NX2-FC-G06 0384 - 0926
Outdoor unit for the production of high temperature chilled water equipped with scroll compressors, R454B refrigerant, axial-fans, micro-channel full-aluminum condensing coils, shell and tube evaporator, and electronic expansion valves. Base, supporting structure, and panels are of galvanized epoxy powder coated steel. The free-cooling system chills the water exploiting the outdoor air cold temperatures. It consists of additional water coils, made of copper tubes and aluminum fins, and a devoted hydraulic valve system.
The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

Features
LOW GWP REFRIGERANT
The new generation refrigerant R454B is the most eco-sustainable alternative to traditional refrigerant R410A, offering a 76% reduction in terms of GWP (Global Warming Potential GWP of R454B = 467, GWP of R410A = 1924 as per IPCC rev. 5th) and zero impact on the ozone layer.
FREE-COOLING
The generous size of the free-cooling coils allows to produce the nominal cooling capacity without the use of the compressors for many hours per year, thus cutting the annual energy consuption.
ELECTRICAL AND THERMAL METERING
Functions and kits for the smart metering of the electrical power consumption and the cooling capacity produced.
GROUP CONTROLS WITH DYNAMIC MASTER
Load sharing, sequencing, active redundancy, priority of resource activation, alarm management, theese are only some of the LAN functions that the unit is able to manage when connected to a group of chillers. Besides, the system's stability is ensured even in case of alarm or malfunctioning thanks to the Dynamic Master logic.
INTEGRATED HYDRONIC GROUP
The optional built-in hydronic module already contains the main water circuit components; available with single or twin in-line, for achieving both low or high head.
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.

Electronic control W3000+
W3000+ features an easy-to-use interface and a complete LCD display that allows one to consult and intervene by means of a multi-language menu (19 languages are available). The diagnostics includes a complete alarm management, with the “black-box” and the alarm history display for enhanced analysis of the unit operation. The programmable timer manages a weekly schedule organized into time bands to optimize unit performance by minimizing power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. As option, KIPlink is available - Keyboard In Your Pocket. KIPlink is the innovative user interface built on a web-based architecture, enabling direct interaction with the unit through a browser-based interface. The regulation features the continuous modulation of capacity, based on sequential adjustment + DIP referring to the leaving water temperature.
Optional proprietary devices can perform the adjustment of resources in systems made of several units. Consumption metering and performance measurement are possible as well. The variable primary flow control is always available as per standard (VPF.E function). Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet-over-IP, Bacnet MS/TP RS485, Konnex, ModBus TCP/IP, SNMP. Compatibility with the remote keyboard (up to 8 units).
