Outdoor unit for the production of chilled water with
semi-hermetic variable-speed screw compressors
optimized for R134a, 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.

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.
    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.
  • WIDE OPERATING RANGE
    The accurate condensation control (variable fan speed regulation as per
    standard on every model), the availability of devoted kits and smart control
    logics allow unit’s operation from -20°C up to 55°C of outdoor air temperature
    and from -8°C to 20°C of evaporator leaving water temperature.
  • REDUCED FOOTPRINT
    These new units have a reduced footprint, making them the best solution both
    for new plants (thanks to high efficiency) and for the replacement of obsolete
    units in existing plants, offering a very high efficiency increase with same
    dimensions and cooling capacity.
  • 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
