  • format_align_leftDescription
    Outdoor unit for the production of chilled water with semi-hermetic variable-speed screw compressors optimized for HFO R1234ze refrigerant, axial-flow fans, micro-channel full-aluminum condensing coils, single-pass shell and tubes evaporator designed by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. and electronic expansion valve. Base and supporting structure and panels are of galvanized epoxy powder coated steel with increased thickness. Eurovent certification. The screw compressors feature the variable speed technology thanks to the integrated refrigerant cooled inverter, for the maximum compactness and operating flexibility. Moreover, they feature the Variable Vi (compression ratio) technology, to change the internal geometry according to the operating conditions. Thanks to the accurate sizing of all internal components and the use of variable speed technology, the unit ensures flexibility, reliability and maximum efficiency in every operating condition.

    Versions

    • A - High efficiency
    • SL-A - Super low noise, high efficiency

    Configurations

    • - - Basic function
    • D - Partial condensing heat recovery function

    Features

    • HFO REFRIGERANT
      4th generation refrigerant HFO 1234ze, with negligible greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of HFO 1234ze < 1, GWP of R134a = 1300 as per IPCCrev. 5th) and zero impact on the ozone layer.
    • 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.
    • ErP COMPLIANT 2021
      Thanks to the inverter technology and the accurate design, the units already comply and exceed the minimum seasonal energy efficiency requirements that will start from 2021, imposed by the eco-sustainable design Directive 2009/125/EC.
    • REFRIGERANT LEAK DETECTOR
      It is supplied factory mounted inside each compressor enclosure and wired in the electrical board. In case of leak detection it will raise an alarm.
    • WIDE OPERATING RANGE
      The accurate condensation control (EC fans as standard on every model), the availability of devoted kits and smart control logics allow unit's operation from -15°C up to 55°C of outdoor air temperature and up to 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 the different installation requirements.
    • ADAPTABILITY
      Adaptability at the building’s heating request thanks to the continuous capacity regulation, assured by sophisticated control’s logic.
    • HARMONY BETWEEN UNIT AND PLANT
      Low inrush current and power factor higher than similar fixed speed units, permit an easy electrical installation which is not stressed during start-up and with no need of extra devices for power factor correction. The use of VSD technology allows the unit to partialize in a stepless way, with consequent lower fluctuations of leaving water temperature.

    Accessories

    • Noise reducer (only on not silenced versions)
    • Microchannel coils with e-coating protection
    • Traditional coils with copper tubes and alluminium fins, also available with prepainted fins or Fin Guard Silver protective treatment.
    • Kit HT to increase the unit operating range
    • Hydronic group
    • VPF (Variable Primary Flow) system
    • Set-up for remote connectivity with ModBus, Mitsubishi M-Net, Echelon, Bacnet, Bacnet over-IP.
  • keyboard_hideContrôles

    Control

    • W3000TE
      W3000TE control is available with the new KIPlink user interface. Based on WiFi technology, it 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 the status of the various components and display / reset the alarms. As alternatives, the Touch interface, with a 7” WVGA colour display and USB port, or the Large keyboard, with a wide LCD display and led icons, are available. Temperature control characterized by the continuous capacity modulation, based on PID algorithms with dynamic neutral zone related to the leaving water temperature. Complete alarm management system is available, with the “black-box” and the alarm history display functions.Consumption metering and performance measurement are possible and supervision can be developed via proprietary devices or the integration in third party systems by means of the most common protocols ModBus, Bacnet, Bacnet-over-IP, LonWorks. Compatibility with remote keyboard (up to 8 units). The programmable timer manages a weekly schedule organized into time bands (up to 10 daily time bands associated with different operating set points) to optimise unit performance by minimising power consumption during periods of inactivity. As an option (VPF package), the capacity modulation is integrated with the modulation of the water flow, by means of inverter and dedicated resources for the hydraulic circuit.
