Products  > Technidyne ACA PERMI POROSITY


ACA Permi is the best tool to balance your process stability and product quality. On-line air permeability measurement provided by PERMI monitors your process and quality factors and keeps you on the safe side.


Optimize refining, retention, broke addition, vacuum levels and any of the machine variables that make paper, not just good paper, but the best possible product.

Improve and Maintain the stability of the structure of your paper – less broke, lower operation costs and a higher quality product.

  • Production increase of a liquid packaging board machine from 576 ton/day up to 648 ton/day.d higher quality paper for your customers.
  • Speed increase of a cigarette paper machine from 300 m/min to 400 m/min (25 %).
  • Much faster grade changes in production of nonwovens.
  • Energy savings up to 10 kWh/ton with better control of refining.
