Despite reduced energy use, existing LC pulpers can improve the quality of the pulped stock at low consistency, up to 8% stock consistency. Voith Paper has successfully upgraded LC pulpers with IntensaTechnology around the world, in Japan, North America, Germany, and other European countries. Four more IntensaTechnology upgrades are planned for the end of 2009 in Brazil and 2010 in Thailand.

This unique concept, which has been available on the market for almost two years, consists of three main components. A specially designed IntensaDeflector improves the flow geometry for fast bale submergence and improved agitation. An optimized or new rotor accelerates pulping. A bale breaker is also installed in the pulper.

Thanks to the energy savings of up to 30%, upgrading an LC pulper to IntensaTechnology can result in a return on investment in six months. In addition to the energy savings, customers benefit from more reliable pulper operation, higher stock consistency, a higher operating level, and increased capacity when required.

IntensaTechnology can be applied to almost any LC pulper type from a variety of manufacturers. Voith Paper offers a pre-rebuild analysis.
