NX-CN 0072 - 1104

Reversible unit, air source for indoor installation 18 - 265 kW

Heat pump for indoor installation to produce chilled/hot water with hermetic rotary Scroll compressors, centrifugal plug fans with EC motor, braze-welded plate-type exchanger and thermal expansion valve. Structure and the external paneling made from hot-galvanised metal plate and painted with epoxy powder coat RAL 7035. The panels are easy to remove for quick and easy access to internal components from either side of the unit. The range includes the single-circuit two-compressor versions and the dual circuit four-compressor versions.

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.

ErP READY

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

PLUG FUN WITH EC MOTOR

More air flow with a smaller diameter. Energy cost savings with the highest efficiency at the operating point. Fans are directly coupled with the motor, no energy lost due to transmission (belts and pulleys). External rotor fitted with permanent magnets. Outstanding efficiency even at partial loads, due to the lack of brushes and lower consumption in every working condition in order to achieve a better seasonal efficiency in accordance with the ErP Directive.

TOTAL VERSATILITY

Horizontal or vertical air flow.

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 pumps, for achieving low or high head, with fixed or variable speed.

Electronic control W3000TE

The W3000 Compact keypad provided as standard, features control functions and a complete LCD display for viewing data and activating the unit, via a multi-language menu. In alternative or in addition to the keyboard, the innovative user interface KIPlink allows one to operate on the unit directly from a smartphone or tablet. Using KIPlink, it is possible to turn the unit on and off, adjust the set-point, plot the main operating variables, monitor the status of the refrigerant circuits, the compressors, the fans and the pumps (if present), and display and reset possible alarms. The regulation is based on the exclusive QuickMind algorithm, including self-adaptive control logics, beneficial in low water content systems. Alternatively, proportional or proportional- integral regulations are also available. A complete alarm management system is available, with a “black-box” and the alarm history display functions. For a multiple unit systems, the regulation of the resources can be implemented via optional proprietary devices. Energy metering, for both consumption and capacity, can also be developed. The built-in clock can create an operating profile up to 4 typical days and 10 time bands. 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 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.
