Ventilation system for the tower section of the older Käina factory
We built a fan-based ventilation solution for part of the tower and added to it — as is our custom — smart automation that controls the fans' operation based on the internal temperature.

The project challenge
In the production of plastic bags, the machines generate a great deal of heat, putting pressure on both human well-being and equipment performance. The specifics of the process require a tall space, which is why a "tower" has been built onto the older part of the production area, where most of the heat accumulates. Managing precisely this heat load was the core of the task.
How we built it
We built a fan-based ventilation solution for the tower section and added — as is our custom — smart automation that controls the operation of the fans based on the indoor temperature.
- A fan-based ventilation system for the tower section where heat accumulates
- Automation that controls fan operation based on the indoor temperature
- The option to choose whether the fans extract air from the building or push fresh air in
What we achieved
- As a result of testing carried out in hot summer weather, the indoor air in the production area is good
- Reduced thermal load supports both employee well-being and equipment performance
- Flexible control: the client can choose between extracting air out or pushing fresh air in
- Automatic, temperature-based operation ensures ventilation exactly when it is needed
