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
