NX2-W-G06 0042 – 0242
Water cooled chiller
45,8 – 242 kW
Water to water indoor unit for the production of chilled water with Scroll compressors with intermediate discharge valve (IDV), low-GWP and ozone-friendly refrigerant R454B, braze-welded plate-type exchanger and electronic expansion valve. Base and frame in hot-galvanised shaped sheet steel with a suitable thickness. All parts polyester-powder painted to assure total weather resistance, RAL 7035. The range includes the single-circuit two-compressor version.
Features
HIGH EFFICIENCY
Very high efficiency at full and partial loads, at the highest market levels, thanks to the adopted technological solutions. These units ensure low operating costs and therefore a quick payback time.
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.
SAFETY DESIGN
Family range with A2L refrigerant, completely designed to meet completely all the safety requirements for the installation inside the machinery room. Including new risk assessment evaluation strategies in accordance with the latest Directives, new design of the components inside the compressor compartment, new separated electrical panel and inclusion, as a standard, of refrigerant leak management devices (leak detector and valves) for a prompt unit power off in case of leakage.
ErP READY
The highest level of efficiency at part loads can meet and exceed the minimum seasonal efficiency for heating, SCOP (only for reversible units) and for cooling, SEER, according with the eco-sustainable design requirements for all products using energy. The units already comply with the minimum seasonal energy efficiency requirements that will start 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.
EXTREMELY SILENT OPERATION
Extremely silent operation together with high efficiency, thanks to dedicated acoustic devices and a precise design for the choice of the components.
INTEGRATED CONDENSATION CONTROL
The electronics of the units manages the most suitable condensing control for each type of application: pressure-controlled valve, two or three-way modulating valve, 0-10V signal for variable speed driven pumps.
TOTAL VERSATILITY
The units have been designed with a range of integrated accessories, keeping in mind the operation with open loop (well water or ground water), dry cooler, or cooling tower and they are suitable for geothermal application so as to satisfy all service systems and installation requirements.
ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and at different working conditions. It guarantees energy savings due to efficiency optimization in various different working conditions which translates into a reduction in operating consumption, a faster start-up of the unit and a wider extension of the operating limits.
