High pressure water humidifier in BDN - Wykroty - Poland
BDN Sp. z o.o., Rotogravure Printing House located in Wykroty, near Bolesławiec, is a company that prints newspapers and magazines. The production process, in terms of quality and volumes, is the largest and most advanced in Poland. The facilities cover a surface area of around 195,000 m2, with an effective production area of 68,000m2.
The level of air humidity is a significant factor in the printing industry due to the properties of paper: this is made from cellulose, that is, plant fibres that are intrinsically hygroscopic.
The moisture content of the paper naturally tends towards equilibrium with the ambient relative humidity.
For example, at a temperature of 20 °C, the moisture content may be around 6% by weight at a relative humidity of 40%, which increases to 7% when the relative humidity is 60%. This increase causes variations in the dimensions of the plant fibres and consequently the sheet of paper, which shrinks when the humidity decreases and lengthens when it increases. As a practical example, a sheet of paper measuring two A4 sheets in width becomes 1 mm longer when the humidity increases by 10%.
With over thirty years of experience in the production of humidity control systems, CAREL is the most solid and reliable partner for the printing industry.
The exclusive distributor for the Poland, Alfaco Polska – through Mr Franciszek Klimosz, with in-depth knowledge of the application and experience acquired in the field, provided the support needed to supply the best solution for humidity control in the production process.
