Allnorth provided detailed engineering services for the upgrade of a No. 1 pulp machine fourdrinier table. In addition, new Uhle boxes were 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 fourdrinier table equipment. The four existing vacuum pumps were replaced with three new ones along with numerous piping changes. The vacuum audit determined the couch low vacuum zone was not required for normal operation.
The use of laser point cloud scanning of the existing area enabled the design of new piping and equipment in a very congested area without piping or equipment interference.
