Greenline+ is here to revolutionize fume cupboard user interfaces. With its innovate technology, Greenline+ promises to transform the energy efficiency of fume cupboards and elevate user safety to an entirely new level. The new AutoOpen and FlowRateSelect functions make the interface even more versatile.
Greenline+ was first launched in 2024. As a joint innovation by Visu Kaluste and Fanison, it offers a new approach to fume cupboard user interfaces, guiding and assisting users in operating the sash correctly and safely. Learning requires no separate training as users learn the correct sash operation intuitively as they use the fume cupboard.
In addition to intuitive learning and enhanced user safety, Greenline+ also promotes energy savings. The interface ensures that the sash is lowered when the fume cupboard is not in use.
Greenline+ appears to the user as a glowing color‑coded guidance light on the side panel and as clear information on the user panel.
Greenline+ consists of four main components and their intelligent integration into the VISU fume cupboard and the Fanison control system. The four core components of the interface are:
- AutoOpen
- AutoClose
- VisualGuide
- FlowRateSelect
The 2026 update introduces two new functionalities: AutoOpen and FlowRateSelect.
Auto Open automation brings ease to sash operation
Thanks to the new AutoOpen functionality, the fume cupboard sash opens automatically to the standard working height. This allows work to begin without contamination risk and without touching the sash.
The AutoOpen function is activated by the light curtain located beneath the sash. If desired, AutoOpen can also be disabled for individual fume cupboards.
During use, the sash can be adjusted touch‑free, for example, raised higher within the limits of safe airflow. The automation returns the sash to the working height once the additional height is not needed anymore.
Flow Rate Select – airflow tailored to different needs
The 2026 update introduces the ability to fine‑tune extraction performance to the level required by the task. This FlowRateSelect feature further enhances user safety and strengthens the versatility of the fume cupboard.
In addition to the normal mode, two other options are available: Boost and Eco. The colour of the side light indicates the currently selected airflow mode.
- The purple color of Boost mode signifies increased airflow. In this mode, the extraction setpoint is raised by 40%, which is typically sufficient even for more demanding work situations. At the same time, the alarm threshold is increased accordingly. It is important to note that the boosted airflow consumes more extraction capacity and may therefore affect the performance of other fume cupboards.
- The yellow color of Eco mode indicates reduced airflow, where both the extraction setpoint and alarm threshold are lowered by 20%. This airflow level is particularly suitable for low‑hazard work, allowing extraction capacity to be allocated to other fume cupboards. Even at the reduced airflow level, the system maintains user safety and ensures adequate protection.
The 2024 version of Greenline+ continues to operate as before. If you are interested in the new features, please contact our specialists.
