Features And Benefi Ts - Lennox NEOSYS NAC 200 Application Manual

FEATURES AND BENEFITS
Flat top and low profi le 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 fl at 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 confi rm 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 effi ciency version,
a low noise or an ultra low noise version. NEOSYS can adapt all
situations with only one version. NEOSYS is fi tted 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 fl ow – 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.
