Feedback from the user

“Different CREApro control modules were implemented focusing on aeration process optimization, to increase process control and reliability and reduce energy costs. The project was implemented in great coordination with Createch360º and site teams, who still work closely together as Createch360º provides on-going support. The savings achieved were higher than expected within the validation period, and have remained consistent ever since, despite increasing loads.”
