a traditional
machine vs 420 kg/year with the
Electrolux FT dishwasher)

Combined Flight Type Dishwasher
• The Combined Flight Type WT730 TCW
dishwasher has a
completely automated system that will
take care of both trays and cutlery, thus
eliminating the need for extra workers.
Not only will costs be dramatically cut,
but operational workflow will also be
improved
• The WT730 TCW dishwasher offers the
possibility to process up to 1500 trays/h
• The WT730 TCW dishwasher is made of
a special conveyor belt with two different
tracks – one for trays and one for cutlery.
The trays and cutlery will be fully
automatically loaded from a cord
conveyor
• Both trays and cutlery are collected at
the unloading stage by: a lowerator for
the trays and a trolley with stainless steel
rack for the cutlery
As an option, it is possible to set up the
machines so it collects trays from the
unloading station to two lowerators,
which will give the operator more time to
change the full lowerator.
