The components are made in accordance with the companys internal technical the years, and in total conformity with UNI EN ISO 9001:2000 rules. Certification according to UNI EN 1886 (Ventilation for buildings - Air Handling Units - Mechanical requirements for units, components and sections) The UNI EN 1886 specifies methods, test requirements and classifications for Air Handling Units that apply to both the full and to the separate sections. Standard covers the following structure

aspects of the air treatment units: mechanical strength of the structure, air leakage through the casing, air leakage through filters, thermal and acoustic performance The Air Handling Unit have been tested by CONSORZIO MIP - Politecnico di Milano, which has also used the laboratories of fluid dynamics, thermodynamics and acoustics of the Faculty of Engineering at the University Politecnica delle Marche and certified the membership of the air handling units to following performance - Mechanical strength of housing: units with polyurethane foam panels of thickness 25 mm and 54 mm were found in Class 2A (best benefits provided by the standard) in both the test in positive and negative pressure.Hygienic Plus Air Handling UnitSelf-Desinfecting Air Handling Unit Hygienic Plus An arbitrarily configured Troges air handling unit in hygiene design is additionally equipped with an “Active Disinfection Module”, complete control system and all safety equipment.

The “Active Disinfection Module“ produces reactive gas mixture which is extremely reactive and oxidizes up to 99.99% of all organic substances situated in the air handling unit, such as bacteria, germs, viruses, spores and other microorga-nisms The result, even in the narrowest of cracks, are up to 99.99% disinfected and sterilized internal surfaces of the entire air handling unit and all components situated in it. outside heating/air conditioning unitsThe “Active Disinfection Module” functions with no chemicals, completely naturally and environmentally friendly. top central air conditioner brands canadaAll residues are 100% biologically degradable.ac/heater units for saleDownloadsProductinfo [715,9 KB]Wir sind gerne für Sie da:troges@troges.at> Zum KontaktformularAlle ProdukteAir Handling UnitsAirtreatment-Systems     Compact Air Cleaner     Luftbehandlungsgenerator TOGCommercial kitchen hoodsCompact Ventilation Devices     Kompaktlüftungsgeräteserie TKDuct CleaningEFG - Dehumidification Units     EFG     EFG - UEntrauchungskanalFire dampers / Smoke exhaust dampers     Fire dampers     Multiblade fire dampersFlexible pipesFlow rate controllersFresh Air ScreenHygienic Plus Air Handling UnitKitchen Exhaust Ceiling System GastroKitchen Exhaust Ceiling System PagulaLouvres and dampersLuftauslässe / KlappenRohrventilatorenRoof fan RFSchalldämmgehäuseSilencers     Duct Silencers     Flexible Sound Attenuators     Pipe Sound Attenuators     Pipe Silencing Cores     Z-SchalldämpferSmoke Exhaust Fans / Fans     Smoke Exhaust

An air handling unit is a factory-made case assembly consisting of a fan or fans and other necessary equipment to perform one or more of the functions of circulating, cleaning, heating, cooling, humidifying, dehumidifying and mixing of air. Small air handlers for local use, are called terminal units. The air handler us normally constructed around a framing system with metal infill panels as required to suit the configuration of the components.

The AHU is used to control the following parameters of the space. There are basically two types of air handling unit that are used;  In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network. In this case, the section before the fan has negative pressure. In the Blow-Through type, the fan blows the air through the mixing box, filters and cooling coil before discharging them to the space being conditioned or the ducting system. In air handling units, centrifugal fans are used to circulate the air to the various parts of the sections in the building. The selection of the fan will depend on the air volume and the static pressure required of the system. Usually, the designer of the system will use a specialised software to do this selection. In order to reduce the effect of vibration on the panel, the motor and the fan are usually installed on the vibration isolator except when the drive assembly is external to the fan casing.

The use of variable air volume (VAV) systems is becoming more popular as the volume of the air being discharged can be varied depending on the load condition. If the load is high, the fan speed will be higher and if the load is lower, the speed of the fan will be lower. The speed of the fan is varied using a frequency inverter instead of a conventional motor. A whole range of fan speed from super low to super high can now be utilised based on the load conditions required, therefore a frequency inverter can provide better control of the fan speed. A greater focus on the development in EC technology has enabled better use of energy and is in line with the move to more energy efficient products (ERP). The requirements on a ventilation system are not always the same. In many applications, all that is required is a straightforward exchange of air, whereas in other applications the requirements can vary according to the temperature, humidity and purity of the air. Noise is also a significant factor to consider when choosing AHU fan components.

Axair Fans can supply components for efficient air movement within air handling units including backward curved impellers, EC forward curved centrifugal fans and belt driven options where required. Our high performance centrifugal impeller without spiral housing, the E-Series “REVOLUTION” is a range specifically designed for volume flow. Manufactured from aluminium, the E range is designed and manufactured especially for the use of larger volume flow and lower pressure coupled with superior noise reduction and quiet operation. The impellers are manufactured using a black, UV-stabilised, long glass-fibre reinforced polypropylene. Weighing 1.22 kg/m³, the impellers are extremely lightweight when compared with aluminium or steel alternatives. Therefore, the mass of inertia and start-up resistance is minimal. With improved dirt resistance, In-balance during operation is effectively eliminated. When used with an Electronically Commutated Motor (EC-Motor) or an AC-External Rotor Motor, Axair centrifugal fans with reduced noise, free-running, backward curved, high performance impellers make a very compact, efficient and optimally designed fan unit.
