Heat pumps
Air to water reversible heat pumps
Reversible heat pump, air source for outdoor installation 4,20-12,4 kW
Series
i-BX-N 004 - 013

Outdoor unit for the production of chilled/hot water with variable speed (Inverter Driven) Scroll compressors, optimized for R410A in a
single-circuit configuration, axial-flow fans, condensing coil with copper tubes and aluminum fins, plate heat exchanger on water side and
electronic expansion valve as standard equipment.

Flexible and reliable unit; it easily adapts itself to different thermal load conditions thanks to the precise temperature control together with the
use of inverter technology. The high performance’s level, both full and partial load, is achieved thanks to the accurate unit’s design and to the
use of variable speed (inverter) motor.

The i-BX-N heat pumps provide for heating, cooling and domestic hot water production. Particular care is taken for winter mode, that thanks to
the Inverter technology is guaranteed beyond traditional units working limits.

Controls

NADISYSTEM
The keypad features function controls and a complete LCD display for viewing data and activating the unit, via a multilevel menu.

The remote keyboard kit wired indoor and outdoor temperature sensors allow dynamic control of delivery temperature water, optimizing comfort in the room and increasing the energy efficiency.

The electronic board allows you to manage:

  • wired remote keypad, backlit display complete with remote temperature
  • outdoor air temperature sensor on board for climatic curve
  • one zone with mixing valve for floor heating and one zone of direct heating for radiator, floor heating or fan coil
  • domestic hot water production by external three-way valve (accessory)
  • electric heater for possible integration and anti-legionella cycle for DHW tank
  • gas boiler or electric heater in substitution or in addition for space heating
  • the built-in clock can be used to create an operating profile containing time bands for space heating/cooling and for DHW
  • night mode to limit the noise level of the units. Noise level is reduced limiting the maximum speed of the compressor and fans.
  • up to 4 heat pump in cascade (with the accessories N-CM)

The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows
to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
 

Features

Characteristics

VERSION
-        Basic

ErP READY

The highest level of efficiency at part load can meet and exceed the minimum seasonal efficiency for heating, SCOP according with the eco-sustainable design requirements for all products using energy.

SYSTEM EFFICIENCY

The unit is designed as a system: all components are regulated using proprietary control’s logic for the highest efficiency.

HIGH EFFICIENCY AT PARTIAL LOAD

High seasonal efficiency in both heating and cooling mode, using DC inverter technology to modulate compressor operation and deliver the exact amount of energy based on the actual needs of the building. High efficiency for low energy consumption during the operating hours.

HIGH EFFICIENCY COMPONENTS

In terms of improving performance and reducing power consumption, the electronic thermostatic valve is an important component that maximises system efficiency, same for the choise the hydronic kit with inverter water pump and the modulating the fans speed as
standard equipments.

EXTENSIVE OPERATING LIMITS

Particular care is taken for winter mode, that thanks to inverter technology is guaranteed beyond traditional units working limits, supplying hot water up to 60°C and down to -20°external air.

INTEGRATED HYDRONIC MODULE

The integrated hydronic include all the water circuit components (anti-freeze electrical heater on plate heat exchanger, air vents, flow switch, water filter, safety valve, EC water pumps, expansion tank) so as to optimize installation space, times and costs.
