.
- Specifi c MCHX coil design with high mechanical fi n resistance
that offers easy cleaning with high pressure air or water washers
for extended life cycle.
- V-coil design, compressor and hydraulic enclosure to protect
the unit against climatic conditions (e.g. sun rays, UV light, hail).
- Exclusive Compliant Scroll® compressor design with both
axial and radial compliance to increase compressor operation
tolerance of liquid refrigerant or debris, substantially improving
3-year warranty*
durability and reliability.
- Exclusive fan design with SKF hybrid Ceramic bearings
to double (treble in some cases) the service life of the motors
and to reduce noise level. With these sealed hybrid ceramic
bearings, our customer can expect little or no maintenance of
the motor throughout its life.
Quiet performance
- Unique design with compressor, pump(s) and fan acoustic
enclosure to reduce radiated noise emissions.
- Inverter fans using external rotor technology associated with
high performance aluminium fan blades of the latest generation
(Owlet™ design).
- Elimination of intrusive fan start/stop noise that is irritating
to the human ear.
- Active Acoustic Attenuation System™ to meet changing
building load requirements while automatically adjusting the
air fl ow to meet night and day sound level constraints (Time
schedule with 4 time zones per day).
Quick performance and service
- Complete hydraulic module with single or twin, low or high
pressure pump (options) that includes all necessary equipment
for quick connection: pump(s), regulating valve, expansion tank
vessel with pressure gauge, pressure tapping points, water
fi lter, air vent, pressure relief valve and Victaulic connections.
- 400V, 50 Hz, 3 phase power supply (without neutral) with a
single point of power connection. Main on/off switch included
in as standard.
- Air spring powered Butterfl y electrical panel with jacks top
opening providing protection to service engineers against rain
or snow during commissioning and maintenance operations.

Energy performance
- High Energy Performance (ESEER above 4; EER up to 2.9 ;
COP up to 3,2) for improved energy consumption all around the
year.
- Aluminium micro channel heat exchanger that offers +10%
outstanding system effi ciency (cooling only version).
- R410A refrigerant for optimized system performance.
- Energy savings due to lower system minimum water content
reducing the time to reach setpoint. This can also eliminate the
need for a buffer tank.
Architectural integration
- State of the art design with hidden compressors, fans and
pump for perfect architectural integration.
- Flat top, aesthetic grilles, very low unit height (< 2 m) for
discrete installation on a roof reducing the requirement of costly
cladding solutions around the unit.
* This warranty covers parts only. The above warranty is liable if
the start-up and periodic maintenance agreement is contracted
by a LENNOX company or any company accredited by LENNOX.
Refer to LENNOX 3 year warranty conditions.
