Casing - Casing made of galvanised steel metal with polyester paint, white colour RAL 7035. Thermal insulation 9 mm thick, with fire classification M1. - Self-supporting frame and access panels to the electric panel, compressors, fans, etc. 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. 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. - Reusable air filters, assembled on a frame. - Coil with copper pipes and aluminium fins. - Condensates drain pan. - Thermostatic expansion valve(s) with external equalisation. Cooling circuit - Hermetic scroll-type compressor in tandem design that improves the management of stages. Sound insulation, assembled over antivibration mounts. Control of phase equilibrium and the direction of rotation. Crankcase heaters. - Four-way cycle reversing valves (heat pump units). - Anti-acid dehydrating filter(s). 822
