FEATURES AND BENEFITS
4/73
• Triple circuits
Note: Equipment contains fluorinated greenhouse gases. Actual refrigerant charge depends on the final
unit construction, details can be found on the unit labels.
Versions This range is available in two different versions:
STANDARD EFFICIENCY (
Eurovent conditions according EN14511
)
17 sizes to cover a range from 290 up to 2148 kW with an EER up to 3.04 and an ESEER up to 3.93
(data referred to Standard Noise).
HIGH EFFICIENCY (
Eurovent conditions according EN14511
)
17 sizes to cover a range from 351 up to 2087 kW with an EER up to 3.15 and an ESEER up to 4.05
(data referred to Standard Noise).
The EER (Energy Efficiency Ratio) is the ratio of the Cooling Capacity to the Power Input of the unit.
The Power Input includes: the power input for operation of the compressors, the power input of all
control and safety devices, the power input for fans.
The ESEER (European Seasonal Energy Efficiency Ratio) is a weighed formula enabling to take into
account the variation of EER with the load rate and the variation of air inlet condenser temperature.
ESEER = A x EER100% B x EER75% C x EER50% D x EER25%
K = Coefficient; T = Air inlet condenser temperature.
Sound configurations Standard, low and reduced sound configurations available as follows:
STANDARD SOUND
Condenser fan rotating at 900 rpm, rubber antivibration under compressor
LOW SOUND
Compressor fan rotating at 900 rpm, rubber antivibration under compressor and the sound attenuation is
achieved thanks to special connections at the suction of each compressor that allows to reduce drastically
the vibration transmission.
REDUCED SOUND
Compressor fan rotating at 700 rpm, rubber antivibration under compressor and the compressors are
closed into a soundproof cabinet especially designed to minimize the sound emissions. Also special
connections at the suction of each compressor allow to reduce drastically the vibration transmission.
