The infrared drying tunnel (the ‘IR tunnel’) has been designed to meet quality demands for finished product.
The tunnel heats using medium waves infrared lamps that reach the emission levels required in a very short space of time, thereby reducing wait times for starting work, to a minimum.
Power is regulated by means of an electronic control system (PLC) with “touch screen” device that guarantees regulation of the radiating power up to 4 drying stages.
The control system monitors in continuous the temperature of the leather coming out from the tunnel, by an optical pyrometer and adjust the power to the lamps.
The possibility of monitoring the surface temperature of the skin also ensures process repeatability levels at any time of the year.
A considerable saving in terms of used energy is given by the “energy saving” system of power sent to the lamps that automatically modulates to a minimum power.
Another key feature of this tunnel is the possibility of its working even without the internal fan. This reduces the possibility of contaminating leather surfaces with dust.
