EVOjet™- and PROjet systems Increased efficiency of MDF production – significant resin savings Dieffenbacher has successfully completed the market introduction of the new EVOjet™- and PROjet systems. In several MDF production lines the EVOjet™ system has proven its high efficiency and has achieved resin savings in a range from 30 to 50 %. Several production lines using the new PROjet technique could reduce resin consumption by 4 to 12 %. Dieffenbacher has acquired an exclusive licence for all world markets except for North America for the EVOjet™ system. The PROjet technique is exclusively marketed worldwide by Dieffenbacher.

The EVOjet™ system, for the first time, allows making full use of all advantages resulting from posi­ tioning the process step of “Blending” after fiber drying. The result is a significant re­­ duction in resin consumption and elimination of additional emissions in the dryer exhaust gas flow typically generated by blending before drying. Also the PROjet technique is successfully being used in several production plants and has achieved resin savings ranging from 4 to 12 % keeping the physical properties of the produced boards constant.
