The luxury hotel SO PARIS is located in the MMC multipurpose building in Paris, as part of the renovation of the historic French government building. The distributor of air curtains in France, Exeltec, has carried out this project to cover the access doors to the establishment. The air curtain model chosen was Invisair, the most discreet recessed air curtain in the Airtècnics catalogue, as only the jet discharge blades are visible, made of anodized aluminium airfoil type, adjustable 15º in both directions. The rest of the unit is hidden in false ceilings, walls or false ...

In a food products company, specifically a packaging plant for ready-to-drink products, our partners from Rosenberg France and their trusted installation company, obtained a retrofit project for the renovation of the AHU. They opted for an ECFanGrid with high-performance, low-consumption fans. In this installation, they required an output of approximately 25,000 m3 of air per hour, working at 83% speed and with the possibility of increasing the flow rate by 17%, up to more than 30,000 cubic metres per hour if necessary. FLEXIBLE CONFIGURATION This project was carried out with ...

Filter stages are indispensable in ventilation equipment. They protect the equipment from external agents that may affect it or are used to prevent contaminants from entering through the ventilation ducts in places that must be sterile (operating theatres, clean rooms, etc.). Let's take a look at the types, the rules that govern them and their usual application. As they are components that are in contact with contamination and dirt, it is very important that these filters are properly maintained. Thereby, it's ensured their optimal functioning and, above all, that they are replaced ...

K7 700 HEPA OH· FC is the new generation of air and surface purification and disinfection thanks to the triple technology to improve indoor air quality. An air purification system by means of three filtration stages and a double system patented by Airtècnics of air and surfaces disinfection by means of controlled expansion of hydroxyl radicals and photocatalytic fan. The device works by recirculation and combines two types of purification technologies: active and passive, capable of acting on fine particles PM10, PM2.5 and PM1. It does not need to be connected to the ...

A ventilation retrofit project refers to the modernization or retrofitting of air handling units in ventilation and air conditioning systems with more efficient components.    Problems in AHUs are often caused by old belt-driven fans. Their inefficient motors have lower efficiency and high energy consumption. The rubber belts of the fan belts wear out over time. This wear causes dust to circulate in the ducts and can lead to poor air quality. In addition, when one of these fans fails, the ventilation system stops working, leaving the building without mechanical ...

Dam Twin is an application of the air curtains model Dam, from Airtècnics standard range. It is a double air barrier system that allows a greater efficiency in the separation of environments and it is highly recommended for installations in complex or critical conditions. The installation of two Dam air curtains one in front of the other vertically on each side of the door, is completed in a special and unique way developed by Airtècnics: the suction of one of the air curtains is in front of the jet of the other one. The jet that is closer to the door is five degrees ...

When air sterility is compulsory in certain activities, one of the solutions with which these requirements are obtained are the Dif-Vent and Dif-Pur diffusers, designed by the innovation department of Airtècnics. They are fans with diffusers provided with HEPA and ULPA absolute filtration stages. These products of the ventilation catalogue are the indicated ones in sectors where air quality is an essential requirement for its operation. The healthcare, pharmaceutical, food or technology industries need extremely pure air so as not to compromise the nature of the service they ...

An ECFanGrid project is a fan wall consisting of several EC motor turbines operating in parallel. ECFanGrid retrofit projects are mounted on a metal plate with all hardware to fit the internal dimensions of the AHU. This solution is intended to replace direct or DC drives, which consume a lot of energy and are costly to maintain. This solution provides energy savings of more than 50% in some applications (according to IEC 60034-30), with efficiencies higher than IE5. Our partners at Rosenberg France were successful in a project to replace a belt and pulley fan in a factory of one ...

Some projects require unobtrusive installations for ventilation equipment. The Invisair air curtains model from the Airtècnics catalogue fulfils this function perfectly. Invisair air curtains are part of the recessed range. They have a very special characteristic; the expulsion is made through a nozzle that leaves a reduced space for the expulsion slats. The installation we present here was carried out by the French distributor Exeltec. Together with the engineering firm Lefort Francheteau, has come up with a very special design for the historic building that houses the ...

During winter or in places where freezing and snowy weather conditions are common, air curtains are the perfect ally to preserve indoor comfort and save energy. Our partner Rosenberg carried out an installation in a factory warehouse in the small German town of Burladingen, south of Stuttgart, near the Swavian Mounts. There, during the winter, the snowfalls are intense, and the temperatures are very low.The air curtain model chosen for this installation was Maxwell, which is part of the range of industrial air curtains. It perfectly adjusts to the client's needs because it has ...

The end of the year is approaching and it is usual at this time of the year to take stock of the objectives set and the achievements made. In Airtècnics, within the quality policy of continuous improvement, we want to recapitulate and share these achievements of the year 2022.Expansion of the production facilities with a new building for ventilation units and heating coils for air curtains.Installation of solar panels in the second hall, which now has 100% self-consumption of energy and more than 100% energy generation compared to consumption.Product ...

The control and regulation of air curtains is essential to ensure energy and cost savings. This is achieved when the performance of the devices is adapted to each circumstance. Airtècnics has developed its own regulation systems for its products: the basic control and the CLEVER advanced control.The controls are designed with a simple and quick “Plug&Play” connection by means of a telephone cable with RJ45 connectors, thus avoiding errors. In this way, the connection between the control panel and the air curtain is established reliably, and no information ...
