How can you prevent cross-contamination in shell and tube heat exchangers?

Double tube sheets are available for high purity and cGMP applications.

The double tube sheet design includes a glass safety chamber between the tube sheets. If any leaks occur, they will drain through the safety chamber instead of contaminating the other operating fluid. The glass safety chamber allows visual inspection of the tube sealing performance, allowing operations personnel to identify deteriorating seals and schedule maintenance during planned shutdowns. Fool proof prevention of cross-contamination not only gives you peace of mind but ensures high purity product and reduced product rework.
