• With its structure able to withstand stresses as varied, this screen can adapt to many situations.

• The acceleration used in this type of device may be higher than in conventional screens, which generally gives better performance per square meter ofcloths.

• We can already consider that the screening surfaces will reduce a significant way for an equivalent flow:about 40%

• This allows the manufacture of screens less bulky and lighter for the same flow.

Innovation: Digital high performance trirol®

The new generation of horizontal screens is equipped with control device.
This function allows to push the limits of screening difficult materials.


  • • Changing the speed or angle of attack is very simple and without stopping the machine.
  • • Simply enter the desired setting and the device adjusts almost instantaneously while running.
  • • It can be programmed to self-cleaning sequences defined in order to adapt to the clogging or picking product.


  • Respect for the environment:noise reduction and lower energy consumption
    (anticipation of regulations and security requirements).
  • • Easy installation because more compact (less high than an inclined screen).
  • • Large space between decks for better ergonomics and maintenance.
