The removal of solvents (and VOCs in general) from a Heidelberg press line was the problem of a European player in the paper box industry.
The company works exclusively in the luxury sector and the special finishes requested by customers often require the use of special paints with a high solvent content.
The Depurex photocatalytic filtration system was chosen because it satisfied the company’s needs, not only in terms of reaching the abatement target imposed by law, but also for:
– guarantee and constancy of the solvent abatement performance (certified by 6 months of continuous analysis);
– Programmable, simple and autonomous filter replacement, without creating dust or dirt in the working environment;
– limited system footprint.
The installation has been in operation since 2011 and the line produces an average of 1.5 shifts/day. The filters are replaced every 6 months.
