• 1-air volume : models 90 to 180
• 2-air volumes : models 240 to 360
■■
Outdoor circuit --
Electronic EC axial fan ( s ) that adapt the rotation speed to the installation requirements , thereby reducing electricity consumption , the sound level at partial charge and improving the average seasonal output of the unit .
-- Coil with copper pipes and aluminium fins .
AIR TREATMENT
■■
Indoor circuit --
Electronic plug-fans directly coupled with variable speed and flow sensor . Facilities type of service industries consumption of fans associated with air transportation assumes a high % of the annual consumption of air conditioning . The use of fans of greater efficiency has a direct impact on the reduction of consumption .
