The LER range consists of 19 models with a cooling
capacity range from 40 to 420 kW and is available in a
standard or silenced acoustic version.
The possibility of setting up different cooling circuits in
units of the same power means being able to personalise
efficiency levels under full or part load conditions and the
redundancy. Three different efficiency packs are available:
• 1 cooling circuit, 2 compressors
• 2 cooling circuits, 2 compressors
• 2 cooling circuits, 4 compressors
The LER units are developed in a completely enclosed
version for a low noise operation making it possible to
install them in non-segregated environments. They are
characterized by a rounded shape contributing to an
attractive appearance.
The possibility of keeping the evaporator indoors means
there is no need to add glycol to the water inside
the system, which brings clear benefits in terms of
thermodynamic efficiency, protection against corrosion
and respect for the environment. In addition, you can
keep all components requiring maintenance in an easily
accessible room.
In air-conditioning applications it is often requested
to have heat available for heating sanitary water or
controlling post-heating in air-handling units where
independent temperature and humidity control is
required. all the cooling only units of the LER series are
available on request with desuperheater for partial heat
recovery; the available thermal power, which can, for
example, be used to produce domestic hot water or for
post-heating heat exchangers, depends on the unit’s
operating conditions.
PLUS
Electronic expansion valve
Up to 4 compressors
1 or 2 cooling circuits
Remote connectivity with the most common
protocols
Compact dimensions
Low noise levels due to the panelling
The LER units and the remote
heat sink are connected with
refrigerant lines whose length
can exceed the conventional
limits by using a specific kit
for oil recovery and creating
siphons distributed on the
lines.
