Linea NE flight dishwashers
Linea NE is the top of the Comenda range. It is the ideal solution for large cafeterias,
hospitals, hotels, in-flight catering and any other situation where there are significantly
large and continuous work loads.
There are eight standard Linea NE versions but thanks to the numerous additional options
and customised installations, no washing problem is too big for this range.
The Linea NE incorporates advanced technologies and ensures high-quality cleanliness,
significant water, energy and detergent savings, incomparable hygiene and the best
operating flexibility and safety.

This saves both energy and water.

The slanted bottom promotes the

is also included for specific needs. The
wide working dimensions (620x430 mm)
can accommodate various types of
dishes and objects.

prewash plus
Additional pre-wash area where a part
of ecorinse water is reused.
This process provides dual savings
and is environmentally friendly.
In fact PreWash Plus:
• saves on detergent: its concentration is
partially diluted since only a part of the
rinse water is diverted to the wash area
• reduces filter cleaning frequency since
the pre-wash area is kept cleaner
• dilutes chemical additive concentration
sent to the drain.
8
heat pump
Normally flight dishwashers are connected
to 50 ºC warm water mains. This is no
longer required thanks to the heat pump.
Infact the machine is connected to the
cold water mains. This reduces installed
electrical power from 25 to 35 kW/hour
according to the machine model.
Another advantage is the slight reduction
in humidity and heat dispersion providing
improved working conditions due
to a dryer and cooler work area.
9
electronic control panel
The user friendly LCD display control
panel can be used to set and monitor the
various washing phases and indicate any
malfunctions. In this version it is mounted
on the front of the drying unit.

RCD Rinse Control Device
Guarantees an excellent rinse even with
low pressure water flow. RCD complies
with severe backflow prevention specified
by WRAS and DVGW.
