FEATURES AND BENEFITS
Flat top and low profile for best architectural
integration
The NEOSYS design is minded to be perfectly integrated into
urban or residential environments. The state of the art design of
NEOSYS includes a painted casing, a flat top that hides the fans
and aesthetic protection grilles.
The very low unit height less than two meters makes easier for
architects and design engineers to integrate the unit on a roof.
Many interviewed customers confirm that the state of the art
design of NEOSYS will replace any requirement of costly cladding
solutions around the unit.
Smarts acoustics with inverter fans
No more need to make a choice between a high efficiency version,
a low noise or an ultra low noise version. NEOSYS can adapt all
situations with only one version. NEOSYS is fitted in standard
with the Active Acoustic Attenuation System™ that is using an
electronic control associated with inverter fans. NEOSYS can
change automatically the speed of all the fans – from 0% to 100%
of the nominal air flow – to meet the building load requirements
while respecting maximum authorised noise level in the time zone.
NEOSYS is surely achieving the best acoustic signature of the
market thanks to the latest generation of Owlet™ high performance
aluminium fan blades and noiseless ceramic bearings.

FEATURES AND BENEFITS
A high energy performance
By using R410A refrigerant associated with high efficiency micro
channel coils and variable speed fans NEOSYS is contributing to
a very low energy consumption all year around with an average
energy efficiency ratio (ESEER)* in cooling mode above 4.0.
NEOSYS Heat-pumps are also achieving very high performances
in cooling and heating mode (COP* up to 3.2).
Furthermore NEOSYS advanced control allows energy savings
all year around by using smart control functions:
- Low water system quantity to reduce the time to reach the set-
point.
- Dynamic defrost (patented) to limit the number of defrost cycles.
- Set-point reset based on outside air temperature to relax the
chilled water set-point.
*ESEER : European Seasonal Energy Efficiency Ratio in cooling mode.
COP : Coefficient of Performance in heating mode.
R410A Micro channel heat exchanger
With the use of fully
aluminium coils already
used in the automotive
industry, NEOSYS offers
many customer benefits:
- Up to 40% less refrigerant
charge that contributes to
reduce the total amount
of refrigerant used in the
system.
- A more efficient system
(EER + 10%).
- An air heat exchanger
with significantly impro-
ved corrosion resistance
results (x 2) from the
same aluminium alloy (no galvanic action) vs. the traditional
copper tube/aluminium fin coils. By using this type of coil, units
can be used in light corrosive or seacoast environments without
any need for additional, and expensive, pre-treated fins or coil
coating.
- High mechanical resistance eases the cleaning with high pressure
air or water washers without any risk of damaging the fins.
Available in cooling only version, this technology will surely be
enlarged shortly to reversible applications.
Floating high pressure
LENNOX optimizes the performance of the NEOSYS chillers with
electronic expansion valve (as an option) and variable speed
ventilation (as standard) to achieve maximum energy savings.
We define a condensation temperature depending on the outside
air temperature at an optimum value to obtain the lowest power
inputs of couples, compressors and condenser fan motors.
