i-NX 0151P - 0502P
Outdoor unit for the production of chilled water with fixed and variable speed (Inverter Driven) Scroll compressors, optimized for R410A in a single-circuit configuration, axial-flow fans, micro-channel full-aluminum air coils, and electronic expansion valve as standard.
Flexible and reliable unit; it easily adapts to different thermal load conditions thanks to the precise temperature control together with the use of inverter technology. The high performance levels, both at full and partial loads, is achieved thanks to the unit's accurate design and to the use of a fixed speed motor together with a variable speed (inverter) motor.

Features
HIGH EFFICIENCY
Unit with high efficiency and reduced energy consumption, thanks to the inverter technology which contributes to lower operating costs and therefore a quick return on investment.
ErP READY
Thanks to the inverter technology, the high level of efficiency at part loads meets and exceeds the minimum seasonal efficiency required by the Ecodesign Directive starting from 2021.
VARIABLE PRIMARY FLOW
Energy savings due to variable pump speed management based on load demand and the variable flow ensures the units also function in critical working conditions.
INTEGRATED HYDRONIC MODULE
The built-in hydronic module already contains the main water circuit components; it is available as option with single or twin in-line pump, for achieving low or high head, fixed or variable speed and buffer tank.
ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS
This new chiller range uses aluminum micro-channel condensers that ensure a premium level of efficiency. This solution also reduces the refrigerant charge with respect to traditional copper/aluminium coils and reduces the weight of the unit.
WIDE OPERATING RANGE
Full load operation is ensured with outdoor air temperatures up to 48°C during summer. Dedicated accessories allow the unit to operate in outdoor air temperatures down to -20°C during winter.
Production of evaporator leaving water temperatures from -10°C to 20°C.

Electronic control W3000TE
W3000TE Compact features function controls and LCD display for viewing data and activating the unit, via a multilevel menu, with settable display language. As alternative, the innovative KIPlink user interface allows one to operate on the unit directly from the smartphone or tablet. The controller provides water temperature control for the heating systems, cooling systems (only for reversible units), as well as for domestic hot water (only for reversible units). These different temperatures are managed automatically based on the different conditions in which the system operates, with the possibility to assign specific levels of priority to domestic hot water production, depending on the needs of the application. Regulation based on the exclusive QuickMind algorithm, including self-adaptive control logics, beneficial in low water content systems. As alternatives, the proportional- or proportional- integral regulations are also available. Complete alarm management system is available, with the “black-box” and the alarm history display functions.
For multiple unit systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. Built-in clock can create an operating profile containing up to 4 typical days and 10 time bands, essential for efficient programming of energy production and fundamental for managing the Legionella prevention cycles. Supervision is available either using proprietary devices or by integration into third party systems using ModBus, BACnet, BACnet-over-IP and Echelon LonWorks protocols. A dedicated wall-mounted keypad can be used for remote control of all the functions.
Optionally (VPF package), capacity modulation can be integrated with hydraulic flow modulation, thanks to inverter-driven pumps and to specific resources for the hydraulic circuit.
