Structural requirements & standards compliance
Designed for the most demanding environments, the AHU design adheres to the highest manufacturing standards.
Energy performance
& EC motor
EC fans: high efficiency and reduced consumption
Overconsumption of electricity is reduced thanks to EC fan technology, which adjusts their speed to the required flow rate. This technology allows up to 30 % in energy savings compared to asynchronous motors, while guaranteeing high and stable aerodynamic performance.
Reliability and performance of air management
The onboard control system continuously ensures control of flow rates, temperature, humidity and pressure.
Reduced mode
Programming of standby mode based on day and time for optimized consumption management.
Heat exchangers
Heat exchangers are selected according to the facility's requirements and the constraints of the environment to be treated. The design takes into account air speed and expected performance to ensure stable temperature and humidity regulation. Anti-corrosion protection can be integrated to guarantee the durability of the equipment in demanding environments.
Constant flow regulation
The fan self-regulates to maintain a constant airflow by adapting to pressure losses.
Adapted for risks
healthcare facilities
Very high infectious risk - Risk 4
Areas with very high infectious risk require centralised air treatment with reinforced filtration and precise control of airflows, in order to limit airborne contamination.
Areas of application
Orthopaedics ward, organ transplant ward, major burns unit, protected units room (haematology), cytostatic reconstitution, parenteral solution manufacturing.
Equipment method
High infectious risks – Risk 3
Areas with a high infectious risk require enhanced air treatment, ensuring strict control of flows, pressures, and filtration to limit the spread of pathogens and protect occupants.
Areas of application
Multi-purpose room, ENT/Ophthalmology and other orthopaedics, digestive and visceral surgery room, urology, cardiovascular surgery room, neurosurgery room,...
Equipment method
Moderate infectious risks - Risk 2
Moderately infectious risk areas require air treatment to control airborne contamination while ensuring the comfort and safety of patients and staff. Managing airflow, filtration, and air currents helps to limit the spread of infectious agents.

Ease of integration
Our A2I air handling unit range is easily integrated near the areas to be treated or cleanrooms.
Optimised consumption
The energy performance of our AHU has a direct impact on consumption optimisation.
Our air handling units are designed and manufactured specifically for controlling temperature, humidity, and pressure conditions in rooms where the control of biocontamination is mandatory.
They are designed to be installed in controlled environments subject to hygiene standards such as NFS 90-351 and ISO 14644. Furthermore, in order to comply with the EN 1886 standard, it is important to respect certain manufacturing criteria such as mechanical strength, air tightness of the unit (as well as thermal bridges), thermal transmittance, filter bypass leakage, and the acoustic attenuation of the casing. As such, our air handling units possess state-of-the-art equipment to ensure compliance.
They simplify the design of air, hydraulic, and refrigeration networks thanks to design flexibility. The configuration of our air handling units allows for installation in confined spaces while also reducing manufacturing costs and time.
To the same extent as our Air Handling Unit and our Laminar air flow ceiling for operating theatre, the energy performance of our AHU has a direct impact on consumption optimisation, and therefore, on long-term energy savings. The equipment also allows for better environmental compliance with the use of refrigerants that have no harmful effect on the ozone layer (direct expansion exchanger). Finally, for an HQE (High Environmental Quality) type building, our air handling units integrate perfectly.
The fans in our AHU are equipped with EC (Electronically Commutated) motors with built-in anti-failure features, also including individual integrated electronic circuits, self-regulating motors, and internal protection.
Frequently asked questions
The air handling unit
This equipment ensures the regulation of numerous decisive parameters in air management: temperature, humidity, differential pressures, and particle air quality.
This type of equipment is intended for installations where the control of infectious or risk is a regulatory and operational requirement.
In these applications, compliance with standards and operational safety are essential and determine the type of air treatment equipment.
In healthcare facilities, air handling units play a role in meeting the requirements of standard NF S 90-351 concerning risk levels (ISO 5 to ISO 8).
The casing design allows for high performance levels to be achieved according to EN 1886:
- Mechanical deformation class D1,
- Waterproofing class L2,
- Control of F9 filter bypass leaks,
- T2 / TB2 thermal classes.
Regulatory compliance is a determining factor in the choice of equipment.
Possible configurations include single flow, double flow, and double flow with energy recovery, which are highly effective for achieving ambitious energy performance.
Also, the AHU can function as:
- Full fresh air,
- Total recycling,
- Recirculated air / fresh air.
The sizing depends on the risk level, the required mixing rate, and the architectural constraints of the building.
Integration into HQE-type projects is part of a global building performance strategy. However, energy management must not compromise health and regulatory requirements.
- Aluminium profile frame with thermal breaks
- Painted electro-galvanised steel double-skin panels
- Thermal and sound insulation in rock wool.,
- Removable access panels for ease of maintenance.,
- Condensate tray compliant with NF S 90-351 requirements.
Manufacturing quality determines the longevity of operational performance.
- No need to install heating element,
