RG66012163 - Rev 00
PERFORMA (MPE) water chillers and heat pumps are designed for outdoor
installation in both residential and industrial applications�
The range uses R410A refrigerant, which assures high levels of performance
with relatively low energy consumption and features 19 models in the chiller
and heat pump version, with cooling capacities ranging from 7 to 66 kW and
heating capacities from 8 to 75 kW�
BEYOND CONVENTIONAL WORKING LIMITS
The finned block heat exchangers have been optimised for R410A and use 8
mm copper pipes, which permit a better heat exchange and quiet operation
of the fans�
Their generous sizing guarantees the production of chilled water even with
outdoor air temperatures as high as 51°C and all models of the range assure
an average energy efficiency ratio (EER) of 2�95 in the cooling mode and
heating efficiency (COP) of 3�25, corresponding to the Eurovent Energy
Efficiency Class A
EFFICIENCY IN ALL CONDITIONS
The actual thermal load of an air conditioning system is less than 60% of the
rated load capacity 90% of the time; the MPE T version with single-circuit
dual compressor answers this demand by offering high efficiency during
operation under partial load conditions (ESEER>4) and also guarantees the
unit’s operation at the worst temperature conditions�
In such conditions the microprocessor controller activates the capacity control
mode, doubling the condensing surface available to the single compressor�
The axial-type fans with airfoil-shaped blades and 6- and 8-pole motors with
electronic speed control (optional) guarantee quiet operation and optimal
performance of the unit in all conditions�

SELF-ADAPTIVE
The electronic control system allows the setpoint to be adjusted automatically
according to the outdoor temperature in order to reduce consumption and
broaden the working temperature range�
The unit can also function in systems with a low water content, even without
the use of a storage reservoir, thanks to the automatic adjustment which
limits the number of compressor starts and thus extends the life of the
compressors themselves

SMART DEFROST SYSTEM
The exclusive defrost system (optional feature available with the advanced
controller) can correctly identify an impairment of performance in the outdoor
exchanger due to the formation of ice and minimise the process time in
relation to normal operation of the unit�

RADIAL FANS
The impellers are made in a single piece with an alloy of special materials
developed so as to ensure high rotational speeds, and thus a high power
density of the fan� The impellers’ design was developed using complex
simulation models optimized through experimental tests performed on
prototypes� The result is a uniform air flow over the impeller’s entire cross
section, in order to guarantee very low pressure loss� A uniform air flow
profile also results in fewer noise sources and, therefore, extremely low
noise levels during operation�
The MPE DUCTED radial fans can be equipped with a permanent magnet
(brushless) electric motor, controlled by an inverter, which enables continuous
adjustment in the number of fan revolutions�
The great advantage of brushless motors is the significant reduction in
power consumption, which in instant operations reaches up to 1/3 of that
of conventional motors and at around 50% in integrated operations, with a
corresponding reduction in CO2 emissions!
