Double-Wall Heat Exchangers

Armstrong Double-Wall Heat Exchangers For Potable Water and Process Heating and Cooling Systems After extensive design and testing, Armstrong has developed the new, highly efficient and cost effective double-wall heat exchanger with a number of unique fea- tures. The double-wall tube-in-tube construction provides positive indication of potential cross contamination between the shellside and the tubeside fluids. Should either tube fail due to corrosion, erosion, or abrasive action, the resulting leak is channeled between the tube walls to a vent space created by double tubesheets between the head...
