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
Accessories
- Noise reducer (only on not silenced
versions) - EC fans with electronic DC brushless
motor (for K 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. - Leak detector
- 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.
