A.H. Lundberg, Inc. designs and supplies heat exchangers for the Pulp and Paper
Industry. Because of our knowledge of the pulp mill processes, our heat exchanger
designs incorporate the particulars of the processes into the design. When a process
stream contains fiber, that stream is handled on the tube side of the heat exchanger and
larger tube diameters are used to reduce or eliminate the fiber plugging the heat
exchanger. Also, materials of construction are selected to correspond to process needs.
Lundberg designed Heat Exchangers are ASME code stamped and, when applicable,
follow the standards of the Tubular Exchanger Manufacturers Association (TEMA). Heat
exchangers are designed for steam heating of process streams, for cooling or for heat
exchange between two process fluids.
Designs may incorporate multi-pass tube and/or shell units. The designs vary as required
for both heat transfer requirements and pressure drops through both tube and shell sides.
