Experience at Brigl & Bergmeister with new type of headbox

The MasterJet 4Tec represents the fourth generation of MasterJet headboxes from Voith Paper. This new generation offers significant advantages in four key areas, namely formation, pulsation damping, ease of operation and energy efficiency.

Compared to its predecessor, the already powerful MasterJet Pro, the MasterJet 4Tec offers significantly improved headbox jet quality. This is an excellent basis for very good formation values, no streakiness and therefore perfect paper properties.

Another highlight of the MasterJet 4Tec is the newly developed pulsation damper, which offers four essential advantages. It has a flexible membrane that separates the air volume from the pulp suspension, ensuring maximum cleanliness and stable machine operation. In addition, the damper does not generate any pressure loss, which reduces the energy consumption of the headbox pump. It also requires no cleaning, which saves fresh water, and is more compact and easier to install, even on existing machines.

Voith has also improved the operating comfort of the MasterJet 4Tec. An important innovation is the new EdgeMaster, which prevents the suspension from flowing off sideways. Its new design makes it easier to operate and effectively reduces edge waves.

In terms of energy efficiency, the MasterJet 4Tec uses several levers to reduce energy consumption, based on the proven MasterJet technology. Even with the previous MasterJet Pro, the cross-distributor does not require recirculation. This proven technology is also used in the MasterJet 4Tec. This reduces the volume flow to the headbox by up to 10%. In addition, the new pulsation damper and the optimized turbulence tube reduce the pressure loss at the headbox by around 25 percent.

In summary, the MasterJet 4Tec represents a significant advancement in headbox technology, offering considerable advantages in terms of paper quality, energy efficiency and ease of use.
