PERFECT COMFORT
AND MAXIMUM
EFFICIENCY
Air cooled heat pump for outdoor installation,
from 4,16 to 34,3 kW
Outdoor unit for the production of chilled / heated water
with rotary hermetic compressors with variable speed
(Inverter Driven) in a mono-circuit configuration, using
R410A refrigerant, air side exchange coil with copper
pipes and aluminum fins, water side brazed plate heat
exchanger and electronic expansion valve as standard.
i-BX-N adapts to the most diverse load conditions
thanks to the accurate temperature control combined
with the use of inverter technology, ensuring a high level
of energy efficiency both at full and partial loads.
THE HEAT PUMP
FOR EVERY NEED
COMFORT APPLICATIONS
System efficiency
The unit is designed with a system approach: all components
are synergistically regulated according to proprietary logic to
maximize the efficiencies of the unit.
High efficiency at partial loads
High seasonal efficiency values, thanks to the modulation of
the compressor with DC inverter technology that guarantees
the exact energy in correspondence with the real needs of the
building. High efficiency which translates into reduced energy
consumption throughout the unit’s working period.

73% of the time, the chiller works to
meet half the building’s cooling load.
In fact, only one working point is no
longer an expression of the efficiency
of the unit, the focus is on seasonal
efficiency.

energy efficiency requirements, SCOP, for both low
temperature and medium temperature applications.

SILENT
OPERATION
DOMESTIC HOT
WATER
Reduction of the sound level of
the unit, reducing the frequency
of the compressor and the fan
speed.
Production of domestic hot water guaranteed all
year. The controller manages the production of
domestic hot water through a 3-way valve to be
installed externally to the unit.
REDUCED ENERGY CONSUMPTION
EASY INSTALLATION
Dynamic control of the water supply temperature depending
on the outdoor air temperature greatly increases the comfort
and energy efficiency of the system.
The i-BX-N are packaged mono-block heat pumps
that are particularly easy to install.

The hydraulic components are all contained inside the
unit and the pipe connections are hydraulic, therefore
it is not necessary to carry out the typical procedures
of direct expansion air-conditioning systems (vacuum,
refrigerant topping up, etc.).

The auxiliary sources are activated to meet the building
needs at low external temperatures by integrating the
heating capacity of the heat pump.
The controller is able to regulate two zones both
in heating and cooling and with different delivery
temperatures, making the i-BX-N heat pump compatible
with different types of systems with different water
temperature levels.
CASCADE MANAGEMENT OF UNITS
Nadisystem is able to manage up to 4 cascade
units in master slave mode, with the master unit
taking care of processing the information and
then transmitting it to the slave units.
