  • DC Inverter Outdoor units for 3-way MULTISET VRF systems
  • Wide operating range: up to -20°C
    in heating mode, -10°C in cooling mod
  • Twin Rotary DC Inverter Compressor
    + Scroll compressor
  • Low sound level
  • Maximum total pipe lenght: 300m
  • "Long Life" and "Fault-Tolerant"
    special control systems
  • DC Inverter Outdoor units for 3-way MULTISET VRF systems
  • Automatic change-over between cooling and heating modes for each indoor unit; this feature, based on the three-way technology with heat recovery, allows a fully independent operation of each indoor unit.
  • R410A HFC refrigerant.
  • Twin Rotary DC Inverter compressor, highly efficient at low rotation frequencies, matching with a Scroll Constant-Speed compressor.
  • Fan with direct current motor that allows a consumption reduction of about 50% and a speed modulation up to 16 steps in spite of the usual 4 steps of the alternate current motors; this performance increases the efficiency of the thermodynamic system which is able to best adapt to the variations of temperature and thermal load of the rooms .
  • The use of a special oil sensor allows, for the first time in the world, to keep under control the lubrification of the mechanical parts of the compressor.
  • Special air intakes and Double Chamber construction technology allowed to unify the dimensions of the units, making easy the closing up for multiple installatios in which two units can be placed at a distance of only 10 cm one from the other, the smaller distance available.
  • Low sound level thanks to a special fan made of resin and a particular resin grille, designed and used for these units in order to minimize air pressure drops.
  • New high efficiency Cross-Arranged heat exchanger with three-way suction, divided in two sections with double control of defrosting cycle.
  • Pressure control automatic and by software on PC.
  • Pipe connession inside the unit frame through a special space to be closed back when the installation is finished.
  • Equipped with "Fault-Tolerant" system granting in multiple installations the operation of the air conditioning system also in case of total stop of one condensing unit.
  • Support to "Long-Life" system that, in multiple installations, allows a cyclic use of the condensing units, granting a balance of the compressors activity.
  • "On Demand" feature allows to best use the characteristics of DC Inverter technology, setting three different levels of electric power on which are automatically based the control microprocessors so that to achieve the maximum performances with reduction of electric consumption.
  • Wide range of outdoor air temperature :
    Outdoor temperature: from  – 10° C to + 43° C in cooling mode
    Outdoor temperature: from  – 20° C to + 15° C in heating mode.
  • Maximum lenght of the refrigerant circuit extended to 300 m.
  • The refrigerant circuit doesn't require distribution apparatus downstream of the unit as it can be realized with a tree structure using only the special distributor accessories; this feature facilitates any type of system widening, by adding both outdoor and indoor units.
  • Three-phase autosense power supply 380-415/3N/50Hz.
