Cooling Tunnels – Automated Component Cooling for the Stator Production Line
At AS Konesko's new Türi-Alliku factory, we built two dedicated cooling tunnels that cool the stator components exiting the heating furnace to the desired temperature within a maximum of one hour. The tunnels' forced-cooling fans are connected to the control automation via frequency converters, which measure the component's surface temperature and continuously adjust the operating speed of the blowers using an algorithm. The solution accounts for varying component mass and fluctuating ambient temperature, ensuring a faster and more stable production process.


Project challenge
The parts exiting the heating furnace prolonged the production process, as they could not be handled further immediately. The objective was to cool the parts to the client's desired temperature within a maximum of one hour. The task was made complex by the fact that the mass of the parts varies and the time required for cooling may vary across products.
How we built it
To solve the task, we manufactured two cooling tunnels to create forced cooling. We connected the fans through frequency converters to the control automation, which regulates the operation of the blowers based on data measured in real time. Using an algorithm, the control automation knows at what frequency to keep the fans running so that the parts are sufficiently cooled by the specified time. Since the ambient temperature fluctuates, the temperature of the parts is continuously monitored and the program continuously adjusts the operating speed of the fans based on the input information.

Extraction and filtration solution for metalworking benches serving 8 workstations
We designed and installed an extraction and filtration solution for a metalworking shop where 8 machine tools generated haze and emulsion in the air. Each machine was fitted with an OUF centrifugal oil separator and a shared GRAM CLEAN AIR filter FL 104, which returns the cleaned air back into production. The system starts based on the machine tools' signal and ensures cleaner room air and healthier working conditions.
Factory Welding and General Ventilation Upgrade
We upgraded the welding and general ventilation at the factory of Metagrupp, a manufacturer of welded aluminium products, and built a custom-designed separate system for the cooling units of the lasers. In the enclosed welding booths, we utilised the existing ductwork and added a GRAM filter unit, while the general ventilation was addressed with a CIC unit. The result is fresh air reaching the workers, normal air circulation and an energy-efficient solution that is ready for process automation and integration with other machines.
LEGUAN factory ventilation
Elister calculated and installed heat-recovery fresh air ventilation for the production hall, which the previous welding solution with filter towers did not include. The work covered design, measurements, as well as a turnkey solution.
