Double wall insulated panels
Removable condensates drain pan
Casing made of galvanised steel metal with polyester paint, white colour RAL 7035 and graphite grey colour RAL 7024. New free-standing frame that allow the transport of two stacked units. Access panels to the electrical cabinet, compressors, fans, filters, etc.
• Greater efficiency of the motor. Permanent magnet EC motors activated using electronic switching integrated into the motor itself. • Variable speed to ensure a constant supply of air flow rate regardless of the filtre fouling level. • Accurate measurement of flow rate through a calibrated section at the fan intake and a differential pressure sensor allows the control to handle the flow rate reliably and precisely in both CAV and VAV systems. Reusable gravimetric G4 air filters, mounted on a frame. Dual locking system mounted on the access panel to filters. Removable condensates drain pan.
Coil with copper tubes and aluminium fins. EC electronic axial fan(s) which adapt their rotation speed to the installation requirements, thereby reducing electricity consumption, the sound level at partial load and improving the average seasonal output of the unit. The set of motor fan(s) may be lifted to access the inside of the outdoor unit.
Tandem hermetic scroll-type compressors which improve the management of stages. Sound insulation, fitted on antivibration mounts. Direction of rotation and phase balance control Crankcase heater. Electronic expansion valve(s). Four-way cycle reversing valve(s) (heat pump units). Acid-resistant filter dryers. Cooling design: • 1-air volume: models 0090 to 0190. • 2-air volumes: models 0200 to 0380.
Thermal and acoustic insulation, in double wall panels and registers, with fire classification Euroclass A2-s1, d0 (M0). Coil with copper pipes and aluminium fins. Supply electronic EC plug-fans directly coupled with variable speed and flow sensor. In service industry facilities, the consumption of fans associated with air transportation represents a high % of the annual consumption of air conditioning. Using fans which are more efficient has a direct impact on reducing consumption. Variable speed plug fans offer the following advantages: • Elimination of friction loss during transmission thanks to direct drive. • Greater aeraulic efficiency of the rotor (impeller jet with optimised profile), with very high available pressure.
