Chemineer’s Kenics heat exchanger efficiently and cost-effectively handles hot-melt adhesive products. At the heart of the heat exchanger is the static mixer technology which offers the high heat transfer coefficients for fast, uniform heat transfer.

The product consists of a continuous string of static mixer elements within each heat exchanger tube. Fluid flow is directed radially toward the pipe walls and back to the element, regardless of velocity. Additionally, momentum reversal and flow division also contributes to the mixing efficiency. All processed material is continuously and completely intermixed to eliminate radial gradients in temperature, velocity and material composition. As a result, this heat exchanger provides predictable, controlled mixing and highly efficient thermal transfer.

By using static mixer elements in each heat exchanger tube, the film buildup commonly associated with empty tubes can be significantly reduced. Process fluid is continuously pushed from the center of each tube to the wall and back to the center, eliminating thermal gradients and boosting the inside film coefficient. These elements produce a more uniform, consistent transfer process, with three to seven times greater heat transfer rates than empty tubes alone.

All the static mixer elements are furnace-brazed to the pipe walls. The enhanced surface area and internal fin effect augment the mixing action to dramatically enhance transfer rates. Removable elements are also available for applications requiring periodic cleaning during product changeovers.

    Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
