POMPE DE CALDURA, AER CONDITIONAT, CHILLER

Residential chillers and heat pumps

Climaveneta > Commercial and industrial chillers

FX 1502 – 7223

Chiller, air source for outdoor installation
Cooling capacity 289 – 1710 kW

NECS 0202T - 0612T
Outdoor unit for the production of chilled water with semi-hermetic screw compressors optimized for R134a, axial-flow fans, micro-channel full-aluminum condensing coils, single step shell and tubes evaporator designed by Climaveneta and electronic expansion valve. Base and supporting structure and panels are of galvanized epoxy powder coated steel with increased thickness. Eurovent certification. Flexible and reliable unit; it easily adapts itself to different thermal load conditions thanks to the precise thermoregulation and the accurate sizing of all internal components. The compressors feature an enhanced lubrication system, an innovative internal geometry and a different control of capacity steps. Innovations that grant a remarkable performance improvement especially at partial loads.

Features

  • HIGH EFFICIENCY
    Very high efficiency at full and partial load, at the highest market levels, thanks to the adopted technological solutions. These units ensure low operating costs and therefore a quick payback time.
  • EXTREMELY SILENT OPERATION
    As the result of a systematic design oriented to minimize the noise level, the silenced version units give the best combination of quietness and efficiency on the market.
  • FLEXIBILITY
    Flexibility in the applications thanks to the many configurations and versions available.
  • WIDE OPERATING RANGE
    The accurate condensation control (variable fan speed regulation as per standard on every model) and devoted kits allow unit’s operation from -10°C (option -20°C) to 46°C (option 50°C) of outdoor air temperature and from -8°C to 18°C (option 20°C) of evaporator leaving water temperature. 
  • ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS
    The full aluminium micro-channel condenser coils deliver high efficiency whilst ensuring a reduced refrigerant volume and a lower unit weight. The e-coating protection (optional) grants the highest level of resistance to corrosion in any condition, even in the most aggressive environments.
  • INTEGRATED HYDRONIC GROUP
    The built-in hydronic group (optional) includes the main water circuit components. The 2 pumps are in twin configuration and available with 2 or 4-pole motor, fixed or variable speed, high or low head to satisfy all the different industrial and comfort application requirements.

Controls

  • W3000TE
    The W3000TE controller offers advanced functions and algorithms. KIPlink – Keyboard In Your Pocket – is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the 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 in detail the status of the refrigerant circuits, the compressors, the fans and the pumps (if present) and display and reset the possible alarms. In addition to or as an alternative, the Touch interface, with a 7” WVGA colour display and a front USB port, or the Large keyboard, with a wide LCD display and led icons, are available. The temperature control is characterized by the continuous capacity modulation, based on PID algorithms and related to the leaving water temperature, with adjustment on the neutral areas. The diagnostics comprises a complete alarm management system, with the “black-box” (via PC) and the alarm history display (via user interface or also PC) for enhanced analysis of the unit operation. Optional proprietary devices can perform the adjustment of the resources in systems made of several units. Consumption metering and performance measurement are possible as well. 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, Bacnet-over-IP, LonWorks. Compatibility with the remote keyboard (up to 8 units). The programmable timer manages a weekly schedule organised into time bands to optimise unit performance by minimising power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points.
