format_align_leftDescriptionAutonomous cooling only air-to-air Rooftop unit for outdoor installation, for the thermo-hygrometric treatment, filtration and air renovation, in medium-small surface and volume ambient (shops, bars and service areas). Units have Hermetic rotary scroll compressors in tandem with R410A refrigerant; single refrigerant circuit with electronic lamination valve; aluminium structure and coated galvanized steel base; air treatment section with sandwich panels with external surface made with coated galvanized steel RAL 7035 painted and EC plug fans. The condensing side has an EC axial fan and it’s made with hot galvanized sheet metal painted with polyester powders RAL 7035. According to the selected version, the unit allows for the management of free cooling, with motorized dampers for return, exhaust and fresh air.
- AR - Air recirculation function
- MF - Mixing and Free cooling function
- AX-F - Mixing and Free cooling and axial fan for extraction with thermodynamic heat recovery from exhaust air flow
- ENERGY EFFICENCY
The unit fulfill EU regulation 2016/2281; in particular, the unit is in line with energy efficiency limits starting from January 1st, 2021 (ErP 2021).
- HIGH RELIABILITY
The wide working range and the accurate design of the components ensure optimum performance and comfort, with a continuous and constant operation also during heavy thermoigrometric conditions.
The unit is available with the opportunity to choose different supply and return airflows directions.
- ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and different external conditions. It was introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions
- Enthalpy free-cooling
- CO2 control sensor for air quality
- High efficiency plane filters ePM01 50% (ISO16890, F7 EN779) or ePM01 80% (ISO16890, F9 EN779)
- Vair: variable air flow function, it allows to vary supply and return air flow according to the actual request of the HVAC system.
- AR - Air recirculation function
AIR3000TE is made up by two control boards, dedicated to the air side and the refrigerant side respectively. The LCD display has multi-level menu that allows for the monitoring and intervention on the unit. Thermoregulation is proportional to steps, referred to the return temperature; proportional-integral management can also be set. Its functions include the adjustment of the ambient humidity, the thermal or enthalpic (optional) free-cooling and supply temperature limitation. Defrosting is based on a self-adaptive propriety logic with monitoring of several operating and environmental parameters. The management of the ventilation can be realized with constant air flow or pressure regulation: as pressure drop varies, the fans change speed so as to maintain the flow-rate at the designed value. The controller independently manages several optional thermal resources and the amount of fresh air. The presence of the programmable timer allows the user to create an operating profile containing up to 4 typical days and 10 time bands. Diagnostics include complete alarm management, "black box" function (via PC) and alarm history (via display or even PC). Supervision can be developed via third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, ModBus-over-IP, Echelon LonWorks protocols. Compatibility with the remote keyboard managing up to 8 units.
