Sappi Carmignano Improves Coat Drying and Reduces Energy Consumption

Ircon-Solaronics was selected by the Sappi group to improve the coat drying in their mill in Carmignano di Brenta (Italy). The project consisted by replacing an old inefficient gas infrared dryer (more than 30 years old) by a new UniDryer V3 system equipped with the latest generation of high intensity emitters.

For this project, Ircon-Solaronics offered solutions to reduce drastically the energy costs by:

1. Installing the UniDryer technology: The convective part of the UniDryer handles the mass transfer by blowing hot air coming from the emitter’s flue gases

2. Installing efficient emitters: The new Ircon-Solaronics Gem12-Hi emitters are the most efficient high intensity emitters on the market which results in a lower gas consumption

3. Energy Recovery: the hot air evacuated from the UniDryer system is reused as energy source for another machine component in order to reduce its energy consumption.

This kind of project has generally a short return-on-investment. Ircon-Solaronics is pleased to participate in this project which confirms its position as technology leader in optimizing the drying after coating stations.
