Allnorth provided detailed engineering services for the installation of a 3rd press top felt and vacuum system upgrade for the No 3 Pulp Machine. New Uhle boxes were also installed on the 1st, 2nd and 3rd presses. As part of the Grade 20 CCE design work, Allnorth completed a vacuum system audit to determine if the existing system had the capacity to support the new 3rd press top felt Uhle box. The six existing vacuum pumps were replaced and numerous piping changes were incorporated, including the addition of new vacuum separators on each press. The vacuum audit determined that the couch low vacuum zone was not required for normal operation.
The use of laser point cloud scanning of the existing plant enabled the design of new piping and equipment in a very congested area without piping or equipment interference.
