Supply air outlets for food industries and comercial kitchens

DQA and ECOJET displacement diffuser

REVEN GmbH and the SCHAKO Group have worked together to improve the DQA and ECOJET displacement diffusers. State-of-the-art tools, including CFD flow analysis, sound studios, an air duct with visible mist were used. The correct positioning of these fresh air outlets is very important to avoid disruptive air flows. The result is that fresh air is blown unnoticed into commercial kitchens and food production areas. This significantly improves working conditions and quality in production. This project demonstrates the importance of teamwork and innovation in demanding production environments.

Improving the quality of air in food production with the help of DQA and ECOJET displacement outlets. In the world of food production and commercial kitchens, the quality of the air supply plays a major role. To ensure that the ambient air is optimally regulated, companies such as REVEN GmbH have launched a development project that focuses on improving displacement diffusers. These diffusers, known as DQA and ECOJET, have the potential to significantly improve air quality in production facilities.


The development of REVEN GmbH and the SCHAKO CFD Competence Center

REVEN GmbH has teamed up with the SCHAKO Group’s CFD competence center to increase the performance and efficiency of its DQA and ECOJET displacement diffusers. This CFD competence center is located at SCHAKO IBERIA S.L.U. in San Mateo de Gállego near Zaragoza in Spain. Together they have started a project to optimize the technology behind these air outlets.

Modern tools and techniques

In order to improve the DQA and ECOJET displacement outlets, they used state-of-the-art tools and techniques. A central method was CFD flow analysis, which made it possible to examine and optimize the flow behaviour of these diffusers in detail. In addition, sound chambers were used to minimize noise generation, which is particularly important in commercial kitchens.

Test on the flow behavior of fresh air

But that was not all. The research teams carried out realistic tests in flow channels using fog machines.

This makes it possible to validate the results from the CFD simulations in the laboratory so that the optimized air outlets are actually effective in practice.


The importance of correct placement

The installation of DQA and ECOJET air diffusers on the ceiling requires precise planning. It is of the utmost importance that the air is supplied via air outlets that are outside the area of influence of the exhaust air thermal flow of the cooking and production systems. An unfavorable arrangement or poorly designed displacement outlets can cause cross flows and negatively affect the efficiency of the entire ventilation system.


Pleasant fresh air for your production

The intensive efforts to improve the DQA and ECOJET displacement outlets have paid off. The result of this project enables the imperceptible introduction of fresh supply air into the production of kitchens and foodstuffs. This innovation not only contributes to pleasant working conditions, but also to ensuring quality and hygiene in food production.

Overall, this project shows how collaboration between different experts and the use of cutting-edge technologies can help to improve air quality and efficiency in demanding production environments. The DQA and ECOJET displacement diffusers are an example of innovative solutions that are leading the food industry towards a cleaner and more effective future.
