Compact air-air rooftop units
There are 3 optional fans depending on the available pressure: • Low pressure (L): all models except for 0280 and 0320. • Nominal pressure (N): all models. • High pressure (H): models 0200 to 0380. Important: our “Selection Software” will choose the supply fan with lower consumption for the available pressure required.
Rotary heat exchanger in a module integrated into the unit (assemblies CW and TW). This heat recovery unit is used to transfer the sensible and latent heat from the air-conditioned room’s return air to the fresh air used for ventilation, before it is discharged outdoors. This option reduces the compressor runtime, ensuring energy savings and benefiting the environment. The efficiency of energy recovery depends on the wheel selected: material, dimensions, channel spacing and type of speed control.
Options to improve indoor air quality: Gravimetric filters G4 with low pressure drop. Gravimetric filters G4 + folded opacimetric filters F6 to F9. Gravimetric filters G4 with low pressure drop + folded opacimetric filters F7 and F9 with low pressure drop. Double stage of folded opacimetric filters (F6+F7; F6+F8; F6+F9; F7+F8; F7+F9; F8+F9). Stop-drop in the indoor air coil. Recommended in cases where a high moisture content in the air is foreseen or when the air flow is high. Note: with hot water coil it is not possible to assemble the stop-drop.
Axial 2-speed outdoor fan(s) directly coupled to the motor. Watertight motor class F, IP54 and internal thermal protection. Dynamically balanced propellers and outdoor protective grille. Ambient temperature sensor. There are 2 options: Ceramic fibre for thermal and acoustic insulation, with fire classification Euroclass A2-s1, d0 (M0). Note: panels and registers of the indoor unit always include thermal and acoustic insulation, with fire classification Euroclass A2-s1, d0 (M0). • One NTC sensor connected to the control board. Note: An ambient sensor with RS485 communication is required for installation at more than 30 m. • One to four sensors with RS485 communication. Ambient temperatute + humidity sensor with RS485 communication (compulsory in units with optional enthalpic or thermoenthalpic free-cooling). In this case, the outdoor air humidity sensor is also added.
Condensate drain pan in stainless steel for corrosion protection. Control of the overpressure. In installations with different air flow in supply and return, to prevent the entry of outside air or to eliminate odors from inside, the outdoor damper and the extraction damper will be managed independently. Differential pressostat for the detection of clogged filters as safety protection. Air quality sensor to enable measuring CO2 There are 3 options: Outdoor coil protective grille. Stop-drop at the fresh air intake. Recommended in cases where a high moisture content in the air is foreseen. Antivibration mounts made of rubber. Maritime packing SEI4C. • Sensor for installation environment. • Sensor duct-mounted picture), in the
• Sensor installed on another unit of the local network (pLAN). Smoke detecting sensor. Smoke detecting station in accordance with the NF S 61-961 standard.
