Jeven TurboFlow VAV system with Fidelix-based control
Advanced professional kitchen ventilation systems designed by Jeven
Jeven’s ventilation solutions have created safe and comfortable working environments for countless kitchens since 1989. Jeven is a part of the Absolent Air Care Group.
Jeven’s solutions are globally known for their high quality, combining energy efficiency, indoor air quality, and operational reliability in demanding kitchen environments.
Heat recovery in kitchen ventilation: solving grease challenges without compromise
As heat recovery becomes standard in modern kitchen ventilation, grease—especially fine and gaseous particles—remains a critical technical constraint. It can accumulate in heat exchangers, reducing performance and increasing maintenance requirements.
While filtration technologies have evolved, many solutions still rely on conventional technologies, with poor filtration efficiency.
In many cases, these systems need to be larger and more complex than required, especially in environments such as schools, nursing homes, and catering facilities. At the same time, traditional grease separation methods may limit the effectiveness of heat recovery, creating a trade-off between air quality, energy efficiency, and system simplicity.
Jeven identified the need for a solution that removes this compromise.
High-efficiency grease filtration with separation and UVC air disinfection
Jeven developed the patented TurboSwing® (www.turboswing.tech) solution to address grease filtration with separation and air hygiene as a single, integrated function.
Jeven’s patented innovation, TurboSwing® combines high-efficiency grease filtration with separation, including gaseous grease with UVC radiation at a wavelength of 254 nm. This enables effective disinfection of exhaust air and duct surfaces, while maintaining stable and predictable filtration performance. Today, more than 70.000 units have been installed in various commercial kitchens in the Nordics and now expanding in Europe and Asia.
The high filtration efficiency also enables the use of low-temperature oxidation (LTO) systems without additional grease treatment. TurboSwing® separation rate remains high, even when airflows are reduced. This supports a simpler system architecture while improving overall energy efficiency.
Fidelix FX-SPIDER-X as the foundation of TurboFlow control
To complement its filtration and separation technology, Jeven has built its TurboFlow solution on Fidelix FX-SPIDER-X, which acts as the control foundation of the system. The system focuses on demand-based airflow at hood level. Each kitchen hood adjusts airflow through motorised dampers, ensuring that ventilation matches the actual need in real time.
Conditions under each hood are continuously monitored using sensors such as temperature and humidity. Based on this data, airflow is adjusted individually. A dishwasher and a grill, for example, create very different loads at different times, and the system responds accordingly.
Because airflow is controlled right where it matters, ventilation is only used when needed. This eliminates unnecessary airflow and results in significant energy savings, especially in kitchens with multiple hoods operating independently.
The system scales from single to multiple hood installations, while maintaining the same level of control and performance. At the same time, the solution remains simple to use, with local touchscreen access and seamless integration into building automation systems.
Scalable and energy-efficient kitchen ventilation solution
By using TurboFlow VAV-system, you will get proven solution: efficient filtration, comfortable, sustainable and cost effective kitchen environment. By combining Jeven UV filtration with integrated control, Jeven delivers a solution that maintains excellent heat recovery efficiency without grease-related performance loss while ensuring high air hygiene.
At the same time, the approach avoids unnecessary system complexity while remaining fully compatible with modern building automation environments.
The result is a technically balanced solution that supports easy maintenance and consistent long-term performance across different types of professional kitchen applications.
Jeven TurboFlow is used in projects such as the Marholmen Hotel and Congress venue in Sweden.
