TFC series


Drying tunnel for spraying booths and roller coater machines.

The exclusive side ventilation allows a more uniform drying and reduces the overall length of the tunnel, optimizing energy consumption and reducing operating temperatures. Available with standard working widths from

 1800 to 3400 mm.







TFC Triple series 

The three-store version of the TFC tunnel is the ideal solution for small spaces and to limit energy consumption. 

Compared to a traditional tunnel of the same length, the time of permanence of the leather in the tunnel is 2.5 times longer. 

Thanks to the automatic conveyors, the grain is always kept facing upwards.

TFC Hybrid series

Fratelli Carlessi has developed a new hybrid system that combines the advantages of TFC with radiant energy systems and makes the drying process much more flexible. 

The addition of infrared lamps makes it possible to increase the heating power of a single element or the entire tunnel. 

The power can be controlled for every single element in order to increase the heating capacity in presence of high loads of pigment sprayed or deposited with the roller-coater.

TES series 


Electricity Powered tunnel

I tunnel Radiant tunnels combine the advantages of the absence of moving air masses (such as the lack of dust) and the stability of the leathers inside the tunnel. 

Unlike ventilated tunnels, radiant tunnels have a much more compact structure. They are available in two versions: radiant panels (TES/S) and infrared (TES/IR)

The TES/S tunnel has long wave radiant energy panels, which cover the entire upper surface of the tunnel. This allows uniform heat transmission and therefore optimal drying for a high quality finished product. The main feature of the TES/S tunnel is its flexibility as it can dry different types of leather and even very thin ones. 

The TES/IR tunnel, unlike the radiant panel tunnel, is equipped with medium wave infrared quartz lamps.
