These products are more silent because of they are produced by using 6 poles ~ 900 rpm fan motors instead of standart series. It is a specialized series which solves high volume problems occuring in applications near to living environment. Optionally, volume can be reduced to possible lowest level by applying sound insulations. Pitch space of condensers is 2,10 mm and inner – grooved copper tubes are used.
In all series, the difference of condensation and ambient temperature (?t) is calculated as 10 ºC. Thus all products have been able to work properly even the ambient temperature is +40ºC. Whole production process is controlled with barcode system.
