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.

EVOjet™ – 30 – 50 % reduction in resin
consumption / No resin spots on the board
surface
PROjet –
resin savings up to 12 %
The EVOjet™ system is a dry blending
system allowing blending of MDF fibers
right after the drying process. 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.
